99 and 00 ls1
So I am getting ready to buy an ls1 and i went to one of my local speed shops here in birmingham and they told me to stay away from the 99 and 00 because of some oil consumption issues that these engines have. Have any of you guys ever heard anything like this before. If so let me know.

As perviously stated all the ls1's burn oil somewhat. Probably some worse than others, but can be fixed w/ the above mentioned solutions.

My 2000 never burned any oil when it was stock...

Mine hasn't burned any oil either. I think what they may be referring to is the piston slap issue these engines have. Some do and some don't. If the piston is rocking back and forth in the bore, it will have an oil control problem for obvious reasons. Could be other reasons as well,,,but I have never heard of the LS6 PCV valve upgrade. Not to change the subject, but could someone explain this? Larry.

the vacuum on the engines is to strong and sucks the oil into the intake manifold some noticeable some not nevertheless they all do it the ls6 pcv system is a better system to solve this problem my engine does it but very very little look into ur intake manifold i bet its lined with oil

Every 2,000 miles, mine uses a quart. Can someone put me in the right direction for buying and installing a catch can? Where to buy?

I don't have the problem either, but my mileage is pretty low and the car hasn't seen much of any abuse. But the LS6 PCV system has got my interest. I am surprised there is not a sticky with a writeup on this,,,I looked around, for something so common I thought there would be a sticky or something. I am interested in looking at the differences, pics, part numbers and what is needed for LS6 pcv system? Larry.

Hugger Orange- 1999 Camaro Z-28
acceptable oil consumption per GM for our motors is 2 quarts every 3,000 miles
some caddies acceptable is 3 1/2 qts
ls1 are "known" to have piston slap (cold start up), ticking (lifter noise), and some oil consumption
some have all three, a combo of them... or if your lucky like me... none
ill get working on a write up for the LS6 pcv conversion...
one big issue is some 97-00 blocks will need to have some grinding/chunks taking out of them in order for to do the conversion (clearance reasons - LS6 valley cover wont seat)

I hope you mean grinding on the outside of the block not the inside?

Light Pewter Metallic- 2000 Camaro SS M6
107k miles and no detectable oil consumption here (I am the original owner). Perhaps it may burn 1 oz. in 5k miles, since all piston engines have some degree of oil consuption, but it is so small that the level on the dipstick remains at what appears to be the same mark through the whole 5k interval.

thanks guys. I didnt know what these guys were talking about. So that brings the next question is there a better year from 98-02? I have had my 95 for about 6 years and i don't have a lot of trouble with ls1 guys but i hear they make so much more power than you can get with an lt1.
