i also changed my pcv valve to a nissan one. i took the hose off and noticed
a few things. the nipple on the intake manifold was filthy with oil residue,
the hose itself---, i washed it out and blew air into it to dry it inside and
dirt shot out. i sprayed oven cleaner in there and did it a few times to get
it somewhat clean. even tried q-tips and the damn dirt kept coming. i think
im gonna have to try some combustion chamber cleaner if the pcv valve was
this dirty. what ya think - especially you ken, think i should do what you
did.later tony
