who is right about the location of the pcv valve

[chevysrule]

I really want to change my pcv valve but no one seems to have the same answer on where it is located. The haynes manual doesnt tell u anything ! my car is a 1990 3.1litre v6 automatic! and im candain, dont know if that makes a diffrence or not but i really need to locate this thing.... i am planing on changing the spark plugs at the same time


thnks in advance

I'm trying to remember, and it seems like it is up under the upper plenum, if you look from the backside with a mirror, under the plenum, you might see it. Then you gotta figure if you can weasel it out without major surgery.
