gents,

I was going through my electrical/charging systems after picking up this project within the last few months. After i tested the batt., alt, and replaced the starter i changed the plugs. cylinder 5 and 8 both had oil and charred oil on the threads and surrounding the base of the electrode. I am planning to perform a compression test to see if it is the rings, but a friend said it might be the head gasket or the valve seals.

I checked the coolant and oil and i didnt see any real noticeable mixture/ milkyness. my question is what should my steps be in determining the problem, and is this a time where the top end will need to come apart and i should think about doing a rebuild?

any advice/ideas are welcomed, I am not very knowledgeable on this subject of how the oil gets to the plugs.

wrong plugs for your car
your probably have bad valve seals/guides/rings. Any one or combination.
You likely have a stuck PCV which is sucking oil into your upper intake.

Solution: Install Autolite 25 plugs, run a full compression and leak down test, replace PCV valve and oil screen.

Ford does not like the Bosch plugs,.

Thanks to all so far.
Adder: I was switching out for the Autolites when i found the oil. these were the plugs installed when i picked up the car. I will search for a thread on PCV valve and switch that one out, and run a compression test once i can get one from an auto store. i will keep posted.
Adder, what do you think of an additive like MJR suggests?

MJR was more likely joking. That amount of oil on the plugs, you have a sealing issue somwhere, whether it be rings or valve seals.

i thought so, well i pulled the PCV valve while im debating just buying a compression gauge rather than continue waiting to rent one. the valve is a motorcraft and is still rattling. the screen as pictures below is pretty dirty bottom side. I tried to spray out the screen (no avail) and it probably just needs replacing. no dripping oil from pcv line either.

Project 5.GO!

Hose it with easy off oven cleaner, take a toothbrush to it, then shoot it with the hose. Wear gloves, and watch the brush doesnt sling the crap in your eye. I did it inside of a mostly sealed ziplock, which served as gloves and eye/clothes protection all at once.

sorry , couldn't resist...been waiting to post that pic for a while........you can do one of two things op.....rebuild it or run a hotter plug to burn the oil...don't use platnuims, use a standard copper core resistor plug, such as an autolite and monitor oil consumption to find out how much it uses.
