soo.. did you take pics of the plate? cuz there is no o-ring boss hole in the world that seals properly without both the underside of the fitting and the top of the hole being machined with seal surfaces. if it is not counter sunk or counter bored at the plate you need to use a dowty seal. and if its countersunk you cannot just break the thread it must be deep enough to provide a clean 360 degree seal.

Edit: the one in the video is counter-bored correctly so so long as yours looks like that than it had to be an assembly error(unless the counter bore is the wrong size). In the video at 0:45 that is what your' plate needs to have on that hole. I had one of the first original defective GTM kit's that had issues with the lines and my motor popped. I shut it off right away, removed the plate refilled it and drove it while i was getting replacement lines and my motor started throwing timing codes a month later because little pieces of the thrust bearing where plugging the oil passages to the cam actuators. You may not know your motor has had it's life shortened right away. (as a side note you saw how effective that factory oil pressure light is didn't you lol useless)

The second set of pictures shows the plate freshly installed. I think I have pictures when I first unboxed it but I haven't located them yet.

Most likely it is counter sunk and I couldn't see it from my angle under the car. I will have the part Friday around lunch and I will know for sure.

Nice to hear even if its running it may still be dead. And yes the oil light is useless. Had I not been paying attention to my mirrors I wouldn't have known anything.

So as an update. I have not received any I rings from the company.

In fairness I did inform the Brand Ambassador Tyler that I would not be keeping their product on my car. I have received a replacement from Z1 and it will be going on the car tomorrow morning. I have not received any communication from them since.

The shop put another slightly smaller o ring in the car and fired the engine. It will run but it needs more monitoring to know what's going on.

I should have the part tomorrow along with the full report from the dealer. I will post pictures of the part before it gets shipped back to amazon.

My guess is it was a misassembly at their factory and I would be cautious of trusting it is assembled correctly in the future. I probably should have taken it apart to inspect it but instead I chose to install the part how it came out of the box.

Not a surprise, unfortunately. They only respond when you make a public statement that could affect their sales.

I apologize for any miscommunication regarding this shipment. I had a chance to review the email string between you and our Customer Service rep Pat, and we did not ship these out next day air. These were mailed out via USPS on Monday, 9/9. Since we shipped these directly from our main office in Delaware, you should have received them by now. If you would like, I would be happy to re-ship these O-rings to you via FedEx, so we can provide a tracking number.

Thanks,
Tyler

Did they happen to mention what, if anything they were going to do if the failure of their part resulted in a dead motor down the line? Are you going to have to make a public stink about it before any action is taken on their end?

So my apologies on a slow update. I had been busy cleaning up the car and inspecting the front end over the weekend.

Finally got my car back Friday after they installed a new sandwich plate that Z1 got to me quickly. (Love those guys). That was $141 for diagnostics and (another) oil change. This doesn't include ordering another plate from Z1.

The engine is running, and seems to be holding her own. Something doesn't feel right but I think I've just been out of the car for a week.

As for the o rings that I requested. I never received the alleged USPS package. This is as of today 9/16. I specifically asked for them to be over night shipped. I was told the cut off was missed on Monday and they would ship Tuesday. It's a good thing I went another route and changed the plate. This is my only car and I couldn't afford to be without it for so long. I believe the not shipping the parts is poor customer service. It is on par with how I was treated concerning speaking with someone on the phone. I have been ignored when making requests to be contacted via phone and when I called the service rep was in a meeting and could not be reached.

As far as the part itself goes. Here is a picture of the plate post removal. As a note. We put the smaller oring and the sealant on it to check on the engine while waiting on proper replacement parts.

It appears to have a small counter sunk area. To me it doesn't seem to be as pronounced as the one in the video. The smaller o ring appears to have sealed it along with the high temp sealant.

Also, I have evidence it was a mis assembly. I was digging in my backup from my old iPhone and found the picture when I unboxed it and showed it to a friend of mine.

http://img.tapatalk.com/d/13/09/17/aqymajyr.jpg

In this picture there appears to be a gap between the plate and the cap.

As I said before I did not altar the plate before install and I didn't know it was supposed to be flush as there is nothing to accompany the plate as far as directions or recommendations.

As for the concerns about what they're do for the engine, Mishimoto's philosophy seems to be ignore the comments concerning damage and when directly asked say "Mishimoto's warranty only covers Mishimoto parts."

As for this part it is being accepted as a return to amazon. I'm shocked they are doing it but I'm thankful for a company that does provide customer service.

