A suggestion. Drain the oil through a paint filter, the paper cup type you can buy at any hardware store. That way the contaminants, bearing material, metals, etc. get collected in the filter. Then you can take that to the engine shop and put the ball back in their court.
 
Closing out on this thread. After a painful tear down and a complete inspection on this Engine we found that when it was rebuilt by a shop here in Florida the shop didn’t do a few basic steps:

-Didn’t Remove the end plates
-Didn’t Boil the block or flush ALL the oil Galleys
-Didn’t Clean the block of all dirt and old metal

After taking this block fully apart I found some really old 40+ year oil that still had lodged in the galleys, a few old washers caught in the oil passages in the end plates and more metal shavings than I cared to count. All of this wound up in the bearings, wasted them and created some minor scoring on the journals as well.

Lesson learned – no matter what recommendations you have, inspect the shop personally and look over them as they rebuild the engine. These short cuts could have been avoided if I just visited a few times while they were rebuilding this Engine and called them on it.

Next Steps: Totally Rebuilding and balancing the Short Block, with all new bearings, pistons, crank regrind and a rear seal kit from DWM. Hope to have this back in by Christmas :smile:
 
WOW Michael..

What a bummer....and you actually paid them for the work.....its no wonder we like to do things ourselves..instead of hiring "professionals"

Unfortunately, those weren't shortcuts. Negligence or incompetence are words I'd use. I've heard enough horror stories to be glad I did my engine myself. John Loftus has some stories too, but not so drastic as yours.
 
Problem is it is hard to find people who have pride in their work anymore. Thankfully I had my block done in 1986 by Bailey Bros in N. California, a well known speed shop, and the old guys there knew the 6 cyl motor well. They did a beautiful job on my block and 80K miles later, there's not a hint of burning oil or reduced compression. It really helps when you deal with people who know what they are doing.
 
Being in the automotive repair field, I would like to ask a couple of questions.

What did the machine shop say, when your brought to their attention the negligence on cleaning?

Or did you not approach them after you found the shavings?
Reason I ask is because if their labor caused you a monetary expenditure they are liable. You should be able to recover in a small claims court.

Something to consider.
 
I did inform them I had an issue and there was metal in the oil. They did offer to relook at the Engine, I declined as the head had to make two trips already for poorly reamed guides. They did state in writing they replaced all the bearings and cleaned the block correctly.

I'm going to take the report from the second shop and the old bearings (they tell the tale well) and offer them as proof that there was an issue and allow them to correct the issue with a partial refund.

Not overly hopeful but will give them the option to correct the problem.....
