I'm 96% sure of my diagnosis but want to hash things out with experts.
Headgasket?
Hopefully not warped head from #3.
This is a 22R and I think another possibility that would allow these symptoms is worn through timing chain cover. Knowing history of this truck I very much doubt this but I didn't pull the valve cover to inspect. So not impossible but I never heard of rattling and he knew to look and listen for it.
The "something done wrong" is throwing me. Maybe coolant was poured into the oil and I would believe this due to brain fog. But the cooling system leak down and loss, I dunno what mistake could fit all the clues.
Happy to entertain thoughts.
Oil change and compression check? This seems self evident but since the truck is in Denver and I am not there's logistical complications.
I'm starting a list of things to do the HG under that assumption.
- Coolant loss.
- No evidence of coolant or oil under the truck or on the engine.
- Running hot (I hesitate to call it an overheat, it was running hot and he limped it home).
- Crankcase level very high (reads as though it's roughly one quart high) showing obvious oil and water separation on the dipstick. It's red fluid sitting on top of brown oil, it's more obvious than in my craptacular photos.
- Leaks down from 10 psi to 5 psi in a few minutes when pressurizing the cooling system.
- Vague hissing from back of engine, hard to isolate using a long socket extension to my ear. Hey, I'm no doctor with a handy stethoscope!
- Anecdotal mention of "Doing something wrong" by someone organized who did not make mistakes.
