So I finally broke in my engine, ran it for 20 minutes and now I'm doing the first oil change. I found almost no metal in the oil from the pan, and the normal super fine metal filings in the oil in the filter. What has me concerned is I pulled the pan and found some metal flakes at the bottom of the pan. They're silver in color and non magnetic.... do I have a bearing problem? Should I pull the main caps?

This is after cam break-in?

If it's all new stuff and those are non-magnetic then I would guses they have to be from the pistons? But, if all else is well, like it has good oil pressure and such. Follow on with oil and filter change and go with it.

Did anything get painted silver?

I would not be real concerned, probably some left over gunk or self clearancing going on :) Just keep an eye on it. I make a habit to cut open the filters spring and fall myself to keep tabs on whats going on.

The entire engine has been overhauled. Got it as a 350, now It's a fresh built 383 stroker motor with a roller cam. Everything is new inside. The engine had good oil pressure the entire time it ran.

Just keep checking it. Don't be afraid to pull the motor and check all the bearings. At least you have a SBC. On SBB the front cam bearing being starved, nicked, or anything can ruin the whole motor. Especially worrysome because of the front distributor.

I've seen your threads about your SBB, that really sucks.

The engine is on the stand with the pan off as I ran it on a home made engine crate. I guess it couldn't hurt to pull a couple main bearings just to be sure.

If it is on a stand with the pan off I wouldn't hesitate for second to pull things apart to verify everything is ok.

Unless it's a roller cam, I wouldn't worry about it. All new cams though, this is the reason you change the oil after the first few hundred miles.

^that would be true if it was magnetic. sorry all. I admit I was quick to answer this one. BBC has it right, pull the sucker apart.

You will have that with the normal break-in process. Ok I read the first post again a couple of times :doh: yes if there is more than the fine metal I would definitely look into it just to make sure there's no issues.

I just pulled the #2 main cap, this is what the bearing looks like

I don't see any scoring on the crank journal, but I can feel some of the scratches and some crap embedded when I run my finger across the bearing. I think it's ****ed :( I'll double check with a coworker who's rebuilt many motors.
