if it were mine, the engine would be coming out.

After checking the oil filter I will be pulling it out.

Best guess: off timing sprocket

Rocker arm pieces ?

I checked all the rocker arms, all looked good.

Check lash also? Maybe a lifter...unless you don't run roller lifters..


I agree with the take it apart idea...good luck

Not a piece of a valve spring or retainer?
Guide boss?
I cant discern much from the pictures....

Valve spring material. Looks to be the dampener coil between the outer spring and the inner spring. Does it have dual springs with a dampener in them? If so i'd start looking at valve springs. Put a new set of springs on it check the rest, account for all missing pieces, install new springs roll on....

Oil pump

I pulled the engine out and got it on the stand. I will disassemble shortly and see whats going on. After cutting the filter open I found metal in it.

That was my thought as well.

what kind of metal in filter,that pic looks like spring dampener to me

I pulled apart and found a Small set screw went thru intake. And stuck in the piston and made some Mark's on the piston and head. Also found the end of a valve spring. Checked all bearings and oil pump all looks good. I'm gona take my heads to the machine shop and get them checked out. No metal in the pan or in the block.

So were did the set screw come from throttle blades?

No throttle blade screws are still in it. I'm gona look inside the carb .

Not trying to be an a$$ but how does a set screw from inside the carb get inside the motor? Passages aren’t that big.
