View Full Version : Oil catch can - needed for SC applications?

Here's another one for the learned, I am to understand that a catch can is a good idea for a turbo applications to help eliminate oil in the intercoller and hence making it less efficient. Is this also the case for Super charged applications?
Sorry for all the silly questions but I am genuinely interested.
As always thanks in advance,
I run one on mine, in about 7000 Km's it's collected about 40Ml of oil, a lot of that might have been from breaking the fresh engine in before the rings sealed.

Yup I run one on mine as well (its an elite) and I usually just drain it whenever I service it, only drains a little bit of oil as well but saves that going into the intake.
What sort of blower do you have Top or Side mount ?

Top mount HTV1900, so quite interested to know the benefits of a catch can (also, are these legal? as I remember seeing a thread where it indicated that these were an issue with powwwlice - although, I am sure that this is also the case for a top mounted SC...)

Haha if you are running a SC I think a catch can is the least of your police worries!
The sealed units are legal. Mine catches about 60mls at a track day but I don't have a SC. Road use collection is minimal.

I run an elite can too. It used to get more oil in it before the blower to be honest. No idea why the blower would reduce it. Regardless, they're relatively very cheap and the elites at least are extremely easy to fit. No reason not to do it.

Just bought and installed an elite one on my LS3. My ASE one I had on the SS worked great. Hopefully this one will also. Looks great too.

I run Saikou Machi dual cans with my HTV. 1 can on the clean air side, a separate can on the dirty pcv side. Great price and he custom makes them to your specs if you wish.
I can't comment on the intercooler issue, but one reason to run them is to prevent oil being pulled into the intake from the PCV system, contaminating the intake charge. As I understand it the oil ,even in small quantities, will knock the effective octane levels down. Then PCM see's knock events, and pulls timing or whatever it does to prevent this, which amount to reduced power output (I'm not a tuner, so thats a bit vague description).
I certainly had oil in my manifold before fitting the cans, and nothing after. This is on a fresh engine, not a high k's engine with blow by.
Just my experience. Hope it helps, I did a large amount of research on PCV systems when I was looking into fitting my catch can, including talking with a GM tech in the states, as I wanted info on what was best (vented, non-vented, cleanside, dirtyside etc)
