I have no clue how it got like this. It was driven last year per the seller and the engine was covered.
I have the drive shaft removed and the brakes caged ready to be towed to my place. Iíll pull the heads off and see how bad it is.
Nice bus otherwise. 71k miles and new tires.
Glad to hear it has new tires and that nice drivers seat...
For that kinda water to seize the mill:
1) Coolant in the engine from blown head gasket or cracked head, or cracked block...
2) engine sat with the carb removed while the rain poured in...
(that happens way more than it should -- tears...)
I would suspect the previous owners memory is faulty or worse...
But that doesn't matter now --you own a bus!
Even before the work of pulling the heads I would pull the oil pan.
If waters been sitting on the crank you're looking at a full rebuild/machining.
If that's the case I'd be looking at finding a new/used motor.
And seeing what it takes to swap in a more modern eng/tranny while you're at it... Unless you're into the idea of an ol' school chevy big block...
Ahhh, back in the day when Eldorado's came with a 501...
