Complete rebuild.

Complete rebuild.

that's about the only safe way. good news is that a set of main and rod bearings from a reputable manufacturer (i got mine from napa) should only set you back about $150-$200 depending on what you get. i did my last rebuild for under $500 by doing all the labor myself.

I used to have a pretty nice Chevy Lumina that now sits in the junkyard due to oil level negligence......

The knocking will go away when you replace the destroyed bearings......

As long as he didn't spin a bearing causing damage to the crank and/or main housing bores...

I don't think he spun a bearing. That usually means theres metal shrapnel everywhere. Idipped the oil stick a few times while it was running and there wasnt anything on the dipstick. It was still pretty clean. Anyways, today were going to take the bottom end apart.

Does it matter if I mic. everything out? Or should we just go get the standard size bearings.

Are main bearings hard to replace. I did rod, not main though. Anyone have any suggestions for it? Do you have to lower the crank?

Also, Tim, if you see this. My dad said your car left a decent size oil puddle in a few spots in my driveway. You do have an oil leak somewheres. We will find it today.
