We have 2 trucks that the bought used and appear to be previously wrecked and deleted by previous owners, so these actually have over 500k on them without throwing a rod. Sounds like this truck dropped a valve or broke a piston ,it isn't good whatever happened to it .I have one more truck to get thru the shop then this one is gonna get backed in , I may end up making a free account with cummins so I can get info .
Sorry I spent the rest of the afternoon getting my limited free account on quickserve going and reading the engine manual. Here is a picture of the injector on affected cylinder that clued me off to keep digging.
the more expensive the part is that’s broken the more revealing it is.
I looked at everything with a scope even down into the cool side of charge air cooler ,i think that piece now pieces of steel was either left in intake side somewhere on accident and it finally got into engine . Thats all I got for now till head comes off ,hopefully today.
I'm also not getting paid 165 an hour to do the work ,bosses cost saving is gonna be a bunch of new hardware and at least a new accessory mounting bracket. Im probably gonna end up doing an inframe with a recon head. I need to order up a couple tools for reassembly. It should be a million mile engine like when they first came out cuz there are various bits and bobs plugged.
Yes, and I also believe the entire front structure must come off? We had an ISX that needed front structure resealed, luckily it wasn't the head gasket, which can produce a substantial oil leak that looks like the front cover, FWIW. The bill was $4400, and we were told if the head would have had to come off, it would have been 50 hours of labor instead of 30. The Cummins ISX has to be, without a doubt, the most perfectly designed money-maker in regards to service in the history of engines. Change my mind...
