Hello,
I don't know if this in the right thread or not but here is my problem.
I am trying to figure out why I have oil inside my catch can?
I have two bungs to block and one hose coming from the oem valve cover breather. My car does not smoke at all but this is sometime a tiny bit of smoke coming out of catch can. The lines aren't ran perfect and might be a little short but I don't think that would be the problem. Can anyone help me with this? Thanks

I have a built ls/v on 17psi with a Garrett 60-1 and here is a picture of my bay and how to hoses are placed

 

The whole point of a catch can is to catch the oil blow by.

 

But it shouldn't fill up the whole catch can in a little over a week should it?

 

That would've been a good bit of information to mention in the original post.

Have you done a leak down test and/or a compression test?

How is your engine built? Stock specs or "race" specs?

 

I have done neither of those texts and it's
B18B shortblock
81.5mm CP pistons & rings - blue printed
EAGLE forged rods
OEM bearings blue printed (main & rod)
Canton Mecca catch can & fittings
Decked .001 for straightness
New OEM ITR timing belt
New OEM ITRwater pump
New OEM ITR oil pump

B16 cylinder head
CC'd and polished combustion camber
Ferrea stainless valves
Bronze valve guides
ITR valve springs
Crower chromoly retainers
98 spec ITR cams
Edelbrock Victor X manifold - ported & powder coated
King Motorsports OEM ITR bored to 65mm throttle body
SKUNK2 Pro series cam gears

 

I should've worded that better. Are the specs such as piston to wall and ring gap ect set to OEM specs or "race" specs? If you're built loose then you'll definitely push more oil versus a stock build but it also depends on how hard you're pushing the car.

Do a leak down and compression test.

 

Also, the catch can should be installed between the valve cover and PCV.

 

Blew my headgasket today, hopefully everything is okay and it'll solve the oil problem

 

Well that sucks. How many miles on the build?
