Oil Catch Can, Rc Breather Or Pcv Line?

[luke187]

Theres no point plumbing in the catch can back into the intake unless you're using an oil air seperator - which is essentially a baffled catch can stuffed with steel wool or something similar as a filter. This suspends the oil and draws vapor out from the air before pluming back into the intake, if you just use an empty can then plumb it back into the intake its not really any different to the stock setup. If you dont care about legalities just use a can with a small filter that vents to atmosphere then paint it black and hide it on the firewall, cops will never notice it.

Is def not used as a inlet valve lubrication system though, the only reason its plumbed back to the intake is for emissions. The oil decreases the octane rating of the fuel or lowers the knock threshold, leaves carbon deposits in the intake manifold, cooler, and pistons/valves over longer periods of time - further decreasing the knock threshold.

I agree 100% with the post the only caveat I would add to the above is, if you run a vented can and higher boost than stock (ie any north of 10lbs) expect to be able to smell oil as the can with breath the vapour under boost/load.

I have a baffled can with mesh inside.

Yea I was also planning on filling the can with steel wool (pot scrubbers)

Thanks for clearing that up luke

Atmo ftw

If you're running atmo, why bother with the can?

So oil doesn't end up everywhere.

[timwds]

If you run a pipe down near the fuel filter there is no "oil everywhere". A small shiny spot on the chassis rail at most which never hurt anyone.

Edit: Also doesn't look like cop bait.

In 11 years of owning modified cars I've never had a cop pop the hood or give em the once over. Even when I had obnoxious sounding v8's.

I think it comes down to how you drive. How it looks, im not into external mods, wheels and a good stance is all I need, and obviously a bit of luck.

Same boat as barnz. Last time I got defected was about 9 years ago when I was a P plater driving aimlessly around in a bucket of d**ks LTD every night and probably deserved it. That being said, $10 says I get pulled over on my way to the shops tonight
