bearing sitting in oil pan

[bdffej]

has anyone had their bearing of the lower counter shaft pop out of the bearing shell, thats in the block?
i was drivin along and the engine was at about 4grand and i was about to shift and i heard a pop and the engine dyed.
my dad tore the engine apart yesterday and found the timing belt stipped and the bearing from the lower counter balance shift sitting in the oil pan. nothin else seeems to be wrong with it.

Sounds like a bearing seized, took out the balance shaft belt and then skipped the timing belt. If that is true, you probably have a lot more wrong than just the bearing. These are interference engines and don't take kindly to skipping timing belts.

He's right, DSMs and timing "issues" don't get along kindly. you may want to tear down further and investigate your valvetrain, pistons, cylinder walls, etc.

I had a balance shaft drop into the oil pan. Mine went out clean and left the shaft flopping around and cutting into the block. We pulled and rebuilt with very good success. -Ian

If the timing belt stripped, you are in for a cylinder head replacement. The balance shaft bearings are actually 2 piece bearings, although you can't see the parting line. The bearing did sieze, and it was spun out of the bore. You probably have a ton of engine damage so you might as well pull the motor and do a complete rebuild, and I would find another block, as you can't bore the balance shaft bores for bigger bearings. Even if you went with the balance shaft eliminator kit which basically means removing the balance shaft bearings and spinning them so the oil holes do NOT line up, and leaving the balance shaft bearings out, I wouldn't trust that bearing to stay in place in that bore. If it came out again, it would total your new motor due to low oil pressure. Only option there is to plug the oil hole with a set screw, which is hard as hell to do....or weld the hole shut. Prepare to empty the bank account or find another motor though, as your cylinder head certainly is toast from the valves hitting the pistons.
