Rocker adjuster
Well... I'll say it's new, I took motor apart to fix rear main seal, pulled the seal cap and no side seals were in it, checked bearings, they were bad, pulled motor apart and had .0055 main clearance and .001 on the rods, pistons were .002 tighter than reccomended. pin end of the rods were tight and big end was out of round. Well never use that shop ever again for anything. Took it to another shop and had all machine work fixed.
Putting it back together I switched from a solid ft to a solid roller, new rockers.
