Or, drain all the oil, dump about 3 gallons of warm kerosene in the engine until it fills up the whole thing. Let it sit over night, drain in the morning.

Thanks for all of the replies. This car has turned into a valuable learning experience and couldn't have done it without the guidance and feedback. I will definitely change the oil after 100 miles. Should I change the oil filter again?

Not sure if I will keep this car, but I am curious about filling the engine with kerosene Mike. Will the kerose dissolve the gunk? Also, would I need to drop the oil pan to clean deposits? It there a screen on the oil pump pickup tube that may get clogged?

Again, thanks for the discussion.
