Everyone with oil temp issues

tbonesteak

This sucks.....evident from a few non-track junkies that spoke up, it seems like the car simply overheats from extensive exposure to traffic in warm temps....this should be very interesting....

Mr. Nash,
You keep making negative comments about Porsche. I don't get it. What's that have to do with Z's overheating. They build a FANTASTIC car. I have had several, have one now, and plan to buy more.

I started this post and the subject is "Everyone with oil temp issues." This clearly doesn't pertain to you. I don't know maybe it's the bra on your car that keeps it extra cool while you push it to the limit on tail of the dragon pushing those buttons to shift.

I have to agree.. while I'm always willing to entertain a contrarian - to a point - it really clicked with me when Alan pointed out that Nash is a Nissan sales rep... yuck

Robert_Nash

I'm not a Nissan sells rep nor do I work for a dealership nor do I receive any compensation from the sale of Nissan/Infiniti vehicles.

My point with using Porsche (and I could have chosen virtually any marquee at almost any price point) is that no one builds perfect cars nor always handles issues perfectly and immediately.

Porsche is a great company and builds great cars and I've never said nor would I ever say. However, with the Boxster issue particularly fresh in my mind (for reasons I had already explained above) is was an example of a car company that most high-performance aficionados respect but one who had a significant problem and, at lest early on, was reticent to address.

My only point was that nobody is perfect and nobody does it right all the time...there is no need to be offended on Porsche's behalf.

With that said, considering the turn of this thread, I am done with it and I think done with the forum as well; no offense directed toward anyone.

one notch above used car salesmen. Why do get the feeling he got axed from a Porsche dealer? Guess It's hard to sell 911's when your 90.

^^haha this thread has everything. drama, comedy, action, and sci fi.

SmartBomb has arrived at a theory regarding our overheating, and I believe it might be true with the exception that now everyday drivers are starting to exhibit overheating problems as mentioned in this thread. Please read the entire article as Technosquare had to cease dyno pulls due to overheating. I am filing a complaint with Nissan on Monday, and if Nissan gives me the runaround, then immediately thereafter I am filing, and urge others to file, a complaint with the NHTSA.


Nissan needs to get its a$$ spanked on this one as this is crap! Pure and simple. As far as I am concerned Nissan owes me an oil cooler!

Nice job Technosquare,

I've decided on a similar hose type, 910, in a 10AN size. This stuff is pricey, $17.30/ft., but the quality is top notch: It can make a bend 2 - 3 times tighter than the same AN size in regular SS braided. It is also much easier to put the fittings on this type hose. No Kul Tools needed.

Robert,

If you are not affiliated with Nissan then I apologize for making that statement. But you sure try to push their product.

The point here is that Nissan certainly appears to have known they had an issue and launched the car with their collective fingers crossed.

On the Boxsters, I don't recall anyone in my area being put off about a quick resolution. Customers were taken care of and customers came back as repeat customers. The question is what will Nissan do?

Along with the issue on the 996 I had a seal fail in the oil cooler console on my 88 944 Turbo S. The car was nearly a year out of warranty and Porsche picked up the bill. They only asked that I go ahead and do the service which was due at the time. That was an expensive repair as it necessitated the removal of the oil pan, new rod bearings, oil pump, water pump, complete flush and a lot of gaskets.

Oh, and they gave me a 911 to drive while it was in for repair. I didn't have to rent a Sentra as another member did when his 370Z gearbox went south.

Just found what I thought linked you to sales. It appears that possibly you supply parts/services to Nissan?

This does sound like you have an incentive judging by how you worded the above.

I didn't say I am not "connected" to Nissan nor have I tried to hide my connection. However, I would hope that most people would understand why I don't advertise it

What I said is that I am not a "sales rep" or work for a dealership (or have anything to do with the retail of Nissan products) nor do I receive compensation from the sale of Nissan/Infiniti vehicles.

There is nothing "secret" about the Nissan VPP discussed in the other thread and virtually all manufacturers have such a program - if anyone wants to know the details about Nissan's program I suggest they simply read the thread.

Robert, why don't you just spell out what your connection is? The VPP program is not in itself a connection, as companies widely make their employee purchase plans available to employees of other companies. As an employee of IBM, I have access to the VPP program from Nissan as well as those of other companies (like Ford, for instance). I can also have access to Apple's employee program. That doesn't mean I'm connected with Apple.

Robert, please just move on. This thread is becoming diluted and steering away from serving its purpose. Let's stay on topic peeps.

Alright guys, here's my experience. My Z is a typical daily driver and rarely race (street or track), but once in awhile I'll get a tad spirited as long as I keep in control for the sake of safety for everyone on the road. You don't need to drive fast to have run, right?

Anyhow, I've monitored the oil temp gauge during my usual commute. Initially it would hover at 180 deg. Once I get spirited with SyncroRev (still keeping revs below 4k regardless of how much trottle), the temps would over around 200 deg. The manual states 280 deg. is the absolute max.

Outside temp is 77 deg. with lots of wind (20+ mph).

I can only imagine what summer would be like, but that's my typical commute with freeway driving no more than 65mph.

Overall, conservative driving (paranoia) with 50% throttle to 4k rpm at times and lots of SynchroRev fun.

Technosquare did not write the article for 370z.com, I did. Why the oil gets hot is my opinion and a posible theory on why the VQ37VHR has high oil temps. Technosqaure just makes the kit and we tested it to see if it works.

If you don't do track days or other sorts of motorsports and run good synthetic oil and change it frequently, then you should not have problems. No need to get excessivly paranoid.

Most track driven cars should have an engine oil cooler. If you participate in motorsports then get the cooler for sure. If you don't, then don't worry so much.

260 degrees is where the properties of the bearings in the engine start to degrade, remember these are soft metals with low melting and softening points. Now there is quite a bit of reserve built into engines so 260 degrees under street driving condtions won't harm the engine. On the track there is a posibility. 280 degrees as the maximum safe temperature on the street is quite reasonable.

If your 370Z has an aftermarket turbo, you are hot lapping and your oil hits 260, time to stop. Same if you are loaded up with performance parts with your rev limit set higher. If your are hot lapping in a stock car and your temp hits 260, time to slow down and cool the oil. If you are in traffic on a hot day, the load on your engine is light and you can drive ok.

The VQ37VHR is not the only Nissan engine to run high oil temps. The RB26 and the SR20 do as well and those engines have pretty good reps.
