ecotec oil catch can installion

[dcw group]

This may be a stupid question but can a oil catch can be installed on a ecotec? if yes how can it be done? i have been looking everywhere for installation guide or some kind of idea on what to do.

Thanx in advance

Between the throttle body and the intake manifold there is a 10-15mm diameter hose that vents oil fumes from the rocker covers to the intake. If you want to be legal you can remove this hose, and route the fumes to a sealed catch can and from that back to the throttle body with either a drain tap and the bottom, or pipe it back into the sump.
If your looking for the not so legal option, block of the throttle part with a vacuum cap or a hose with a bolt in it...whatever takes your fancy. Then run the hose from the intake manifold to the catch can. (presumably you'll have one of those little breather filters on top? If possible, get one with baffles otherwise spirited driving will see oil all over your engine bay.)

This is how i believe it is done on buicks, pretty sure the ecotech uses a very similar breather system.
If you have trouble finding the right hose, you'll know you've found it when its completely full of S**T and oil.

Hope this helps.

Throw up some pics if your having trouble.

No worries

To stop oil from being sucked down the intake instead of just the oil fumes.

On the Ecotec the PCV valve is located directly inside/under the inlet manifold/plenum, so you cant really connect an oil catch can to it without major mods to the inlet manifold. The engine vent hose that goes between the manifold/throttle body and the crankcase is just there to let fresh filtered air into the crankcase where it helps scavenge any blowly or crankcase vapours, then it exits the crankcase via the PCV valve which like I already said, is located inside the inlet manifold, where the scavenged gasses etc gets mixed with the engines incoming air, and then it gets consumed in the combustion process.
Theres no point connecting a catch can to the crankcase inlet vent pipe, as this wont stop any oil going through the PCV and into the inlet manifold. A catch can has to go between the PCV valve and the inlet manifold so it can "catch" any oil mist etc that gets sucked in through the PCV and into the inlet manifold with the blowby gasses etc.
The crankcase gasses can actually reverse and flow back through the crankcase inlet vent hose, and into the throttle body, but this only happens sometimes at full throttle, or when the engine is fairly worn and the blowby is too great for the PCV to control.

I'm keen for some pictures.
