Well !@#$. I'm sorry Sean, that's not fair at all. When someone goes through the trouble to take all the precautionary steps and this still happens? I'd be out of my head. Only thing left to do is to break things down and start over. Take a day off first and grab a beer with some friends, that's what I did when I had to rebuild everything again.

No. I pulled the pan, 1 and 4 rod caps, and the girdle last night. And then was just over it. Went home.

Plan on doing that this weekend with ER in town. Lucas is gonna look at it, but if he gives it a terminal diagnosis, it's going to be set aside for a few weeks at least while I finish up some client cars.

It's so odd. Just about everything was new, so where could the contamination come from?

I'm pretty confident in saying you don't have copper in your oil, but check the rest of the bearings. It's very obivous once you've worn thru all the babbitt layers on a bearing.

if you and Lucas don'r find anything conclusive I would send an oil sample to Blackstone or another testing lab as see what the metal content is.

What was the background of the block? You used a 64 block yea? Was it a junkyard motor? Was it shot peened or glass beaded?

4g64 block from junkyard on EBay. Still had oil and water pump on it what I got it lol. It was thoroughly hot tanked by the machine shop and cleaned by me prior to assembly.

I'm really sorry this happened. I get a pit in my stomach just reading about it. I know your gonna get it sorted and it will just be a little setback. Just to toss it out there, did you replace the oil cooler? I've been told those things hold all kinds of crap after an engine failure and are pretty difficult to get clean. Anyway Gluck looking forward to reading about your findings and recourse.

Is it just your main bearings worn? How are your rod bearings?

Hot tanks don't get everything. Hell even sonic cleaners don't get everything. Did you pull all galley plugs and run brushes through them?

Two things I would like to know more about that come to my mind after searching through this thread.

What crankshaft did you use? If you used an OEM crank any pre-processing done to it before installation into the block?

Did you check the thrust clearance of the crank to the block before you removed it?

All plugs were pulled and the various ports cleaned with bottle brushes. I do this on any engine.

94mm Eagle forged. Thrust was good when assembled, thrust is still good. Measured identical to what it was during assembly.
