Engine break in 1st stage oil results

[Jake Raby]

The wear metals seem really high to me, but pics are only so effective when judging these things.
I hope its ok!

removed the sump this morning.
First impression was it looked clean. There are a few small bits of sealant goop but appeared to be nothing else.
Just to make sure, I took the magnetic drain plug and dragged it over the entire surface of the pan and the macro pic of the drain plug is the result.
Considering this is the 1st stage oil change in a rebuilt I would have thought there should be some bits?
When I looked up into the engine cavity it look clean. Pick up strainer had a small piece of sealant goop but that was it.

Sump looks better than I expected. The material on the magnet is concerning, just because of the size and shape.

Thanks for your help Jake.
Just want to point out the magnetic plug pics are macro so the camera lens is only about 2-3 inches away from the plug.
Also the bearing that turned, was on the main crank shaft, it was the end bearing in the bearing case just before the crank pulley (opposite end to flywheel). I hope this is a clear enough discription.

Jake I just thought, do you use a magnetic drain plug in all your rebuilds at this early stage?

Out of curiosity, last night I put a string around the magnetic plug and lowered it into my oil sample, wondering if there may be suspended metals in the sample. After 30 min. when I pulled out the magnetic plug it was clean. So those extra fine paste like fillings on my drain plug in earlier pic are not small enough to be in suspension.

Absolutely, the mag drain plug development was a result of the demand of my engine program. I will post a 500 mile/ 50 dyno run mag drain plug pic from a Raby engine later.

The assembly lube was a red assembly lube and since new ARP bolts went in the ARP lubricant was used, a black lubricant.
At this stage the rebuilders were not to concerned with the results so as soon as I get my new magnetic drain plug I'll put another 500 - 600 miles on the new oil and then do another oil change.
