Are these lifters done?
Are these lifters done? I was cleaning the head gaskets off today and decided to pull the lifters and trays out just in case, and I found this on the 8 passenger ones. Drivers side looked fine. Cam has matching stuff on it on those lobes.
I'm pretty sure both the lifters and the cam need to be replaced.

Any number of problems. Too many to try and pin down really. Normally they consist of the normal oiling issues, then maybe contaminants in the oil, not changing it properly/on schedule. Foreign debris. The list goes on for a while.
Arc00TA,
This can happen from getting on it too soon after start up. The passenger side is the last part of the engine to get oil & it get's there slowly on pre-04 LS1 blocks due to the narrow rear oil passage. It takes a couple of minutes for oil to get to the passenger side valvetrain. Always, wait a few before getting on it or just wait 'till she reaches normal operating temps. before moving the car.
You can watch for yourself, if you want to see it. Rig the coils up so that the car can be run without the valves cover on & watch how the oiling occurs. It will be a little messy & may get oil on headers, but, worth a look.

I know the oiling path from looking at the diagram of it, thats why I was suspecting oiling. Makes sense what you're saying. I never get on it until the engine is up to full temp. I've only owned this car for a few months though, so I can't say about the previous owner.
I guess this give me an excuse to put in LS7 lifters and a FI cam, since I pulled all this apart in preparation for my front mount turbo.
