this is my lsvtec from last year. eventually, it lost 40 psi in cyl #1 due to a scratch in the cylinder wall. it blew most of the oil out of the motor through the catchcan, so i probably drove around with half the oil in the motor for about 5-10 miles just putting around 2000 rpm.

i found this upon teardown.

just a few pieces. is this where it came from, the backing material to the bearings?



it wasnt knocking, the crank/friction side of the bearings didnt have any excessive wear, and all bearings were still properly aligned in the rod ends with the tangs. none of the rod big ends were scored/burnt/rainbowed

just want to get some clarity on this before i reassemble it once its back from the machine shop
