Just to let you know what happened with the vehicle, here's how it all played out.

Owner had it towed to a friend of mine's shop, said he worked on quite a few 5.9s, so he could get it fixed up. However, after it sat there for over a month and hadn't been touched, the owner got, rightly, grouchy and sent a tow truck from Gaylord, MI, where he lives, down to pick up the truck and take it to a local shop that said they would get it in and see what the problem was. They did, and after pulling the head, they found not only was the head gasket leaking, it had scored four of the six cylinders, and the engine would have to come out for a complete overhaul costing $10K-$12K. Owner said even though he really liked the truck, there was no way he would put that much money in a '96.
So, he decided to sell it as is. I mentioned it to a friend of mine down here in the Elkhart area, said he was interested in it, so I gave him the owner's number, and he bought it for a grand.
The next Saturday, I rode with him to Gaylord, 270 miles north, in his '95 Dodge dually pulling a trailer to pick up the truck and bring it back to Indiana. After a six hour ride (my friend never got over 55mph) we got to the shop to pick up the truck. Lotsa fun there, it's raining, unpaved lot with about a half inch of slurry on top, had to drop the trailer so they could use a big forklift to pull the truck onto the trailer, did I mention it was raining? Got hooked back up to the trailer, put six 2" ratchet straps on it and loaded the ramps back up.
We were cold, drenched and hungry, so we decided to get some lunch, so we jumped in my Town Car which the owner had left at the shop for me to drive back, and went to BK for a bite to eat. Came back and headed back to Indiana, but about 10 miles down the road, my friend missed a turn and I had to flag him down and get turned around to go back to the turn-off. I followed him all the way back, (at 55mph max) until we split up to go our separate ways.
He gets it back to his place, unloads it the next day and parks it next to his shop. He intended to pull the motor and go through it when he got the time. About a month later, the farmer that leases some land from him saw setting it there and wants to buy it, so he sells it for $5K.
End of story.

I’ve done a few water pumps on my old 5.9’s and my current 6.7.... I’ve heard horror stories about aftermarket units so I’ve always bit the bullet and bought oem genuine Cummins water pumps. ($200)
And hopefully you buy them from the Cummins dealer not the Dodge dealer. Dodge just takes genuine Cummins parts, reboxes them and marks up the price. I buy all my 5.9 parts and filters directly from the Cummins shop. Thankfully I’ve mostly had to buy filters and fluids and not many parts.

Yeah, all the 5.9 and 6.7 Cummins used by Dodge / Ram are 3 gallons oil capacity
Wrong... the 96s take 11 quarts..... Probably same for 12 valve 97s and 98s. Check owners manual.

I replaced the water pump in Aug on my 96 12 valve automatic at 275,000. First water pump replacement since new.

Replaced the water pump twice in 200k miles on my 96. Both leaked at shaft seal at ~80K. Two bolts and <15 minutes. Simple O-ring seal. Hardest part releasing belt tension and retention. ~$50 from local Cummins shop.
