Pcv oil consumption
I have kinda of heard that ls1 s have a shitty pcv system and read some brief stuff on here about it. Does anyone have this problem. I usually go through a quart at least in 3k. But I recently put in a new pcv valve and hoping that takes care of some of it. I also seen a redesigned pcv valve I think it was on lmperfomance, has anyone tried that.

Oh and no leaks or anything, so I am assuming its from the pcv system. and when I gun it all the way I can see a little smoke from the exhaust.

A good catch can will make a big difference in not pulling the oil mist into the intake. As stated above, it doesn't reduce the amount of oil used throught the PCV but does keep it out of the intake system.

I don't think it makes a huge difference, but it keeps more crap out of the valve, that's for sure.

Cant I just put in a breather and get rid of the pcv valve and cap off the ends. I have heard of the catch can before, But I dont get why people dont just throw on breathers. I guess I was just trying to find a really cheap solution before buying the can or whatever I m going to do.

The breather is just ventilation, it is not a vacuum like you get when setup as described. Just the breather makes the inside of the car stink if you have fans or AC on also... gets that burned oil smell.
A can/trap is about $10 dollars, that is definitely cheaper than a breather too...
Something like this with 2 screw in barb fittings works: http://www.harborfreight.com/cpi/cta...emnumber=94346Last edited by Frost; 07-19-2009 at 08:29 AM.

Where do you install the trap?

Just before the entry to the manifold/TB (the vacuum source).
