Engine builders and super mechanics - help identify this part please!

While changing the oil in prep for an upcoming event at Laguna Seca, this turd came out of the drain port. I'll know in a day or two its exact chemical make up, but some early speculation from you experts would be welcome.
Need any background info? Track car, not always treated nicely, Carrilo A-beams, JE Pistons, SUBs, double-springs, etc. Thanks! |
need better pics
|
Looks like a shim which goes between the crank and the rod. 2 on every rod.
I just removed my stock rods yesterday. Telltale sign is the little bent clip edge on both ends which locks it in. Pray to the gods this fell into the sump and its one of the stock originals and not your new built engine. I would be talking to the engine builder.... And getting them to check it. However the fact its bent..... :eek3: Did you blow the stock rods? May have fallen in and sat there under the sump pickup shield. |
looks like a bearing but you'd know long before an oil change if your bearing went out.
|
I disagree, its too thin, and any bearing that has been fuked in the ass like that will show its copper colored layer, etc. Its also the wrong shape, although that could have changed during its exit.
Looks like a shim or the metal part of a seal or something. Maybe a piece of the windage tray. |
looks like the shims that go under the valve springs to me. not sure how that would have broken but thats what it looks like.

Not sure what you are referring to?? |
Good info so far, thank you.
Engine runs, sounds, idles, and pulls very well. . . at least for now. It's not a fresh build, but I'm not immune to a money shift here or there either, which is what I'm worried about. |
Those aren't bearings unless your engine has been miniaturized. Some sort of shim.
|
Thrust washer?
|
Sure?
|
Edit: actually on second look, is it half moon flat shape?
I have 2 of those on either side of the cylinder 3 crank weight. Maybe just a balancer? https://cimg6.ibsrv.net/gimg/www.mia...074c297fe2.jpg |
My first thought was thrust washer.

way way way too small for a thrust washer. see my pic below for the stock shim that goes under the stock valve springs. Not sure what was used on your double valve springs but this is the only thing in your engine that i could think it to be. I just assembled a 2003 VVT engine so it is fresh in my memory.

My guess is an oil squirter crush washer some how broke. Heat maybe? although it doesn't look copper.. |

*Almost* looks like its been worn down too much to be a thrust washer. Also looks like its to small of a circumference to be a thrust washer.
