Where is the PCV valve located on a 1994 f150 351cc engine?
I own a 1990 F-150 with a 302. When i had to replace mine, it was hidden underneath intake manifold, so check around there, i know we have have trucks that are 4 years apart with different enginges but hey, maybe you'll get lucky. DIRECTLY BEHIND THE INTAKE MANIFOLD. LOOK AT THE PASSENGER SIDE VALVE COVER ALL THE WAY TOWARDS THE FIREWALL, A HOSE WILL COME OUT OF IT AND LEAD DIRECTLY TO THE PCV VALVE, FROM THERE IT GOES BACK INT THE INTAKE MANIFOLD. CLIMB ON THE FRONT BUMPER AND LEAN IN!
