My brother has a 99 s-10 with 2.2 4 cylinder. On his way home the truck shut off and would not start. On inspection, i had my wife turn it over and noticed the back cylinder was leaking water between the head nut and head. No water in oil (good thing). Do you think the back cylinder busted the bolt and is salvagable? Im going to do a compression check tomorrow to check all four cylinders. Open to all answers! Thanks!
