Odds are in favour of the engine failing again (chewed up cam, gears, or crank, spun bearing, excess blo-by, etc) if it even survives this.

When mr. hag's shop gets one like that, even if the engine can be saved, it takes flushing the engine block at least 5 or 6 times with a mix of diesel fuel and oil +++ replacing all the crank,main bearings, replacing the oil cooler with a new one (you just cannot get the shavings out of it properly), and giving everything else a thorough inspection. -Even if it can be saved, that engine is going to have a short life before cam goes out, rockers start going bad, and all sorts of other issues.


Maybe he (mr. hag) can chime in and give some more detail if he gets a chance. He has had to try and save several of them when that pump fails.

BTW: That pump definitely was original .... still has the old ceramic style plungers in it and those type of plungers, the material that flakes off is severely destructive and almost impossible to get out of the engine, where it will continue to do damage even after all repairs and flush, etc.

Also, there are other concerns on the truck that were mentioned ... don't forget to go back thru this thread and take care the things I mentioned about the electrical system regarding the J1939 and such. As well, it needs a decent de-mandate program in it that is not destructive to boot. Thankfully it is a 2250 so you can do this part yourself (via the free version of africa-G overlay/program)... just send a copy of whatever your going to put in the ecm to me for review and update it to ensure what was done is safe and correct for it.
