Question Tinindian,
I didn't and hope not to have to pull the engine totally however I could only get to the 4 freeze plugs on the sides. after removing them I can see " lots " of rust particles, ( Small a large ones ) so can I vacuum them out or brake down and do a total engine over haul at this point. I did get it started and running before I find water in oil pan. Your thoughts would be greatly appreciated.
