Ok guys, we the car to the Mustang Steve Bash in Clinton Michigan and made it up with no issues. We are now in Detroit!! Had just shifted back into 5th gear around 50. The car started to shake, I thought a tire came apart. I pushed in the clutch and headed for the side of the road. On the way to the shoulder the engine died. Did a walk around on the side of the road, all tires are good. Under the hood, all looks as it should. Try to start the car, it does not want to turn over.
After a wrecker ride to the nearest hotel, I start looking for the cause.
No water in the oil.
No loss of coolant in radiator.
Pull valve covers, push rods look like they are supposed to, nothing appears bent or out of place.
Pulled the spark plugs, they appear ok to me.
1-4 right to left
5-8 top to bottom
Use the ignition to spin the motor over. It goes about a turn and a half then stops. Hit the key again, and it spins even less and stops. Popped the distributor cap to look at rotor, it turns as the motor turns.
Loosened all belts, the water pump and all accessories spin freely. No improvement to length of time engine will spin over.
I used a long ratchet on the harmonic balancer bolt, it was all I could do to get it to rotate a small amount.
Took a picture through the hole in Scatter shield of clutch and TO bearing. It looks like it should.
I don’t have an oil pressure gauge, it hadn’t made it high enough on my priority list.
I have looked at all I can think of and went about as far as I can without draining the oil, have I missed anything? Thoughts?
I have a bad feeling about a spun bearing or something worse.
