Okay. This may be lengthy... I bought a 1989 International S1700 full size bus with the 7.3l non-powerstroke diesel. I drove the bus from the previous owners house (he was the school districts' bus mechanic, he started the thing with a small squirt of starter fluid after plugs warmed up), the drive was about 10 miles and then I parked it on property. I pulled the seats and stuff, beginning to turn it into the dream RV. I removed the lower radiator hose when a freeze was threatening and refilled the coolant system with 100% anti-freeze so there was no question as to the temperature the coolant was able to stand.
This is the state in which the bus has sat now for about four years
So, I am now trying to resurrect the beast!! Started with a hot battery. Had trouble with the "brake pressure" alarm on the dash, I will not shut off and quit buzzing... I believe this alarm is preventing power from being sent to the starter as turning the key does nothing. Then, we took a jump wire to the starter solenoid and BANG, the start engages but cannot turn the motor. Then the starter was removed and rebuilt to good-as-new (just to eliminate that as a culprit). Put the starter back in... Did the jump wire again with the same result as before.
Now, we removed the mountain of rat and field mice poop and nest material on top of the motor. The buggers chewed up a two of the glow plug wires but that appears to be all (thank god). Then we soaked the holly piss out of the glow plugs, removed them (this involved a lot of patients and BP blaster)... I used a small straw to stick down each plugs' hole and see if there was any fluid causing a "hydro-lock" situation, NOPE! Then I sprayed all the BP I had (about 1.3 cans) into all of the cylinder heads. We allowed this to soak overnight, plugged in the block heater and waited about 2 hours, got a 15/16" deep well on the cranks' bolt and wrenched with a breaker bar... I went in both directions, when counter clock-wise I would end up loosening the damn bolt, the motor would not turn at all in either direction with the glow pugs out and soaked overnight and the blocked warmed and all the belts loosened..
Now, I am looking for any help at all as to what else I can do?! I fear the motor is shot, rings seized to the cylinder wall somehow . How could that be the case though when the bus was running perfectly fine when parked and not allowed to freeze?
Any and all help would be greatly appreciated, I read forums all the time to help with my cars, trucks and now buses. Thanks ahead of time for this one
I have included some pics. There is one of all the glow plugs, one of the worst glow plug, and then on of a broken piece just at the end of the throttle cable??
