Surprised Cummins used only 4 head bolts per cylinder and all that chain on the front of that engine is crazy.
Huh, did not catch that. Good eye. As for the head lift issue and popped gaskets, it was my understanding that occurred mostly on deleted and tuned vehicles. Haven't read of a head gasket failure on a 13 and up stock truck or many other stock 6.7 engines from previous years.
For chain drive, makes sense for overhead cam engines. Just about all overhead cam engines are chain driven, and given the lower operating rpm of a diesel, it will probably last a good long time before needing service. I do prefer gear drive though. I'll download an owners manual as soon as they come out and see if it is a service item just out of curiosity.
I'm more concerned what the oil dilution (especially when running bio diesel) will have on the long term reliability of the chains and the plastic tensioners.
