I wonder if there is a way to run the oil pump backwards with a drill and feed it the kero from the filter boss?? The “reverse flush” method; just a thought. Keep us posted...
I know someone who did the "reverse flush", So far that engine is still running. I recall he made up some adaptor to the oil filter so the cleaner got through.
Best to pull the pan and scrub it out. You will get all the crud out.
