Ford Repair: Ford F150 302 Engine year 1984, compression rings, pcv valve


Question
Leaks at front and rear intake, Shows oil in air filter cover. Oil in air filter cover, could this be from leaks at intake or could compression rings be worn.

Answer
James-

  I'd try changing the PCV valve first.  If the PCV valve is clogged then the crancase can't vent excess pressure and it cause oil to back up past the pistons and into the intake...sometimes even to the air filter.  Hope this helps.
