Yellow Jelly inside Oil Cap? - WTF!?
Discussion
Just gone to add a little Mobil 1 to my Boxster (six months old 2.7L 987).
The inside of the filler cap and the bottom surface of the neck of the filler had this strange kind of yellow jelly like substance on them.
Does anyone have any ideas what on earth this might be?!
I've always heard the term "Mayonnaise" when referring to head gaskets and I wouldn't say this was anything like that but naturally I'm now shitting bricks in case it's something really bad, though I don't know why as the car's obviously under warranty.
TIA

Don't panic, this happens to the 996 as well (from my own experience)
I thought I read somewhere that a bloody good thrashing helps reduce it - not sure how or why though!

Cheers that's put my mind at rest, and I've also done some Googling and found similar stories on Rennteam and other Porsche forums.
Take a look at your coolant. Has the level dropped unexpectedly?
Look inside at the fluid to see if it has an oil sheen, or a mush. Check for mush on the dipstick too, but do consider that if you do repeated short journeys you can see this mush due to condensation built up in the engine. Chances are it has none of these things.
I have found with my 996 that some moisture (white mush) appears when the weather is moist, but through a dry summer there is nothing. I have done as advised by others on here and wiped it out occasionally, hence my observation as to the weather. The long oil fill neck provides a nice cool place for any moisture to collect.
At least this is what I have observed with my car over the past 18 months, and it seems fine. It is a well known phenomenon and likely nothing to worry about.

Tbh I have no idea how to measure coolant on a 987 - I didn't think it was possible without a set of ramps/access hatch/tools etc?
The car drives perfectly and all temps and lights and levels (according to the onboard computer dipstick) appear fine, it literally just spooked me when I came to add a little oil this morning.
The only reason for adding the oil is that the level seems to be showing as one level from the maximum and I know they will drink a little oil especially when newish/running in so it was just a 400ml top-up.

Does no one read manuals any more??
Uncrew the coolant cap and look in it.

Hands up that's plain embarrassing tbh
I'd assumed the coolant was like the Oil, electronic other than a top-up flap it didn't dawn on me that you'd be able to measure the Coolant via the flap but not the Oil.
Scary thing is I do read the manual, or I thought I do...
Well 5 days a week is usually a 20 mile each way commute, mostly dual carriageway with a little town at one end.
I suspect as others have said the length of the pipe from the engine to the filler allowed some condensation to build or something, I'll keep an eye on it though.
Thanks for all the replies.
