Coolant leaking into 318 cylinder 8

so this is where you are after you left off here:

nice to know you found the source of the leak.

as to repair... how much work are you capable of? or willing to do? you could sleeve that one hole, but that means a FULL tear down, which in the grand scheme of things... isn't the most awfulest thing around.

as @PRH said, it may be cheaper to have just the one done, but they still have set up and everything else to get there-- for instance my guy charges $80 a sleeve, but that's inclusive to other machine processes already taking place ie. boring, and decking. so you'd have to talk to your machinist about that. maybe they take mercy on your soul (and pocket book).

however, more to the point... it's 60 over and this one is a problem now. who's to say them other sevens aren't going to exhibit a problem after start up, some heat cycles, a few thousand miles, etc.

weigh that against what a reman short block would run ya and see where the chips fall.
