What did you do with your GMT400 today...or yesterday....

That guy makes his $$ rebuilding engines or selling new ones. When someone wants his shop to swap engines only - he gets labor but not the $$$ selling one.
Not buying a used engine is same as not buying a used vehicle: if you buy a used car you bought a used engine, used transmission, used drive axles, used steering & suspension system.
People who don’t know anything about cars often get ripped off buying used.

The thing they demonstrated that was so worn out in that used engine- truth is if a guy with an automatic transmission put that engine in- the worn thrust bearing would stop wearing out so fast and might last a while, but I doubt it because to wear the thrust bearings that bad usually takes over 250,000 miles closer to 300k is my real guess.
What else is gone by then? Equal compression. Hence the advice to do a compression test before purchasing

I was give a case W9 loader. Engine was seized. Pulled injectors, knocker loose into each cylinder. It tirned over a 1/4 turn after about a week.
Its a four cylinder.
Valve stems is rusted into the guides.
I got back to work and never had a chance to finish getting the hood removed(cab and fuel tank filler is holding it from sliding back far enough) so to get the rocker covers removed.
I have a few days off work now so hope I can get back out there and see if them valve stems can be gently made to move.
That was the problem @dbrannon79 s engine

Put the new brake drums on today and braking is back to normal. Will take the Suburban over to our local mechanic to have him install the ABS Modulator Pump and work through the transfer case shifting.

Eagle Watch texted me that I blew the fuse to the Transfer Case Control Module, so that is back to the before scenario with 2Hi, 4Hi and AWD all working, but still no 4Lo. I have two brand new AC Delco encoder motors, but they are set to neutral. Transfer case will not go into neutral. You have to move the shift shaft slightly to get the encoder motor installed, but once installed it just grinds on the parking pawl in the transmission and no go whatsoever. The old encoder motor does not do this, but it does not get me 4Lo. Would like 4Lo, but it’s not a deal killer.

So he’s down to installing the reman ABS pump module and getting that working, which will be nice. I did find the ABS pump module I harvested from salvage on the shelf in the Fullerton garage. Turns out it’s not the correct ABS module for the K2500 as they are specific. However it was the pump that was bad on my existing ABS pump module and I’m betting that pump is agnostic to truck model. In theory, I could swap that pump onto my old ABS Pump module and have a second back-up unit. We shall see.
