So I changed my oil after 100 miles in my 331 and found very tiny particles colored silver, and copper/gold. I know the copper isn't good news... Your thoughts?

Thank you

Spun bearing.

My 347 had one go after 300 km's.

I had to buy a new crank, rod and bearing set. Put it back together and now have 2 years on it.

You may have caught yours before any further damage. Good luck

Have you cut open your oil filter to see what it has trapped? Sounds like the engine is eating itself (main bearings). I'd get in contact with your engine builder ASAP!

Could tell you if it's a bigger problem than just a bit of break-in wear.

Can't think of anything other than bearings that would be the source of the gold/copper colored stuff. I'd be placing a call to the engine builder (unless that's you) to get their opinion on next steps.

I haven't cut open the filter. So you guys think the motor definitely has to be torn down?

Most all the particles came out of filter oil

If you have copper in your oil the motor is at minimum wounded. Pull it out and check the rods and mains, if they look good look to the cam bearings.

I think you need to determine the severity, by pulling the pan (if capable) pulling a couple mains and rod caps and posting a pic. Otherwise, revisit whomever built this engine for a discussion.

Not what you, or anyone, would want to hear, but there's no easy way to sugarcoat news like this. Take the oil pan off and start removing main and/or rod bearing caps. You won't have to look for very long before you find the problem.

I think before you go nutz ripping your car apart, you need to flush and change the oil and drive another hundred miles and check it again. Having some metal in that first oil change is pretty normal.

I put 100 miles on my 408W and had the oil analyzed here at work- there was so much crap in it that I about shipped my pants! My co-worker said change the oil and filter and run it some more. After another 200 miles, all the bad mojo numbers started to drop. Another 500 miles and they dropped again. Currently I have somewhere around 2,500 miles on the car, the last oil sample had nothing to worry about, and it runs and sounds great. Now I'm not saying to just drive yours and forget about it, just that there's a possibility that it could be nothing to worry about like mine... Hope that's the case for you too!!
