Who wants to see a ventilated 4.0?

Brother in laws 94 wrangler tossed a rod with 106k on the clock.  Currently swapping in a new used motor from another 94 with the same mileage.

man, breaking a 4.0 is not an easy task    I've seen some pretty nasty 4.0's run.

Yikes!

 

Any idea why the rod wanted to go on vacation?

No idea, kid was just about to accelerate onto the freeway when it knocked and stalled.  He started it back up and it obviously sounded like crap.  It was his Dads jeep for years and he flogged it pretty hard, guess the boy just got be the unlucky one when it let go.  I'll pull the pan and look inside when the motor comes out this weekend.  It's almost ready to pull but ran out of time.

Got the motors swapped this weekend, new used motor seems to be working fine.  I did get a better look at the fragged motor and noticed the rod also snapped the camshaft.  If you unplug the injector and pull the rod you'd have a good running 5 cylinder motor.
