used 6 bolt block, oil pump seized, what to check for?

Going to pick up a used 6 bolt block with stock rotating assembly. He said oil pump seized, what else should i check? Cylinder walls are good.

Check the bearings. Crank, rod and balance shaft should all be checked.

Check to see if it has an ebay BS delete kit. More than likely the cause of a seizure today. Look for hot spots on the crank and block. Look in the cylinders to see how bad the scarring is. Check to see if it has been decked before. If it has already been decked I would just forget about it. If you need to deck it again it might be too low.

okay thanks guys, I appreciate it. what's a good way to check the bearings?

 

[kthackst]

If the rod jiggles side to side thats bad, or any direction really.
Take the cap off and check for scoring and wear.

You should probably take it to a machine shop to be checked over. Have it completely checked before you waste a ton of time on a worn out block.

balance shafts are still in and it has never been decked

When i got my block i just tore it down and rebult it, and had the block decked. Crank polished, new bearings, thats about it, oh yeah bse.

I think ill do that, just rip everything out anyway and get new bearings etc...
did you just use the stock rods/pistons? or go new?

For my goals i keep it stock except for the bearings, ill upgrade later but for now its enough.