Bottom line is I realize it's a performance part and there are risks involved but something like this is not acceptable to me. I feel it is feasible to expect a part to come to you properly assembled. Again this is coming from my background in automotive parts inspection as an engineer.

Now that you posted all of this they'll come in and make some comment about their unsurpassed quality control. If you want a fast response, make a comment about their stuff they take offense to. Their VP will pm you and strongly advise you make a retraction. Bunch of assclowns.

They can make all the claims they want. Unless they have traceability data to show where the part was correctly assembled, it doesn't make a difference to me. They have no legal grounds to force a retraction and that would be further bad press for them. I am currently working on taking this to any forum that may use this plate as I believe it is important people know.

Spread the word, brother. People need to know the kind of garbage they make. Please tell me
youll take them to court if any motor issues arise.

I retracted a joke I made about them out of respect for AK, not because they had any legal case. They're touchy about being called out on making ****.

I will never let anyone I care about use Mishimoto products after seeing their thermostat fail on a good friends motor, causing it to blow. He sold the car and retired from the modding scene. I also had their thermostat fail, but I was more fortunate and didn't loose the motor.
Mishimoto is on the left w/ 4k miles on it, Stock unit is on right w/ 6k miles on it........... as you can see the O-ring seal is already gone on the mishimoto while the stock unit looks fine. QUALITY matters.

Forums are here to inform, throw some truth at the readers!

Cheap Chinese garbage. The saddest part is that their VP of something claimed in a pm to me that most of the guys who work there are enthusiasts with modded cars. If that's the case, they should feel really bad that they're foisting off low quality failure prone crap on other enthusiasts.

Now and then they'll get a positive review, and instead of using it to see that they're capable of making quality parts sometimes and just need to get their consistency under control, they use it to say they don't have any problems.

OP, did Mishimoto ever end up sending you those o-rings, or was Tyler just blowing smoke up you ***?

We have looked into our thermostatic sandwich plate to determine the exact source of the issue. Our engineers met last week with an O-ring sealing specialist from Parker to further examine the issue and have traced it to a small batch of inconsistent O-rings. These O-rings did not allow for the thermostat plug to be fully tightened. This is limited to just the most recent production lot of our thermostatic sandwich plates, and we are implementing several changes to address the issue.

We have immediately severed the relationship with the previous O-ring supplier, and will be using Parker O-rings for this product moving forward. They are higher quality and more reliable.

We have pulled all inventory of thermostatic sandwich plates from our warehouse and they are currently being re-worked by engineers in our Delaware office before being returned to stock.

We are adding a caution sticker to future production packaging to remind the user to double-check all plugs and fittings to assure they are fully tightened before running the vehicle. We are adding this information to our website as well.

If you currently own a Mishimoto Thermostatic Sandwich plate, and would like a replacement O-ring, please contact sales@mishimoto.com and we will send you a new one free of charge. Even if you are currently running our Thermostatic plate with no problem, and just want peace of mind.

We apologize for any inconveniences this may have caused, and will make sure that the quality of our products stand up to our expectations.

Chuck, where you at?

:roflpuke2:

I think this thread speaks for itself at this point. Our quality control is awesome, it's just that one of our suppliers ****** up. Assclowns, the whole lot of them. :rofl2:

And if the OP ends up losing a motor over this, it's a hell of a lot worse than an "inconvenience".

My question is:
Don't you guys do an incoming inspection on parts or batches of parts coming in?

Because it sounds a bit too convenient that you had an o-ring expert come in.

It's just damage control after the fact. They want something on the internet that can be googled so prospective buyers think the problem was solved and buy their parts.

Lol, I know that, but I'm wondering why this wasn't caught, at least learn from your mistakes, switching O-ring manufacturers is a cheap way out. And it's not a real way out, it's marketing.


EDIT: And as much as I love America, I don't hate Chinese made products a tenth as much as Chuck, just trying to make a point, and ask a valid question

Switching O-ring manufacuters is just a halfassed attempt to shift liability in case someone ends up with a toasted motor. Anybody who reads this thread and still buys their product needs their heads examined. They couldn't manage to get an envelope of O-rings in the mail to the OP, and lied/misled him about it numerous times. Shitty product, shittier support.

I'm not completely anti-Chinese parts, I'm just very outspoken about the companies that knock off real parts, and sell failure prone garbage to people because of slick marketing. I'm anti-crappy Chinese parts.

