Scored Main Cap Bearing - Ouch
The Amsoil is for deposits, not what I want. I have some diesel here for my truck, how much do I add and how long do I run it just to get warm then dump it. Do I need to change filter before the next flush, then do it again. The material I am sure is the copper left over from the previous disaster. Analyzed is a good idea also. a company. What about ATF? I contacted Rislone to see if they had any ideas?
If you insist on the flush, I have flushed with diesel but not running.
I am NOT recommending you use diesel or kerosene running. I really think you should just use it as a 'wash': pour it through, and let it run right out, to try to get out any stuff lying in the heads, and pan.
If you want to go hard-core with this: I actually put a full load of diesel in an engine that had coolant in the oil, and them primed the engine with diesel, while slowly turning the engine over and over by hand, to get it to go everywhere. Drained and repeated with diesel. I also pulled the lifter one at a time while doing this, starting at the one closest to the pump, and also tapped the lifters to get the old oil and junk/coolant out of each one. Then drained the 2nd diesel load, put in cheapo Walmart thin oil, and then re-primed for a while, while slow turning. Drained and primed and turned again, with a new batch of cheapo oil. Then drained that 2nd batch of thin cheapo oil, and put in a 10W30 Walmart oil, reprimed, then idled 'til it was warmed up, then drained and put in another load of cheapo oil, ran and changed that oil after 10 miles, and finally put in the oil I wanted. IMHO, oil is suuuuuper cheap compared to the time and expense of this engine work. (BTW, this process worked
really good to get the coolant out, which had gone everywhere.... but then I found a massive head crack LOL.)
But I am really questioning if this is necessary in your case.
