Tearing down the 110 for a GMR 113 build and although I will have all new parts, I noticed this. It is only on the one lifter and lobe of the cams that being the rear exhaust. All other rollers and lobes look as they should. 10,000 miles as of now.

What say you?

 

That lifter probably would've crapped out in another few thousand miles. Good thing you're doing a build. Getting some premium lifters I'd assume.

 

My thoughts as well. GMR lifters will be going in. So much for the newest SE lifters.
