Suggestion

If it was mine, I'd wait for the snow to clear, drop a few ounces of Seafoam in the oil and run it hard...then do an oil change for the summer season.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I went to top off a little oil and found sludge inside the neck and filler cap. The junk was only near the end of the neck and it looked like melted butter; I didn't taste it to confirm if it was indeed melted butter . The car has been driven 2,004 miles this past winter since being serviced in November and each time it went for drives to get it to operating temperature. I've been keeping an eye on coolant levels since the last service, the dipstick does not suggest intermix and the car has been running great. It has 26,940 miles and 10 oil changes in its life since new. What may be creating this residue and is it anything I need to have addressed sooner than later? Thanks!

POST 2Original post

It's condensation mixed with oil. Normal if you have short drives in cold and damp weather. Nothing to worry about. Should go away after long drive in drier weather.

POST 4 / ORIGINAL POSTEROriginal post

Whew. Thanks Ahsai and Soaringman!

POST 5Original post

Fwiw, this can and often does happen on any car, not just Porsches.

POST 6Original post

A little mayonnaise is nothing to worry about as long as the dipstick is clean. Ken

POST 7Original post

It looks a bit excessive. How's the coolant tank look? Any goo on the dipstick? Hopefully a good long hard drive burns it off. 2003 Carrera 4S Speed Yellow / 1955 356 Continental 1500 Rust Red

POST 8Original post

+1 ^^ It's common, but that seems like a lot of turds in the filler. If it was mine, I'd wait for the snow to clear, drop a few ounces of Seafoam in the oil and run it hard...then do an oil change for the summer season.

POST 9 / ORIGINAL POSTEROriginal post

Thanks for the replies. Fortunately the dipstick looks clear and the coolant level is holding. It has been an extremely cold winter and the 2,000 miles since November is pathetic but the Northeast weather has not been good for cars with summer sneakers! I cleaned everything up and with the weather (hopefully) clearing up it will get out for longer drives than the 16 mile one-way commute to work provides. Here's to warmer temps soon.

POST 10Original post

NOPE! I asked the same Question a few weeks ago and I have run the car and it has all gone away. I rand some BG MOA thru mine just in case but now it is clear as a blown nose
