Wining sound f250 sd 5.4 1999
Wining sound in truck. Sounds like powee
steering but is definately not. Was told to
change pcv valve any rhoughts
The PCV in the 5.4? made no change? Pitch of the whine increases with the rpms and eventually goes away. Regards
It's the hose that runs from pass. Side pcv to back of intake by firewall it's either cracked on rubber hoses or off
I am a 15 yr ford tech by the way Good luck
