I just replaced my PCV valve and WOW it takes longer to get the new vavle out of the package than it does to get the old valve out of the UIM. Cool! I've read that 92'* didn't have PCV valves. What do you do if you have a 92? Do you have to swap the UIM with a 93 and up one?

92 does have a PCV. I've done my 92 L67, my parents' 92 Olds 88 L27 and my brother'* 92 L27.

Oops, sorry, my bad. That'* no EGR valve.

Some 92 L27'* do, and all 92 L67'* do. 92 L27 egr'* are few and far between, though.

Gotcha.
