A bad vert, no way. You would still be able to get some kind of crank movement.

A spun rod bearing, crank can still move there too, clearances.

A spun Main,Yep, Locked up Tight.

So , there is my Out on the limb, Big Fat limb opinion. work

Good news though, is there wont be a lot of carnage. up

he drained the oil & said it looked OK, he cut open the filter & said there was some "fine" metallic particles, nothing disturbing.


Could be bearings but I would expect more shrapnel in the filter.

I have seen a front pump seized up solid. Thought it was the crank until they tried to separate the engine from the trans. Took a 6 foot bar to get it apart.

If the trans is good my bet is still pistons.

When mine jammed the converter bolt, the motor would not budge in either direction with a breaker bar and a pipe. Didn't really hurt anything except the bolt and the threads in that hole in the converter. Still has same flex plate, converter, no block damage,only very slight scratch.
