Why does my oil cap on the 2.8 have a white gooey residue on the top?
I also pulled my dipstick and there was a drop of white goo on it too. Is this coolant in my oil? If so what can i check to find out where the coolant and oil is mixing.
My coolant resivoir tank is totally clean. So it does not look like there is oil in the coolant.

It might mean you are either:
1. Not doing frequent oil changes
2. Doing too many short trips and the oil is not heating up enough
I would run a can of oil detergent about 300 miles before you next oil change.

Posible blown head gasket
An opening between an oil passage and a water passage at the head gasket can let coolant water into the oil creating the white-tan goo that you see on the oil cap.
