Pcv

Recently did a 98 and a 99 blazer intake. After all runs great except get a PCV vibration noise some times from both. New PCVs didn't help so think it may be the rubber grommet is too loose. Anyone have this happen to them and find the fix, thanks.

Update- Yes, after the intake gasket I did, the throttle cable plastic little push pin to hold the cable to the intake bracket was broken and causing the noise with the PCV vibrating against the throttle cable. Secured with a nylon cable tie to the bracket - Quiet again.

Really made me nuts after the first few changeouts-A new one would stop it for a while- but back to the same annoying rattle.- Came to find out that the hose running to the pcv was pressed up against the throttlr cable bracket. A piece of foam tape later--2 yrs with no rattle. Good luck!

Also I have used some black electrical tape around the PCV to make it fit tighter before.