Switching manufacturers is not the cheap way out. We are actually paying more for a better quality, American made O-ring. These O-rings will be more consistent and to our standards, and our quality control will be increased. As I stated above, we are personally checking each plate that has an O-ring from this batch. We are taking the time to show you we care and make sure that everyone is getting the quality product that we intended.

Also, we did in fact get the O-rings to the OP, as he confirmed with me that he received them. We would not lie about sending out O-rings to a customer who needed them.

Anyone who reads this thread will see that we are not only active in the community, but we also care about our customers and want to ensure they get the highest quality product. People continue to buy and support our products, not only because of our quality products, but also because of our customer service. We try very hard to accommodate our customers and make sure they are happy with the products they have received.

Finally, I will state as I have before, that we do not sell knock off parts. We design and engineer all of our products in house, and then proceed to test them in house to guarantee quality products. Our products are not failure prone. We would not be able to have a lifetime warranty on our products if they were, as we would go bankrupt from giving out replacement parts. We have a very low failure rate, but as with any company, things still do happen. It's how the company handles that situation that shows their credibility.

To chim back in. (I've been busy working on the car and testing the motor)

I did receive the single o ring that was mailed to me. I never installed it because I sent the defective piece back to Amazon and took the 20% hit on restock. While it is good to see the problem being addressed well after my issue was found, the apology doesn't really help me. I stated to Mishimoto and here. This "inconvenience" cost me north of $350 not including sending samples of oil out to black stone for a before and after comparison.

To clarify my reasoning for the part chance. I did not feel Mishimoto had Any concern for my situation and I received some of the worst customer service throughout the ordeal. After being told the best they could do was mail another oring (which apparently is a lesser quality oring than should be used) it took 2 weeks (approximately) for the o ring to arrive.

It was replaced with a mocal plate thanks to Z1 actually shipping some thing on time and a method that wasn't first class mail. So far the engine is still running and is my daily driver so time will tell if something is wrong.

I have had several people pm me concerning their plates or potential purchases. I have been advising against this plate based on my experience with the company. Word has also spread around my area to be careful of these plates and I have helped two people replace them on local cars from our meets.

I honestly wished this plate had worked out. The Mocal plate is slower to warm up on cold days in East TN but the piece of mind is worth the inconvenience compared to losing 6.5 quarts of oil ( that discolors your Ark Exhaust, causes two aero panels to shear because it soaked into the panel, makes you replace front brake pads due to oil soak, and have the car towed to a dealer where it was kept for a week)

People weighing the pros and cons can decide for them self but as a quality engineer at a company that supplies almost every manufacturer that sells in NA I don't believe proper quality inspection is being competed on these parts which changes my mind on using anything they make. Luckily I learned this before I purchased a radiator to upgrade the cooling system. (Summers on the dragon get hot!)

Glad to hear the motor seems to be holding up. Now we can sit back and wait for Tyler to jump in here and tell us how great their parts are and how good their quality control is.

Wow, I bought one of these and was waiting to change my oil before installing it. I will be sticking with the non-thermostatic Mocal that came with the Z1 kit I have. Now I have to sell this thing...ugh.

...Anyone looking to buy a Mishimoto thermostatic sandwich plate? It's brand new!!!

Might be hard to sell it after this thread. Can you return it?

I'm not sure. I bought it a good while back...probably a couple of months ago. I will look into it.

SO OP DIDN'T GET HIS $350 OR THE DIFFERENCE AFTER THE PARTUNDER THE LIMITED LIFETIME GUARANTEE???

He just got a replacement part and o ring??? :mad:

All the political emails defending the company yet not sticking by the "No BS Warranty". At least not fully. And I'm really upset about how long it took ok to get help. And it infuriates me even more that his response came through a forum post and not to his personal phone or e mail.


No more biz from me..

Not even a new part, just an O-ring. One. And they lied to him about when it shipped out several times. No matter what their spin jockey has to say about it, the OP clearly was misled several times as to when it got shipped out.

For people new to this thread- they can't get an O-ring in the mail without ******* it up. Do you want to trust them with your motor?

Lots of promises from these companies until it's time to show and prove.

Sell it to a Mishimoto employee!

bet you they don't even run their own products.

