Metal in oil pickup...HELP (Thrust pics added)
Hey guys, I've got about 500 miles on my 6.0 rebuild, pulled the pan and found a bunch of little pieces of copper and what looks like steel wool on the oil pickup screen. Everything was new in the rebuild...all forged internals, all high-end stuff, ARP everywhere, etc. Engine runs great, no knocks or noises... What could this be? Cam bearing? It is a twin-turbo motor..but I don't think turbos have any copper in them..

Oil pressure was low. I called the machine shop and they told me they left the mains a little loose due to my high hp goals, but who knows if thats true. I ran brad penn 20-50 for the first 500 miles. Why, will a bad cam bearing affect oil pressure?

Yeah I thought it sounded like a BS excuse. They did the machining, cam bearings and installed the crank. I did the rest. I'll pull the cam and see what the bearings look like.

looks to me like machining junk leftover that wasn't properly cleaned out from the oil passages, etc.
if all the passages aren't opened and cleaned fully, there are lots of places for crap to accumulate.
good luck with the engine. hopefully the bottom end is OK.

Valve seals are all new, but I'll check. I hate to pull the rods & crank, but I guess I may have to. Could a crank/thrust bearing be bad even though it spins freely and makes no noises?

Trans actually had a low line pressure issue. Could never get enough pressure to lock the converter. So thats getting rebuilt too. I just need to figure out whether to blame the machine shop or not. I did have low oil pressure and checked all the usual stuff. All galley plugs in, oil pump ring was in correctly, etc..
