Why you want an Oil Catch Can

[sjbsuperman1425]

I've had insurance on my car for a little less than a month now. I've been driving it since March 10th and have been very happy with it, although i have a slight oil leak..

As I was out checking for leaks (im very paranoid) i noticed my INTAKE SIDE catch can had some "stuff" in it. So i decided to empty her out..Lets just say my hands smell to high heaven, i have a headache/feel sick, and im very happy with my $20 purchase now.





It almost looks like oil/coolant mixed combined with the smell of exhaust. There was alot more, but i spilled it on my hands, hence me feeling a little erky now. Basically the bottom line is:

Oil Catch Can = WIN

Can you post how you have it set up, I am really thinking about getting one

[sjbsuperman1425]

I just ran hoses from the PCV to the catch can, then from the intake side valve cover to the catch can on the intake side..The exhaust side has one going from the intake tube to the catch can and then one from the exhaust valve cover to the catch can..pretty easy to setup.

wtf did you catch?

that doesnt look normal at all......

[sjbsuperman1425]

thats what i was thinking too. Its been fairly cold here, so I'm guessing its a mixture of water vapors and oil. But I really dont know. The oil and the coolant are in perfect condition though.

thats normal, its condensation and pukey blowby gasses that smell deadly.

My blow-by was more milkshake colored, but I had blown rings. I just built a new catch can that will pull right off of the oil filter mount and eliminates the tube under the intake manifold, the PCV valve, and the line going from the valve covers to the intake and turbo inlet.

I'll post pics of it when I get it finished and installed.

How does the turbo side look? The one on my intake side always filled up faster than the exhaust side.

[sjbsuperman1425]

my exhaust side was on for about a month or two last year and hasn't even filled up enough to register on the little "fill tube"

That's interesting

That's interesting

Why so?

[float_6969]

I would think there would be more blow-by when the turbo is spooled up and and making boost, as opposed to when the engine is braking.

[sjbsuperman1425]

i did noticed that in the tube coming from the exhaust valve cover to the catch can that there is oil "coked/burned" to the bottom of the tube. Im not sure if heat or anything would play a role into the blow-by or not. Anybody got any ideas of why the intake side might have more blow-by than the exhaust side?

I'm moderately interested in this as of now.
