Catch Cans

[SanDiegoBlue]

I understand there are self-draining catch cans. This clearly eliminates the maintenance -- what is the down-side? If no downside, why aren't they all like that? Maybe y'all get satisfaction in emptying them out as it indicates they are working...

The Mishimoto can does have a drain on the bottom, but it's not a petcock. One downside I can see is that if it's a rinky-dink petcock it could leak. My thought is that the Mishimoto can's tapped drain on the bottom can accept a Fumoto drain valve. On the Mishimoto site. (1) they have a kit, but it's a barbed-filling kit which I think would b prone to leak. But they give the details on the size...it's common:



and I believe that this Fumoto Valve (110-N) will work:

I just install mine a couple of weeks ago and there is not a drain on the bottom, the whole can unscrews.

Same on my Mishimoto

Personally, I would NOT install a self-draining catch can. Have you seen some of the pictures with the gunk, oil and water mixtures that are in the catch can? There is no way I would want water draining back into the oil pan and mixing with the oil that circulates throughout the engine. Not going to happen for me!

The ADD W1 has a drain on the bottom. I bought their drain kit but haven't put it on yet. You can make your own with the right parts.

Yes and No. Yes, we don't want gunk back to the main oil pan. We're not talking about a self-draining can, we're talking about a can with a drain on the bottom for easier drain access. Mishimoto does make one, MMBCC-CB___. It may not have the fancier bracket for the Stinger, but that is not what matters most to me.

The PCV is to capture vapors that would otherwise be released to the atmosphere. Theoretically, you can direct the mess away from the engine altogether. But multiply by the MILLIONS of cars out there, and you back to the brown smog days of LA in the 80's!! Not a pleasant thing.


I think that this is what I am going to get after inspecting fuller specs (size/dimension) and create a way to install it. Got everything I need: baffled; bronze mist filter; and a drain port on the bottom.

Personally, I would rather be "inconvenienced" with having to unscrew the catch can once every few month, then the chance of a drain fitting leaking and getting oil all over the engine bay and road.

You probably don't want the ADDW1 one because it has the drain hole and connection but it is plugged. It would run a similar chance of leaking over time.

I already have the mishimoto can for stingers

INTERESTING ... The Mishimoto video for the Stinger install has a Catch Can WITH A DRAIN PORT ON THE BOTTOM!!! Approximately 1:34 - 1:38 into the video. I wonder why you guys are getting cans without the helpful feature?

It is a port to give you the option of buying their add-on kit Mishimoto Compact Baffled Oil Catch Can Petcock Drain Kit

Perhaps this is mostly a money-grab by Mishimoto, perhaps it is because there is enough people like me who would rather not pay more for a "convenience feature" that makes it less reliable (if the petcock or the pre hose fails then its an oil mess all over the engine).

I agree. I doubt that they are even pressure tested before leaving the factory. I've seen wayyyy too many fittings leak that were professionally installed in multimillion dollar vehicles... I would prefer to not have anything there if I'm not going to use it.

 

[NYBIOMED]

Am I correct in believing that an OCC is not quite as needed with the 2.5T because it is both port injected and GDI? Not that it would do nothing for the 2.5T, but just not the "intervention" that is is for the 3.3TT because that engine is singularly GDI.
?
TIA

I watched a couple more video installs and they both show the bottom plug for the drain that mine does not have. Which is good because I don't want a leaky drain fitting. Weird though.

I went with the Mishimoto single can. Easy install. Since this is the first one I’ve ever installed I took my time to make sure I knew what I was doing. After I had the correct screw for a post it took about 30minutes. The ‘22MY GT2 doesn’t have the screw post pre installed so I had to go to the store for a screw and nuts. It wasn’t difficult, just a bit of a PITA since it’s behind the wheel. I dropped a string from within the engine bay into the wheel well and then attached the screw to it and pulled it through the hole. I installed mine at 600miles - wish it had been sooner, but as you can see from the pic I’m glad I did. Here’s attached is a pic at 2800miles. It’s hard to get a good pic inside a black catch can. I’d estimate just over about 1.5 tablespoon.

Interesting, actually surprised at how much crud your can collected. Makes me happier that I now have one, two actually. Don
