just looking at it bare eyes no dial indicator. That’s funny. Can Superman even see a half a thousands difference between holes. Most machanics can’t do the math to cut counter bores. That’s why there machanics. Cutting counter bores is a little beyond the normal shop. Only the best are gonna do it. I just had a Cummins reman that had cracks in the counter bores. It looked to be put together that way.

I had to deal with a mechanic just like that if not worse.... trust me, take it somewhere else my friend. You can't trust ppl that dont want to do what they are getting paid for, the mechanic that i had my at truck. ppl were telling me he is a great guy and mechanic... not so much of ether to be fair and honest. He told me the didnt need to cut the counter bores. absolutely refused, but everyone else could clearly tell what is going on. Hopefully you are in a better financial situation then i was when i got here, i pray it all works out for you!

I’ve seen some with cracks between valves and a couple times at the injector hole, but all had over 500k miles on em. Maybe improper torque sequence or maybe debris on the deck surface?

I've seen plenty that had cracked, like you said, usually between the valve seats, or between the 2 exhaust valves after high hp horrible (big-name delete tuning) programming was installed.

Even saw some pictures of one that the deck was not cleaned properly too. The same hack-job idiots used some kind of rtv on the chineese knock-off head gasket to boot.

I think even snail-express lost an engine (not the head though) due to some morons using rtv where they shouldn't have once -- could have very well been the same outfit.

You like to put some salt on wounds :big_smile2:
