So I ended up with a few extra parts from a friend that bought a ls1 crate engine and was wondering if this is the newer style/ls6 valley cover. If soo what all parts do I need to swap to my 02 z28 and while the intake is off what to replace since it has 100000 plus on it. Thanks for the help

 

thats the old style

 

you can tell the new style by the holes in the bottom

 

at least it was free

 

 

the new style does not require a PCV valve.......its worth it to upgrade IMO

 

thought i had a winner just have to keep searching thanks for the pics

 

Nothing wrong with the old style you just have to run an external PCV.
