As many of you know, the PCV system on the 98-02 LS1’s isnt exactly the greatest system on the planet…..burning up to 1 quart every 3K miles. After many complaints, GM finally issed a service bulletin to address this issue on all of the GEN 3 engines. They have replaced the ball-type PCV valve with a new fixed orifice design that is used in the GM trucks. This design will help reduce oil-consumption on your LS1.

cheap, quick fix to the oil consumption issues we have with our ls-won’s ;P hehe.
Be nice to your engine and don’t forget to ALWAYS use synthetic oil, it REALLY helps with burn off…

This Pcv works quite nicely, other than the noisier sound you get with the fixed small diameter hole instead of the norm. I have modified my stock 1999 to use this pcv valve with it in a vertical position. All u need is a old 90 degree spark plug boot and some 3/8 hose. This helps a lot with keeping the oil down but use a catch can when u can afford it,.
