Catch can opinions
 

Has anyone used one of these guys from ECS? 1/3rd the price of weistec.

That was my thinking too but I see a lot of people spending $600+ for the Weistec one which through me for a loop. Also, do I want reverse or standard flow?

Good find - thanks for sharing. I think I'll get one too.

I think you'll want standard. Pretty sure the orientation of the pipes from crankcase to intake still needs to follow the same basic 'correct' principle (crankcase to catch can inlet > filter > catch can to intake manifold) but they offer a standard or 'reverse' flow if you need to fiddle with hose arrangement for the installation etc.... If I'm wrong, somebody please correct me.

This is a generic universal catch can. You need specific fittings for the C63. Only one I know of currently is weistec for $$

You have the fittings in the PCV.

Just yank the existing hose off and route new hose to a generic can.

It looks like the Weistec can is downstream from the PCV valve where this setup with the generic can is on the upstream side of the PCV valve. Is that correct? Would it make any difference?

The difference is that the Weistec catch can setup comes with fitting which connect inline with the PCV. Specifically made for the M156.
The set up from ECS (Turner) doesn't have that.

ADD has a baffled catch can for $99 (ADD W1 Baffled Oil Catch Can V3)

I am looking to install and catch can, so I read up all the threads and I don't think there is any one unanimus Catch can recommendation, based on built qulity, fitment , mounting points etc. Is there one that stands out? (apart from the $600 weistec one)
so far in the running:

1.ADD W1 Baffled Oil Catch Can V3
Looks like very good quality product, 3 different separator plates
(Someone mentioned putting steel wool? Woundering Why this and not the others?)

​​​​​​2.Mishimoto MMBCC-MSTWO-BK Black Compact Baffled 2-Port Oil Catch Can
Looks like this only has 1 separator plate vs the ADD W1

3. ECS Turner Baffled Oil Catch Can Kit - 6/8/10oz
Hard to tell but Looks a little more generic plastic, no real info.
says it's a 4 compartment unit VS what in the others?

Has anyone tried this option?

I found space for my not $600 oil catch can.

With a card board I was able to develop the basic form for my bracket to attach firmly my catch can.

Finally in Place

I installed an ECS catch can when I installed my ESS supercharger. If you look at my post for the ESS supercharger DIY installation, I put in several pictures of the catch can installation. It is easy to take the hose off between the original PCV valve pieces and just run the hoses to and from the catch can. The ECS can I got has an excellent baffle set-up and also a dip stick so you can easily tell how full it is without removing the can.

I am planning to do the same, Im waiting on a ESS supercharger and in the meantime Im preparing to have those small details ready before the ESS supercharger get here.

So far I already upgraded the pulleys to billet, changed the tensioner, got one step colder plugs and got the plugs for the injectors.

So do we have an ultimate decision and step by step guide on which can and how to install from A-Z?
I looked at your install @Big Jimbo but I'm still pretty lost as the guide is half pics/half words/half supercharger stuff.

I think I'm going to be creating a thread that will list every single Catch Can for sale for the M156 and then try to compile an actual photo by photo, step by step, for dummies guide somehow. (I know there's a bunch of threads but none of them are truly "for dummies" style).

Yes, my catch can installation was with a supercharger so may not be the best example for the "for dummies" write-up, but I mounted mine in roughly the same place but had to clear the coolant tank for the supercharger. The ECS can is very high quality and won't disappoint anyone from that standpoint. Make sure the hoses you run from the PVC to the can are as flexible as possible. That will make it MUCH easier.

ADD catch can. If it all works out with the hose/fittings and pcv I'll post more pics and details

Like most mentioned these catch cans aren't rocket science. Its a fairly straight forward setup. That ECS Unit looks the business! For a fraction of the Weistec Can its a no brainer (if install / parts are as easy as the Weistec units)

Owning the Weistec Catch Can, you can tell they didn't cut any corners on it. The thing is build like a tank. Pretty over kill for a catch can, but i love the build of it none-the-less.
