aren't some 50DN use gear drive?

Not on series 60 engines ,the only place you find that piece of crap is on the 2 stroke engines in buses

Thanks for the ideas. I will keep this forum in the loop on what is found. I misspoke about pulling the head. I should have said pulling the valve cover. It’s quite a chore on the Newells because the bathroom floor access hatch has to come up to get the valve cover off.

Richard the turbo and the air compressor returns to the oil pan  also

I just can't imagine what else in the engine could melt copper and drop it in oil but still have the engine run normally. Thrust bearing maybe? If that was really tight at initial startup I suppose it could melt down the thrust flanges. Might check the crank for end play.

I think it is the ceramic cam rollers

probably read wrong(me)--your 99 should be a pre egr engine. My 2000 60 series is pre egr.  There was a problem with lifter and head bolts around then. They said to replace head bolts one they were used..Cliford is much  better than I on this stuff.. I am still curious..Bob

 Bob the series 60 used powered steel at some locations in the head like valve guides it is supposed to be stronger than other material but I never did buy into it myself

Cam followers and all bearings look good. No brass or copper glitter in the upper end.

The 50DN alternator appears to have been changed out sometime in the past.

The leading idea by the mechanics and gray beards in the shop is the alternator fried and deposited copper in the oil pan.

But all of this is conjecture.

Thanks for your input.

That is a hard one to figure out since copper melts at 1984 degrees and oil has a autoignition at 600 to 800 degrees

Have any of you ever seen anything like this? This was found in the oil pan of a Series 60 engine powering a Newell.

Did you find out what it was ?
