A question that I am not sure how to even ask...

I suspect DC is pulling your leg. 2 days and no answer? It isn't that hard to unscrew the drain plug. Even the title sounds like a come-on. Maybe I'll try posting this on a Chevy site and keep them waiting.

Sorry for the confusion, but I noted in my first posting that I'd pulled the drain plug before posting.

The delay has been to work schedule and good weather for the valve cover...
