When the water gets whipped into the crankcase oil, it turns into a pudding-like consistency. As you drive and heat up the engine, the heat evaporates the water from the oil. Since the oil filler cap is at the top of the cylinder head, the oil/water settles in the oil cap, forming a yellow gunk.

Why is my oil cap so hard to get off?

A layer of burnt oil forms on the cap that makes it hard to remove.

What happens in some cases, is the mechanism can fail (stops ratcheting) and the cap gets cranked on.

Once I removed the oil filler cap and it was like an ice cream with a massive dollop of the stuff. Clean out as much as you can get your finger into and take it for a long run (hour+) and it will clear up for a while. Of course it just comes back again when returned to normal use.
