			| Hi Sambas, 
 I went to change the oil in my beetle today. (It's fuel injected if that makes a difference.)
 
 Everything went as normal until I took off the oil fill cap. The inside of the cap and the top of the fill tube were coated in a weird light brown/beige creamy substance that looked like pudding or yogurt.
 
 I wiped out as much as I could get using paper towels and then finished the oil change as normal. The car runs fine.
 
 What is this stuff? Does it indicate a problem? If this was a water cooled engine, I'd be worried about oil and coolant mixing but there's no coolant here to mix.
 
 I'm worried. Help appreciated.
 
 Thanks, Sambas.

			| Blown head gasket. That's water from the radiator getting into the oil. 
 No, really it's just condensation. Happens when driving the car not long enough to get warmed up.
