Thread: Valve train wear or normal wear? Expert advice needed

Looks really good to me. That wear is nothing to be worried about. Just polishing from the break in looks like.

The shim looks weird from this angle. Just do what the others said and make sure it isn't chipped, cracked, or broken.

normal. you said they been there for 2 year right? second on the oil squirters. did you take them out and blow compress air in them? i did that to DC scottys squirters and all but 3 were cloged on both raiis. took alot of break clean and air to open them up

cams look fine. the edge of the lobe will have a lip if its worn or pitting. it doesnt appear that your cams have any of this.

the lope smooths out over time due to the ecu adjusting to the s4's.
