Was looking over my engine today while its waiting for parts to come in, its basically a short block atm, saw the rear cam bearing and it had some/a wear mark in it, not grooved or anything but, i heard and rode in the car this engine came out of and ran sounded fine, ill try to get a pic up when i get home, is this normal wear for an engine that has roughly 8k miles?

 

the darker spots are the wear marks, and there are 2 small scratchs u can barly feel in the 2nd pic





the front bearing looks the same minus the little tiny scratch, are these bad/should be replaced?

 

Here's mine with 10x that many miles, and the opinions....
Take a look

Those bearings are fine. Aluminum blocks move around more than cast iron blocks. Tend to see odd cam bearing wear, Completely normal. What would be much more important is the bearing clearances, you need special tools to check them.

 

Perfectly fine. I've never seen an LS motor that didn't have cam bearings looking all old and worn out. Even stock very low milage cars.

 

Ok thanks guys! Ive never seen them so wasnt sure lol, first LS build so didnt want it to go out of cause of the cam bearings lol

 

Mine looked the same.
