Good diag procedure. You can pump air into the truck with a gas powered air compressor if you really need to move it by driving to save it from swimming, then fix it later. 925’s are not cheap anymore.

The Detroits have a gear pump to send pressurized fuel to the injectors. They are unit injectors, meaning each of them is their own high pressure pump. There is a restriction jet on the return side to keep pressure up. It is a pretty simple system. Yes, remove one valve cover and make sure...

There are no signs of contact after having installed my plates. I was going to do a valve spring between each bolt and plate to address, but there was another member who saw no contact after doing so as well. The plates are spaced out to begin with (like my sister). Also, with articulation...

Drill and tap new stock ones with a threaded hole to bolt on a retainer plate. Quickly and easily done on a lathe before installation. Old ones press out easily with a shell of an old one. New ones press in by just pushing on the solid center, use lube. I used the shaved wrench, then...

Cute, so what about the ones I bought from you a while back?

This guy for 2020.

Be nice to Will. Replace the engine mount bolts with cotter pins. Throw some more fuel and boost at it, she'll be back out and riding the grass again soon enough. Sexy starter though!

This is a second thread to the already going 8.3L hop up thread. Anyway, our generation (1990) of 8.3's are somewhat limited due to a weaker block deck. It can crack easily, and was later fixed about 1992 or so. The injector choices are easier to come by now, because a lot of shops can make...

Medium and heavy duty engine to trans connectivity typically follows SAE standard orientation. You can nearly bolt anything to anything, as long as it is not proprietary. Some require unique flywheel housings, but still yes. ISL power range is 330-450hp. Externally same dimensions as...

This is like a family reunion. We have Tex, SD, a moderator, and even Another Ahab brought back from the dead and checking in. See, look how excited everybody is about 13 speeds of 400hp ISL 4 valve VGT roller lifter Jake brake power! Gun turret, dump hoist, and maybe I'll be let into truck...

Hope so. I need to list my 8.3L as available commercially, not enough of demand for them here.

20,000lb is set by the hydraulic relief valve in the circuit (1750psi or so). This is why they don’t have shear pins like the mechanically driven winches. I stuck my M925a2 to nearly the top of all six 14.00 tires in mud, playing. Nearest tree was 190’ away. Single line winch pulled it...

Simp, just buy my 8.3L. These engines typically last 400,000 miles or more.

I was going to simply up the power of my 6CTA8.3. Bought a governor spring kit, studied both fuel rate adjustments on the MW pump, bought higher flow injectors with more holes, bought a P pump, drilled and tapped the exhaust manifold for EGT and pressure probes, then before I installed any of...

Cute, but no. ISL will go in once base 8.3L sells.

Tool

Do it. Nothing will break, I promise.

I have the Jake 90 degree handled feeler gauge to loan. Fits ISL, but possibly same for BC? I’d chuck new valves in all holes to prevent reoccurrence. You could be working with a million mile engine. Nonetheless, we are all eagerly awaiting truck of the year to return to stardom.

Posting for potential buyers of M923/5a2 trucks. I was looking for this info when I was buying, years ago. This is the electric oil pressure gauge replaced by a mechanical one, so better resolution. Just snapped this pic 2 days ago:

See, that’s why we get along.
