I’m watching an old episode of Wheeler Dealers where they work on a mid ‘70s 911. The owner of one was telling Mike what to look out for, like if you pull off the oil cap and see white stuff, meaning a blown head gasket. Re ally? I always thought that that white gunk was a mixture of oil and coolant, so he’s saying that the mixture of air and oil will make the same mess? I’ve n ever heard that before, although I will admit that I don’t have enough experience with air cooled cars to know what the oil looks like when you have a blown head gasket.

That can happen is you regularly run your car for short periods of time without the engine getting up to temperature . It’s just built up condensation that doesn’t get burnt off.
I had a fright with my Galant VR -4 when I have soupy gunk on my oil cap. But I regularly drove it just a mile or two, in the dead of winter like -10 to 10 degrees f ahrenheit. Once I gave it a good long drive properly heat cycle the engine it went away.
So it doesn’t always indicate a blown head gasket, you should drain your oil and have a look at it for that. But the mixture of oil and air thing isn’t right either.

F
ailed head gasket allows oil to mix with coolant. Or combustion chamber to mix with coolant.

But on an air-cooled engine?

clearly sabotage! (Never seen that in an aircooled vw... but admit I don;t have any experience in ones that are hardly ever driven.)

Yeah, it’s not a good thing regardless, but you definitely can get water in the oil without coolant.

It can also be a sign of a blocked pcv or a dri ver not letting the vehicle cycle to operating temp to burn off moisture .
