Mack superdog Posted March 27, 2023 Share Posted March 27, 2023 So I found this stuck to my drain plug when I changed oil on my e9 does anyone have an idea what it is it looks like a bushing of some sort but not a main or rod I thought maybe it was from the air compressor so I took an old one apart and nothing in it that’s similar so I’m thinking either wrist pin bushing or maybe the turbo bushing any help is appreciated pictures added below Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/ Share on other sites More sharing options...

Specially If you got the engine turned up !The shape is very similar to wrist pin! to big for turbo peices ! compressors is ball bearing! Just sayin!

mechohaulic Posted March 27, 2023 Share Posted March 27, 2023 expanded picture large as possible , tough call. based on smooth sides a liner piece would be in top five possibilities. any other contaminates in oil. this is a situation why i always use a clean drain pan when oil changing. let old oil set a while then run a magnet through see what fine particles show up. oil analysis might help. how was engine running ?? noise/pressure etc 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528014 Share on other sites More sharing options...

mechohaulic Posted March 27, 2023 Share Posted March 27, 2023 could be one of those things which will never amount to anything; but has more of a mental strain on you ;;, always wondering driving down the road. if not being done at present time , possibly oil sampling if there is availability . helps monitor internals. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528025 Share on other sites More sharing options...
fjh Posted March 27, 2023 Share Posted March 27, 2023 Wrist pin bushings come out in chunks like that rarely any fuzz keep a close ear on that! If you find more next oil change pull the pan and start looking just sayin! Hopefully it makes it to the change with out a failure! 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528027 Share on other sites More sharing options...
Mark T Posted March 27, 2023 Share Posted March 27, 2023 Probably better to pull the pan off and give it a thorough look at the wrist pins. You might find yourself looking in there without removing the pan. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528033 Share on other sites More sharing options...

You might find yourself looking in there without removing the pan. It is really hard to find the offending rod until the chunks are bigger ! Usually happens on the bottom of the bushing though! you need to bring each piston to the bottom and look real close! 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528037 Share on other sites More sharing options...
Mark T Posted March 28, 2023 Share Posted March 28, 2023 It is hard to see, but if the bushing is walking out of the rod, it's not impossible . It'll be hard to see it if it flies apart too, but that'll be from vision distorted by tears 😪 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72645-e9/#findComment-528040 Share on other sites More sharing options...
JoeH Posted March 28, 2023 Share Posted March 28, 2023 My first though was compression ring, but that'd have a hard time getting out and dropping down. Looks like it's a bimetal piece, 2 separate colored metals appear to make up the piece.

AZB755V8 Posted April 2, 2023 Share Posted April 2, 2023 (edited) That certainly looks like it is Bi-metal with a large radius. It maybe a piece off a well worn crankshaft thrust bearing. The rear side bearing does wear especially with a stiff clutch and being held down for extended periods of time. This could be the outer lip that is generated as the crank wears into the bearing. Crank walk and adjusting the clutch would be a sign of this.
