Cool "Wet" Plugs

2003 Turbo with 87,000 miles on it. 27,000 miles since last plug change. Removed the plugs this morning to install new plugs...threads on 2 were covered with oil. Threads on one were dry on the tip half but "wet" on the top half. Threads on the 4th plug were dry. Does this mean anything?
Thanks!
Bill

P.S. The oil(?) is *only* on the threads...nothing on the tips or electrodes.

If the PT's have individual seals for each plug hole (where the cover meets the head), those could be leaking. I'm guessing here...never experienced this with a PT yet.

But, I did have similar issues with other DOHC engines....

If oil's on your plugs, it typically should be seen on the tips as well.

Have you personally done all the work on your car? Sure it's not just crappy dielectric grease?

Alternatively, have you checked your PCV valve? Oil in your combustion chambers could be the result of a plugged PCV valve causing an increase in crankcase pressure, pushing oil past your rings.. If your PCV valve is functioning properly, you could have one or more worn piston rings or could be your valves.. best thing to do is a compression check to rule either of those out.

Just the easy stuff! Hadn't thought of that!! Maybe that's all it is since the tips are clean.

Yeah...I'll have to check the PCV valve...maybe find someone to do a comp test too. I'm hoping it's just the grease!
Thanks!

Not positive but I think there are individual seals. Hmmm...more research needed...

But, I did have similar issues with other DOHC engines....

it could possibaly be a worn spark plug gasket on the valve cover. oil could just be seeping through and down the tube and as you unthread the plug oil is getting on the plug.

Look down the plug hole and if there is oil then that may be the problem. if you buy a new valve cover gasket you will see 4 circle gaskets, one for each hole. the gasket is easy to replace.

I had the same problem with my 04 turbo, it turned out to be the seals in the valve cover where the spark plugs go in. The oil leaks from the valve cover into the spark plug. I'm willing to bet that it stalls on a foggy morning. Just get a valve cover gasket kit. Make sure you know the engine vin number. Godd luck.

ya know.. my 07 base just rolled over 92,000 miles and it started acting a little squirrely.. about a month ago the camshaft position sensor went AGAIN.. replaced that on my own.. found the one the last mechanic put on to be some cheap generic piece of junk. well afterwards.. car was fine for a week or so.. then started getting squirrely again.. i waited for it to finally pop an error code and took it down to advance auto.. they pulled it.. cylinder 4 misfire. well.. when all else fails.. and it's been a few years and 20,000 miles since your last tune up.. change the plugs lol.. so.. ordered some bosch iridium fine wire plugs.. while under the hood.. found the wires to be brittle as could be (were supposedly replaced by the last mechanic almost 2 years ago) and factory wires.. so a set of bosch premium wires and just to make sure nothing else could go obviously or easily stupid w/ the ignition setup .. i tossed in a Borg Werner ignition coil too.. long and short of the story is.. when i originally pulled the last set of plugs from the car.. i found them in exactly this condition.. after a lot of checking around.. found out the last mechanic to work on the car.. never even bothered to use dielectric grease or antiseize.. instead.. substituted w/ motor oil for the anti-seize and didn't even bother w/ dielectric grease. after a good thorough clean up job and a good 30m of cussing - everything was cleaned up.. new plugs installed PROPERLY, wires, and coil. checked a week later for any sign of oil.. nada.. apparently i just got the 1 jack@$$ mechanic who didn't want to do the job properly. so in my instance, it was a concern but turned out to be nothing. it wouldn't surprise me if the same happened w/ you considering the stunt my last mechanic pulled - seems to be very common.
