Rebuilding a 2350

[Waterloo]

No clue what motor you have, sounds like a 2250 or 2350, but... Ha Ha, just saw the header... 2350 it is...

MAKE SURE the BLOCK IS MACHINED! If the block is not properly cut to hold the liners you are pissing away your money. Set the liner heights to .014 of an inch. And if they say they cannot do it, take the truck to Mr Hagg! I would go see him for this in frame anyways, I would not let anyone else in my motor down here in the states. And if they can cut the block for liners, I would be standing right there to view the measurements. I mean RIGHT THERE over the guys shoulder. Trust NO ONE!

I would also replace the oil cooler, those do fail in time, you are in there, replace it. Sits in the block behind the EGR Cooler.

The turbo, if it is still nice and dry, I would maybe pass on that for now. When the time comes, YTS Turbo down in Griffin GA can get you a nice and professionally remanned turbo for half the price you will pay for a Cummins reman. These Cummins reman turbos have been of very questionable quality as of late. I had two of them on my truck, neither lasted more than a few days before puking oil all over the place. The YTS turbo has been rock solid, knock on wood. I was just in there inspecting it, still nice and dry and working properly after a year plus of service.

Is there something wrong with the Jake solenoids? If not, I would leave those alone. Mine are original with over a million miles on them. The Jake harness, I would replace that if it looks toasty. Also replace the cam and crank sensors, inexpensive to do.

If the cam and rollers look good, leave them alone. They are not that difficult to replace if need be down the road. Keep the oil clean, do not abuse the motor, and a million miles plus should be doable on those.

I would do the motor mounts, cab mounts, look around for other little things that are soon to fail. Most parts are good for around 800,000 miles, like the ECM.

And I would go through the fuel pump, rebuild it or replace with a new one.