Tyler loves the ****, he'll buy it off you. :rofl2:

How many Mishimoto employees do you think are willing to put their parts on their personal cars? Any of them? :rofl2:

Of course not. They know how many parts slip through their "quality control process". :rofl2:

nah they probably all run the american made prototype pieces

370Z Community:

I felt compelled to respond to this thread after reading through in detail. Every attempt was made to address the situation. We have been communicating with the community in a transparent manner to address this situation. Clearly we take our customer's satisfaction and our brand image very seriously. We pulled all of the inventory and inspected as well as ran internal leak tests. We did in fact bring an O ring expert from Parker company in to provide additional feedback. We have changed O Ring suppliers and are using this company moving forward. We swapped out all of the current O Rings with the new O Ring part as a precautionary measure. We have also implemented new torquing specs in our quality control process, although is should be noted that the inventory inspected was properly torqued. It should also be noted that this is a sole incident and we have not had any other reported issues.

While members like Chuck continue to troll this forum to try to get a rise, we hope that other members will read this and realize the extent the company has gone through to address and solve the issue. The part is a fantastic part. It was well engineered and it works great. This was an unfortunate incident and it has been addressed. Manufacturing is not perfect. Things happen - regardless of the level of quality control or where the part is made.

On a side note - Did you know the Challenger shuttle explosion stemmed from a faulty O-Ring?

CHALLENGER EXPLOSION

We manage 1,400 SKUs over dozens of makes and models and have produced hundreds of thousands of parts. Its only natural that something will go wrong at some point. While Chuck may chime in and say that we are only addressing this because it is on a forum - I call BS. The forums are a great tool to communicate with our consumers, whether good or bad. This should have been addressed prior, as 99% of issues are, during the initial phone call. This has been addressed internally. If we didn't offer great support 99% of the time, you would be hearing much more negativity from consumers. We wouldn't be able to offer a lifetime warranty on our parts if we weren't confident of the quality. The company has 40+ employees and four locations in three countries. We're in it for the long run - not to make one-time sales to customers. We frankly cannot afford to lose the trust in our consumers, which is why we go to the extent we do.

Regarding the service that Derraj06 has experienced.. Again - We have pulled our CSRs aside and have addressed the issue. We will be reaching out to provide you with a complimentary product or gift certificate to the website to accommodate you for your unfortunate experience. This should have been done sooner, and I apologize for that.

Best Regards,

Mike Sullivan
President
Mishimoto

good news is if your car blows up like the Challenger you'll still get a gift certificate

Well Mike, since you decided to mention me specifically, I'll respond directly to you. One, I'm not just randomly trolling your threads. I'm a former unsatisfied customer. As I've explained to Tyler, I've held parts your company made in my hands and noted their build quality. I've grudgingly used them on my car when I was in a pinch. I'm speaking from personal experience when i say the build quality of your parts is lacking. The radiator of yours I bought was significantly cheaper than the next best alternative, so i held my nose and used it for a short time. What you may consider "trying to get a rise" I consider "trying to keep fellow forum members from making the same mistakes I and the OP made". Two, I won't speak for the OP, but if I nearly lost my motor because of your sandwich plate, the offer for more of your parts would ring very hollow.

Lastly, your side note regarding the Challenger is incredibly tasteless. Seven Americans died because a contractor used an improper O-ring that was not rated for the purpose it was used for. Are you likening the OP's situation to the Challenger, since your faulty O-ring very nearly (and still might- these things aren't always immediate) made his motor a casualty? My side note- a company who feels it is OK to joke about an American tragedy in reference to this thread has no business getting butthurt and having Jeremy send me a PM asking for a retraction when I made a joke about child labor.

Uhhh! :barf: Truly disgusting comparing this to the US Challenger Xplosion!
When the OP spins his rod bearing(s) are u gonna front teh $$$$ for his new long block?
I've never bought mIshimoto...never have, never will! :thumbsdown:

Chuck,

Clearly that was not a joke. I'm not even going to respond to your nonsense of a statement.

Its a shame that you can't rise above your own selfish smug and look at the facts of this situation, as you would realize that unlike the bulk of the other manufacturers in the industry, Mishimoto is transparently addressing any issues and interacting with its consumers. What is ridiculous is that other threads with product failures/issues that I have seen on this forum go generally unnoticed or have little interaction from other members, let alone the manufacturer. Yet when a company does whats right in a situation like this - by not only doing due diligence in addressing the issue but in communicating that, they get bashed in a tyranny of childish rants.

With that said, we're closing the case on this one and will not continue the discussion unless it involves questions related to the fix or any other constructive conversation.

It will be a great day in history when (s)HitiM0t0 goes bankrupt 4 all the sh1++y products they have sold to the unknowing! Fawk 'em! :stirthepot:
