What exactly is the difference between the PCV valves in a LT5? When I replaced mine, I used identical valves thinking that is was merely a volume issue. Is it a vacumn issue, or a "timing" issue, or something else? I tried to search for "pcv valve", but it didn't find anything.

they open a t different levels of vaccume.if you notice that one spring is lighter than the other . to give a broader range of vaccume. not much space in the bottem end is my understanding. i also found on my car i used lessoil when i revrersed the pvc valves.it could be that the car is a little strange like its owner:mrgreen:

I wouldn't be sure the one's I pulled out were originals. No numbers on them.

Car doesn't smoke (except for the first ten minutes after I put the PCV system back together), now I'm wondering if I did something wrong.
