I had a driver call me and tell me the truck was running rough. I had him drive it home so I could see what was going on. Opened the hood and there was oil over a lot of the passenger side engine compartment. Checked oil level and it was fine. I drove it to the dealer ship and had the codes checked. Told me it was P 2063, P 2066, P 2069, and P 2072. Cylinder 1 2 3 and 4. Contribution fault on all. Pulled the number 1 injector and did a compression test. Low or no compression. Had them scope the cylinder and found a cracked piston. My question is this. Do I have 4 cracked pistons? And what could have caused this one to crack. I have a basic understanding about diesel engines but I'm no mechanic. Any ideas would be greatly appreciated. The truck is a 2011 LML with 172,000 miles on it.

With 172k on it I would replace the pistons with some of Fingers ovals or at least Mahle race cast... Is the truck deleted and tuned?
Sad fact is the D-max has weaker pistons in the later models, 06 and up.

Yes I had the DEF and the EGR deleted. Only had a 50 hp tune done because that was the lowest they could do. Truck has plenty power for what I haul with it. I don't need massive horse power. Just enough to make a living. What I'm trying to find out now is what caused the piston to crack and if it is just one piston should I change just one or just get a bare long block and go from there?
