Oil Catch Cans...
 

Looking for a Oil Catch can for my Stillen Supercharged 370z. Finding that oil Blow by is becoming an issue with my MAFS / Throttle Bodies. P010B is the code. Changed out Mafs and notice the oil slightly dripping. Any suggestions to a decent Can????

Any can that has a baffle in it is usually best. You could also use a can and thrown a scotch brite pot scrubber in it to help absorb the oil. You can find cheap cans on Amazon all day. Then pick up some 3/8 hoses and a few hose clamps and you're good to go.

I actually just bought these ($50/ea):

which is the generic version of this mishimoto can ($120/ea):

Unless you are a brand fanboy, I would stay away from Mishimoto as almost all of their catch cans are generic ones that they labeled as their own and marked the price up 3X.

You might go with something less expensive though... I chose this particular model because I am boosted and this can is able to be pressurized. Just make sure you get something with some kind of oil separation... or plan to DIY your own separator as mlsully detailed.

Care to post some pics of the internals of the generic catch can if you haven’t already got it installed?

I can do it tonight... they are literally identical to the mishimoto version though.

These are the ones I bought. It’s only 2 port, so you have to use 2 or add a “T” into your line for each side. Picture of what mine looks like installed with braided hoses.

Those models are cool because they have that little chamber you can use to stuff whatever oil separation material you want in... I was actually going to go with those and modify them to accept a 50 micron pneumatic filter for oil separation but I ended up returning them because I didn't think they would play well with boost (that dipstick didn't look sealed) and I didn't want to also have to relocate the PCV check valve. Nice cans though, and CHEAP at $35/ea.

The ones I ended up with already use a pneumatic filter for oil separation..but are more expensive and the fittings need to be replaced because the included ones are too big for our cars... for me it was a no brainer though because of boost.

Those are some expensive catch cans. What's special about them?

Expensive is subjective. Its not about the money its what drives the passion and to answer your question nothing. It all serves the same propose. There just pretty and of high quality...People were talking about catch cans so I just put them out there for reference.

Sorry don't mean to be disrespectful, I'm on the market for a couple catch cans myself right now, and just wanted to know the difference between those ones and the other two linked before.

I noticed that the ones mlsully posted are empty inside. There is even a version with a filter thingy on the top which I have no idea what's for.

The filter thingy is a breather vent for the catch cans.

You definitely do not want one that is just an empty can unless you plan to modify it to add something to separate the vapors from the air (since that is the purpose of running a catch can). Almost all the super cheap cans will just be empty cans. The ones mlsully posted are empty, but they come with a little chamber you can fill with something to cause the vapors to condense and gather on.. most commonly people use stainless steel dish scubbing pads (pro tip: you can get them at the dollar store). So this type of can, while empty, can easily be adapted into being functional.

As far as the ones with the breather vents - if you are going to delete the PCV system you would run one of these with the breather vented to atmosphere though the filter... If you are going to add the can into the OEM closed loop PCV, you want one without the breather vent. Some can be configured either way.

Thanks for the information, very helpful. For the Catch Can you posted, do you only buy one?

I am going to run two...but you could run just one. just need to run the lines from both sides to the single can.

But the Can has 3 ports. Unless you have 2-port version, in which I would love to have the link, please.

Yup.. Has two in's and one out. I am going to plug one of the in's.

I can't remember where, but I did find the two port version unbranded, but it was more expensive so I bought the three port versions with the plan to plug the extra port.

I think I'll go this route myself too. Couldn't find the 2 port version, but I did find the one you linked on eBay for $30:

I will pair that with these SS hoses from eBay too, and I think I'm good to go:

Nice find/price! Good luck and post up some pics when you finish the project!

Here are links to the fittings I ordered for this project... I didn't really like what was available in the plumbing section of the hardware store.

Hope this helps someone following in the same path.

You don't like the hose barbs that comes with the cans?

I think they're a little too big..they are for 1/2" tube.

A little update on my progress #NobodyMoveThisIsAThreadJacking

I relocated/redid the filler neck for my DIY washer bottle to free up the passenger side airbox mount for one of the cans.

I also made up some aluminum mounting brackets for the cans themselves... today I'll pick up my grainger items but then this project will probably sit idle for a while as we are focusing on moving into our first home right now and I am going skiiing in Montana next week.

Does anyone know where I can pick up an assortment of the OEM-looking black spring hose clamps?

They have properly sized ones at my local Ace Hardware...but for whatever reason they are camo green and I feel like that would annoy me. I'll also see if Grainger has any that will fit (it does appear they have a few sizes available) when I pick up my fittings, but I would love to have a case of like 100 in assorted sizes. I have seen some inexpensive kits on amazon, but they are all gold colored and the reviews often speak of them breaking.

Get this .. has both pcv ports .. and coolant .. best of both words and it looks oem.. cant beat it

I just bought a Rampage Fab Combo Catch Can and am getting installed by them tomorrow morning. Cleanest looking set up IMO.

I have the Admin Tuning combo catch can.I did not know of Rampage.That Rampage looks great.I like the Combo catch cans.They clean up the engine bay.

It was warm today, so I got the chance to install them, here's some pics:

That looks great! Where did you get those fittings?

Those are exactly the same ones you posted from Grainger, I just sprayed them with black paint.

LOL gotcha =) Looks clean! hope mine turns out as nice.

Catch Can
 

Just got my catch can today.

Looks great.. I also would have preferred the 2-port but I can't stand the idea of giving Mishimoto money... particularly since they are just badging a generic product but telling the world they "engineered" it.

Flushed my oil cans today, after 1000 miles of installation, with my oil change:

The picture is from the driver side. Passenger side was practically empty. I feel like this is a lot of oil from only 1000 miles.

Excuse to show catch can.After 2nd atempt at powder coat.

well it only took like 7 months, but I finally got around to installing my catch cans... Please excuse my filthy engine compartment.

Won't get to test drive for a while unfortunately... Right now my car is stranded in the garage as they are redoing my driveway... should be done Monday or Tuesday but I'm traveling all week for work anyway.

All of you guys with the Mishimoto or similar catch cans... excellent choice. I had them installed before selling the car.

Huge lesson learned was when I initially purchased the cheap GodSpeed universal catch cans - vacuum leaks galore! I tried using epoxy to seal it up however I could, but still heard the hissing noise. Next huge lesson learned was silicone vacuum lines for PCV routing. The lines would "sweat" oil, get soft, and break at the clamps causing idle to jump all over the place.
