added info:

Hi all help appreciated.

Today i removed my valve covers to replace leaking gaskets.

when i removed my Driver's side valve cover i found a piece of what looks like a clip that was wedged inside the rear oil gallery on my 351 cleveland.

Can somebody tell me what its from?

my engine was rebuilt a few years ago and this was not there the last time i opened up the valve covers.

i can not find anything that looks out of place in my lifters or rockers. the clip has very little damage to it. it appears to have cracked off from where ever its home was and then Wedged inside the oil gallery to the rear of the engine.

I have no idea when this piece fell off or what it goes to. engine was running well all last week, vacuum was good.

the broken part also appears to have part of a Fomoco Logo right where it snapped.

please help.

Wanted to add i just tested the piece and it is magnetic.
well i figured out what its from:

teflon valve stem seal.

I thought it looked like a valve stem.....good news....maybe you only have to pull the head on that side.

I think this is not so bad. You dont must be pull your heads. You can fix it with a air pressure tool for the sparkplug hole and a spring compressor. Bring the cylinder to the upper death point when the valves are closed. Then put compressed air in the cylinder to hold the valves closed. Now you can remove the springs and the valve seals. You can build your own fitting with an old spark plug. Summit have the compressor for the springs.
You dont need the gun, Its not so bad at all :-)

That process works, I did it a long time ago on another car.

well at this point i have none of the tools nor the skills to accomplish this, i have a competition cam rocker setup, so i don't know what complications will occur.

my fear besides at worst pulling the heads, is where is the rest of the valve stem seal.

Don't laugh, but years ago I read an article that suggested running the piston to the bottom of its stroke, then with the spark plug removed--pushing in about 20 feet of soft rope (like clothesline) leaving the end hanging out. Then turn the engine over by hand to get that piston up to the top of its stroke. The piston compresses the rope against the valves holding them in place while work is done to change seals/springs/etc. This is how I did my first valve seal swap on the first 351C that I had. It worked great and did not require any special tools (other than the valve spring compressor).
