Cracked Pistons

[andrewsw]

I will make this short; at 73K, my dually ate the number 3 & 4 pistons. I was doing 55MPH steady speed, hauling 10K lbs. trailer and hay, EOT of 203, 20lbs turbo. Apparently the harness for the glow plugs came out which accounted for the flowing oil but only damage to motor was cracked pistons. I had a blown headgasket repaired at 62K, EGR & valve removed, spartan tuner running 300 LL tune. The mechanic only wants to replace the two pistons and I need advice. As I am paying for this fiasco, as well as already paid for the headgasket repair, I need it done right but just put $17K back in April so not exactly flowing in cash right now. Thoughts? Two pistons & rings, two pistons with rings all around, 8 pistons & rings, short block. WHAT??

REPLACE THE PISTONS! Dont buy a new motor or replace all eight. Tripple check by taking a compression test and make sure none of the other ones are damaged. And have the mechanic drop the 2 bad ones and put 2 new ones in. If you need help with parts let me know!
