Oil in spark plug holes?
My 2001 F150 had been having a slight miss at low throttle when climbing a steep hill. It never was bad enough to set a code, so I figured I'd just order a set of the Global Automotive coils off Ebay. That would be cheaper than paying the dealer $150 to tell me which coil was failing. I thought I'd do the plugs too, and it turns out that it still had the factory plugs in it! 210,000 miles on the plugs! :eek: Anyway, I've got the new plugs in, torqued to 14 ft. lbs. per the Haynes manual I've got. I still need to put the coils back on the passenger side. Thanks to the very helpful tips on here, the job really wasn't half as bad as what I thought it would be.
But here's my question: There was oil in three of the four plug holes on the passenger side of the motor. It looks like a valve cover gasket leak to me, but I asked a mechanic that I've had do work for me in the past, and he said it was probably a bad head gasket. $800 - $1,200 was his estimate. I've looked the motor over, and for the life of me I can't see how a head gasket leaking oil, would end up getting oil in the spark plug holes? Is this possible? From what I can tell, the plugs are well above where the head meets the block. Am I wrong?
Thanks for reading.
