hi all
Just picked up a 1993 4.2 diesel gq for $1000 it is good nick with less than150,000k's.
Problem is it has a stuffed head on it and has been standing for about a year with a sump full of water and old oil. Luckily the guy who owned it was smart enough to remove the injectors and the injector pump so they are ok. have picked up a good head for reasonable price. once running what is the best way to flush the motor out ? got my doubts about engine flush you buy at the garage.
old time mechanic says fill sump with diesel run for a couple of days. that will clean all crap out of motor. but i don't know about that one. any comment would be appreciated.
regards
al
