Dang.

Are you using a 3/8" ratchet? If so, try using a 1/2" breaking bar. You'll get better leverage.

Yeah, using 3/8s. I had no other socket that would fit the breaker I had. Even then, I used a long-handled ratchet AND a length of pipe, and still no budge.

I am seriously wracking my brain trying to figure this out. I know rod bearing won't do this, was thinking maybe the oil pump, or something in the timing chain and gears. Or could be the balance shaft? Note that no matter which direction I tried, it would not move at all!!

Have you dropped the pan yet? That'* what I would do next. Carefully inspect the oil for metal shavings. Then, take a peak at the bearings/journals.

If it was the balance shaft you should get a little movement via the timming which should have a bit of strech... You should have had a little bit of movement.. I think its a rod bearing... You'd be amazed at how they can move out of place when they spin..

Should be easy enough to drop the oil pan and check...

Still sorry to see it happn tho..

No bang, no thud... It just stoped and that was it...

Once I saw the oil pump gears in the timming cover actually split in half.. Strangest thing I eve saw on a 3800... You could pull the cover and have a look.. A bit of a PITA...

Let us know if you find out anything else..

Well, we can rule out hydro lock.

After owning a Series II N/A, that'* the FIRST thing I checked for after the battery came back good. Besides, having the plugs out makes it alot easier to turn the motor by hand or by weak starter.

Maybe I should start a poll on who all thinks is making this motor bind up. Hopefully I will find out something later today or tomorrow.

****I wonder....could a rod bearing actually spin itself 90 degrees on the downstroke and by force of the other pistons be driven up the cylinder causing it to lock the motor?*****

I'm not so sure. If a rod hydrauliced, it may be bent enough to stop rotation.

Sudden stop without related nasty noises from rod bearings is almost always hydraulic lock, in my opinion.

Did you check the cylinders for water, and the coolant bottle and radiator for coolant? How'* the oil look?

This doan sound too pretty good, I'm sorry to say.

Y'know, I made a comment in another post that I was getting a very wretched knocking noise. I ORIGINALLY thought it WAS the rod bearings, but was also leaning towards the harmonic balancer since it was wobbling around. I ordered the balancer, but cancelled it when the motor locked, as it will not do any good on a motor that ain't running. Just for craps and laughs, here is the video clip of it running...there isn't any picture but you won't need it....

Listened to the clip.

that'* not a balancer, it'* a rod bearing. Your sudden stop is due to a rod bearing turning.

Sorry.
