catch can for pcv -oil in intake Any one experience the oil in the throttle body and intake tract yet?I just pulled my intake to paint it silver and already got oil in it.I know its a common problem with ls1's but come on i hardly put any miles yet.I started looking at catch cans and seen a few guys running air compressor filters inline.Any body using one or something different.
yeah I am running the Husky Air Compressor filter....as it seems many of us are. I havent gotten mine on the road yet really...only test n tune time...but I made that decision based on my research and it came up to be the best bang for the buck for my likes. So that is one route to go.

AMW makes a nice catch can setup... sponsor to the right. I know mine worked rather well.. not sure what's going on the new motor, wether it be breathers, the catch can/pcv setup, whatever...but I know I'd never not have a catch can on the factory PCV.
It is my understanding that is you really want to fix the problem, instead of putting a "band-aid" on it with a catch can, you can convert to the LS6 PCV configuration. It also get's rid of a bunch of hoses and tubes around the engine. I did mine using the guidleines at http://www.ls1howto.com/index.php?article=18. It was not difficult, though it was a little scary taking a Dremel cutoff wheel to the inside of my lifter valley. Cost was less $100 from a list price dealership parts seller.

Pat,My brothers 04 c5 already has this done and still gets oil up in it with less then 5000 miles on it.Just makes me wonder what else can be done about it.

A catch can may be in my future too.

My 2000 LS1 Corvette regular production pcv system with all of it's plumbing (actually just a plastic line or two) seems to work just fine....I get no oil in the intake.....and it uses absolutely zero oil between changes (every 3000 miles). I guess I can't complain about it. Maybe I just don't drive it hard enough.

i know GM redesigned the rings for 02, but mine is reved alot.. i tend to take it up high all the time between shifts, and i beat the **** out of it all the time, everyday..
yet ive never had to add oil between changes.. my car just doesnt use much oil. (yay!)
i think alot of that has to do with the fact that i drive it EVERYDAY.. well i did up until recently.. this last month, i stopped driving it as much.. i bought a new beater, and ive been driving that.
i'll watch my oil consumpsion, keep my driving habits, and see if how often you drive it really does make a diff....
I'm OLD.

I also switched and used mahle file to fit rings too in the build up.So john might be right and its ring flutter doing it.I drive like john does on and off the gas and long shifts,i love hearing the ls1 through the sidepipes and the low first gear of the 700 and 3.70 gears feels soooo good.
My 98 vette hasn't used oil, or burned it, except when going up a good long grade, if I stomped it, it smoked like crap out the tailpipes! I put the home depot air compressor fitting in line (right before intake) and it no longer smokes, even up a grade, high accel.
I reasoned that the reason mine sucked oil is that both PVC pickups are at the rear of the valve covers (so when racing, side G's one pickup won't be oil loaded) - so when going up a hill, the oil pools some at the rear of both valve covers, and it sucked oil, smoked like burning up.
Anyway, the air compressor filter worked great for me. Had it on for a couple of years, only drained the bowl a few times....

I think you hit on something there...what about the LS6 & 7 is the PVC there also?

theres a couple lines.
on the rear of the drivers valve cover, you have a connector, behind the manifold, it Ys into the rear passenger side cover hose.. then that whole hose runs forward along the passenger side fuel rail, to the PCV valve, then from the valve to the manifold.
the fresh air inlet goes from the throttlebody, to the front port on the passenger side cover.
