Oil on Spark Plug Threads

[wulk025]

So I have oil on my spark plug threads but no fouling of the sparkplugs them self. I also fixed the blue smoke coming from my exhaust. It was my pcv valve gone bad. Now I only have a little bit of blue smoke coming out when I do full throttle. But only for a sec and then it goes away. And when I start her up a puff of blue smoke butt only in the afternoon. Im thinking valve guide seals.

Im thinking your probably right.

What kind'a heads have you got? E7's? If they're stock Ford heads at all, that'd be the first thing I'd check (valve guide seals).

And oil on the spark plug threads isn't a bad thing, means someone was thinking about making the job easier next time the plugs had to be changed lol.

....correction, disregard that last part if there's an abnormal amount of oil on the threads, but if they're not dripping in oil, I wouldn't worry 'bout it
