Since I got my 00 coupe about a year ago it has used oil, about a quart every 400 miles if I drove it like it was meant to be driven. Didn't really use any if I drove it granny style. I was secretly sad because I figured this was the dreaded ring issue and there wasn't much I could do about it other than tear it apart etc... I would just add a quart as needed and try not to think about it. :skep:

Well, one of my heads blew up a few months ago and I had them replaced with a pair of ported 243's from Advanced Induction and have been driving the bejesus out of the car since. The oil hasn't dropped a mm since the head swap!

I love my little yellow buddy! (now without reservation) :dance:

Same thing I found too.

My 01 always used a little oil, since new. I typically had to add a quart mid-summer between it's yearly oil changes. I didn't consider that excessive consumption, but yet it was noticeably using it. (I only put 6-10k mi a year on the car)

Since swapping the heads nearly 3 years ago, it doesn't consume any oil at all now. I can drive it a whole year, and it's still right at the full mark when I change the oil.


I've seen others post of similar results, and I think based on our experiences there might have been a lot of needless piston ring replacement jobs done over the years.
Not saying in some cases the rings weren't the culprit...But it makes ya wonder how many people out there might have only needed needed fresh valve guides and seals to solve the issue? :bilmem:

So, apparently GM fixed the problem cuz my '03 doesn't use any oil.. Maybe I got lucky..

There were definitely some ring problems going on with the 01 Z06..but generally speaking, all the LSx engines have been quite popular candidates for oil consumption issues.

It's not a simple matter of identifying a single culprit and fixing it, it's more a matter of tolerances, and what GM lets slip out the door as being within tolerance and "acceptable".

I wish I could afford some performance heads... :(

I've got a 2000C5 Coupe myself, and my brother told me about a "catch-can," how it works, and the loss of motor oil, I've had my car better than 2 years now, and have used no oil :wtf:, been all the way cross country, and I'm known to hit WOT regularly, so I guess I'm fortunate. :takdir:

Do you have a catch can or not though? :D

I have a catch can... it has some oil in it when I check it so it seems to be doing its job. I haven't checked it since the head swap though.

Cool, seems my 99 uses some oil, must be when in boost though:)

What does an oil catch can do? :skep:

What does an oil catch can do? :skep:The PCV system is setup so that the intake manifold vacuum draws the crankcase vapors out of the engine. These vapors contain very minute traces of oil, which over time, collect and form puddles of oil in the intake manifold.
The oil that gets burned also helps to carbon up the pistons over time. In short, you need to let the crankcase breathe, but you want to burn as little oil as possible, and also keep it out of the manifold.

A catch can filters out these oil mist particles exiting the engine, and condenses them into a storage can before entering the intake manifold.

How do you get in boost on a stock car? :D

Thanks. I'd love to line em up sometime!:drivingskid:

I wanted to go with you guys on the 13th but can't get out of work, hopefully I can make the next one.
