SUSTAINED BUDDY! Say like 6 miles up a mountain at 65mph! pulling 18k! Always waited for the pop or boom! I'll be interested to see the piston tops!
I have one that'd need a quick hone and if you're going to do that, just as well put some machined cap 12/24 valve rods in it, too....Anybody have a useable 6.7 short block?
Sustained 1400 is a lot different that a short run over 1400 lol
Still not a big deal, lots of Cummins factory cals will do that.
But if it's pin holes from cavitation. You won't see them at all.
These are liners I pulled out of a Series60 for that exact problem. Unfortunately you don't have liners. So you'll never see the backside cavitation damage.

Well I got the old motor pulled apart and the pistons were fine! The head not so good!
So in conclusion the motor can run 1400 for long periods BUT the head pays the price!
It was cracked so bad coolant was leaking into the cylinders.
