Bought a 99 Dakota with a 3.9 v6. clean little truck, but it needs a motor.now my question is the guy said it locked up going down the road. no holes in the block, but you aint moving the crank--tried with a bar. So what would have done this?havent pulled it yet, may just sell like it is, dont have time.unless someone feels its a easy job and possible easy fix in the motor.So what do you think guys?

Spun bearings... due to lack of oil

PLugged pickup screen is common.
Pickup probably clogged with sludge and starved the oil pump. My parents bought a used 96 dak with the 3.9 and it did the same thing. My dad shut it down when the lifters bled down on the highway and started clacking away. Had to pull the pan, remove the pickup and clean everything out. Pulled the valve covers and they were full of sludge too.

Rod bearing. Easy fix, usually. R.
Other than having the crank turned
