Hi all,
Just checked and topped off oil (Mobil 1 0W-40) and I found water droplets underneath oil filler cap and inside the fill tube also see a creamy yellowish weird residue as well.
Just came back from a 700 mile trip in VA. Car seems to be running fine.
Any thoughts as to what is happening??
Thanks a ton

I had that yellowish curd looking residue too when first picking up my new C4S. But after 500 miles or so it all burned off like my service advisor said it would.
Said it was condensation from the number of short start and stop driving they do with new cars coming out of the factory to get on truck, on boat, off boat, on truck, etc.
Whoa! This is really, really weird. A good friend of mine called me about this very subject and he has the same exact car as you do! WOW! Small world.
Yep, it's normal.
They call it mayonaise....entrained water vapor that boils off when you drive it hard
Mostly seen in the winter months or by old ladies that own performance cars
Thanks all. Oil looks normal, smells normal. I don't dive the car that much, but thats all changing. And the 700 mile trip I recently took was the longest I think I have done. Car has 6200 miles on it now and runs fine. I will change factory oil this week.
Hi, I have just joined and am about to take delivery of a 06/03 C2 with 7000 miles on it. Found the same dijon mustard inside the oil filler and walked away from the sale - an official Porsche dealer (UK). This will be my fist Porka. Now find that this seems to be normal, hope everyone is right!!?? Adrian996 (UK)
If the car is not used much and for not long periods and not always brought up to full operasting temperature for some period of time - water will condense in the oil and not have enough time to boil off in normal operation. Also a common occurance on light aircraft engines they are cold soaked with moisture in the air and then warmed. The water vapor in the cold air condenses into water drops and then -- if you keep the engine at operating temp for a sufficient amount of time the water will all boil off and vent out of the crankcase. If not, you've got water drops in the oil.
If it's sitting for any length of time (especially in cold, moist air) then when you start it, make sure you run it for a good length of time at full operating temperature.
I see this regularly during the cold winter months up here in the NW but not in spring, summer or fall. My shop said don't worry about it. It burns off.
