 Subject: PCV noise/vibration
IP: Logged
Message:
I tuned up my '99 3.9 yesterday, new FR5 plugs, summit 8.0mm wires, brass cap and rotor and pcv valve. I noticed yesterday and again today that there's a noise on the passenger side like a swarm of bees that I haven't heard before. I isolated it to the pcv...the pcv and hose is vibrating. I pull out the pcv and there's a ton of vacuum. When I shook it and stuck it back the valve cover, it stopped but started again when I revved the engine via the throttle cable. I don't recall this noise from the old (original OEM) pcv which was pretty oily. Did I get a bad one or is something else going on? Or, is this just normal. I don't recall pcv noise in all the other cars I've owned so this is new to me.

Where did you get the PCV valve at? after market valves are made to work with more applications and many wont work proper in Dakotas. Put a dealer PCV in it.

I got it at Autozone. Can't remember the brand but it was the only brand they had.

Got to the dealer today and picked up a new PCV valve. It cost about twice as much but works much better!
Thanks for the help!

I have had a PCV valve separate into two pieces when I tried to remove it from the valve cover. Autozone generally carries crappy parts these days. I prefer NAPA and Advance Auto Parts for aftermarket.

Some time ago now, I bought a $2.50 PCV at O'Reilley's and it sounded like I had a hornet's nest under the hood. Went to the stealership and bought one for about $6 or so and no more noise. Some things are just better purchased from the dealer.

Hey Guy's, I never heard of a bad pvc before, but I guess we can learn something new everyday.
Other than being clogged up, never heard of the problems that KCWW was having.
Thanks for sharing the info.
Good Luck to everyone,
