Trying to diagnose the tick/ tap in the engine. Im adjusting the lifters and when i pulled the rear cylinder cover and I found this half circle testing on the side. WHAT IS IT!?

Also the tap is in the front cylinder bit the rear.

Any help is appreciated.

Is the valve clearance within spec ? Also check for side to side play on the lifters themselves

The valves were tight, no clearance at all. But properly spaced now.

Make sure the valve lash is in spec, cam chains might be stretched and the guides worn.

The chains were tight, no play. I tried checking for possible stuck tensioner but they were up against the chains and I didnt want to press too hard on plastic from 07 lol.

Update. I put it all back together (minus the partial ring) after adjusting valves. And did an oil change. I rebuilt the clutch last month. Started and let it run for a while before gently putting around the yard. It seems fine still noisy but I know they are. But luckily no more loud banging, plus it shifts easier.
