I’ve got a 91 e350 short school bus with 7.3 idi and after doing a whole new cooling system I find water getting into the oil, so I’m guessing it’s got a cracked head ? At this point I want to take the engine out and go thru it, id much rather swap a Cummins and different trans but just more money
Yes it’s most likely a cracked head, taking them both off and getting them tested and freshened up will cost you $600-1000 or you could just find another 7.3idi for the same price. Cummins would be nice but your looking at $1,500 for a running VE pump 12valve to $4,000 for a good running 12valve with p-pump
