Oil in spark plug tubes?

Had the car up today and did the plugs. When I pulled the coil packs there was oil in the tubes. The car burns no oil and the plugs are dry. Anyone know why the oil got in there? Am I looking at a major overhaul or just the nature of the car? 98 boxster and thanks fir the replies. Gb

You engine has plastic plug tube with O-ring seals at both ends, which tend to leak over time and require replacement. Do a search, been covered several times............

I don't think it's totally unusual or signs of catastrophic engine failure, but I'll wait with you to hear from other owners with more information. I'd like to know myself.

The plastic tubes crack and the o-rings lose elasticity. Get a set of tubes and rings, replac them all, and you are good for a long time.

Who needs more car owners to comment, JFP knows his $hit better than 99.9% of owners and most Porsche mechanics.

It looks like everyone is in agreement with JFP.

JFP is an amazing resource. His input is truly appreciated. Perhaps you should PM directly if you don't want to hear from others.

When you buy replacement tubes and seals- buy from a reputable source . As JFP and I have discussed and quantified, some aftermarket tubes are out-of-round and some seals(particularly the inner ones) are off- spec. The out of round tubes will never work well with any seal !
