DOES ANYONE KNOW HOW TO REPLACE THE PCV VALVE ON 2003 F-150 4.6 ENGINE.

 

im pretty sure its look on the valve cover... pull it out of the cover... pull it out of the hose... and push in the new one.

 

Like as decribed above, the PCV valve one of the easiest parts to replace. The location is the passenger side valve cover, towards the firewall. Also, check the hose for vacuum or that might need to be replaced and/or cleaned. GL

 

a PCV rarely needs replaced. just wash it with some brake wash. if it rattles when you shake it then its OK. BTW the cheap metal ones make noise so get the ford plastic one.

 

thankyou
