Isx15 randomly shutting down

[mikkhh]

Oh well reminds me of guys around here with their mid stop liner engines that are closely related to ISX. Instead of owners trying to think why they have countless number of failures again and again they just start shouting and arguing, zero actual arguments from their part.

Lots of guys are "fixing liner seals" issue (external coolant leak from head gasket(s) on exhaust side) using some mounting paste and new liner o rings. Those repairs do not last long, guys keep saying that blocks are warped, that is why their repairs are not lasting. When you ask about liner protrusion they repeat their warped and bad block nonsense crap. I have one engine with me for investigation that has failed less than 600 miles after liner seals changing. Head bolts are old with no punch marks (repair manual on those allows to reuse head bolts along with rod and main bolts for 3x times after the initial use, punch marking when reusing). This engine under investigation is made in 2007...

I even asked dealerships of that engine/truck manufacturer that I would like to bring you engine block with liners for cutting liner seats, since repair manuals mentions tools and things how engines should be repaired and dealer should be able to set the liner heights. They refused, only way they are going to do the job if complete running truck is brought to them. It makes no sense to me, I would instead just tell that we will agree on machining specs and that is it, will measure on site and after that no warranty or any liability besides the fact that machining job was done correctly. They could charge 100-200 per cylinder to cut those counterbores. Should not take that much time? But instead the dealer is telling me too that blocks could be warped and then must buy new block...
