300 Tdi. Ran fine all day- normal EGT, normal oil pressure, normal oil temp, normal coolant temp. Parked it after a 45 min drive. Smoke from under the hood. Blew the rear most core plug- on the left side of the block. Completely out. No damage to it, looked like it just fell out. It was replaced about 4 years ago with the engine install/re-build.
Truck is parked outside and hasn't been driven in 6 days, but the front core plug heater was plugged in all the whole time so I can't imagine it froze at any point. And it was in the high 40's today.
Thoughts on what could cause this?
Thanks,
Alex
