hey my freind has a bad pcv valve (computer read out says its reading bad) on his 97 Mustang. i know this is a truck place but the stang site hasent helped much. i need to know ware it located and how hard it would be to replace. thanks

 

No Problem

Normally they are located deep within the engine near the crank fribulator orifice and cost about $4200-$5000 to replace. It stands for Poly carbon Venalalinine. I wouldn't try this if I had never done it before.....

Sorry, I can't do it. just kidding....

They cost about $4 and are located on either one of the valve covers. They plug right in the top and can be changed in about 10 seconds.

 

My 5.4L is on the passenger side valvecover about 1/2 way back.
