i found some in my valve covers and crankcase breathers.it wasnt anything to worry about.just assembly lube. hard to beleave its still there at 7000 miles.

 

I believe it is more likely to be moisture from condensation. How long do you run the motor (start to shutdown)? Sounds like it's not getting hot enough to evaporate the condensation.

Unless, for some reason you used assembly lube on the valve covers?

 

now i know why its still showing up....
i pulled the valve covers, assembly oil wont mix with oil , and it built up on top of the covers on the inside. its just still workin its way out the holes
