Pulled out the pistons to do a ring and valve job this morning. For those of you who have never pulled the access pan to pull the pistons, mine were full of grease but fortunately no metal parts or missing pieces. Now to clean and paint
When we took our 19 out of storage after sitting for 45 years I the drained the oil and then flushed the crankcase with kerosene two times. I let it sit for few days each time I did it.
Then I jacked the front of the car up so most of the kerosene drained out and flushed it again with cheep motor oil.
Dave, is this something you've been running or just picked up? What does the transmission area look like when you remove the cover from the hoghead?
Is that coolant in there?
I was going to say that it looks like a little water mixed into that oil.
As long as you have the inspection plate off, reach into the pan with a rag and wipe more crap out of the crankcase.
My first thought was coolant in the oil too.
I agree with Erik here - if there is that much crud accumulation in the dips, there is surely a considerable amount wedged next to the lower cover retainers so you should remove those and wipe the inside shelf down - clearly neglected !
