Red, after resurfacing your flywheel, bolt up the clutch and have the whole assembly balanced.

I actually managed to find another flywheel so I will probably throw the old one in the scr*p pile, and get the one I found resurfaced. Red

Your flywheel has a "checked" surface, likely from a slipping clutch. Usually they can be resurfaced if the flywheel itself is not cracked. If the cut is drastic, the portion holding the pressure plate bolts must also be cut a similar amount to preserve the ability of the clutch disc to be properly gripped. We have resurfaced many that look that bad. The broken chunk seems to be from the top of one side of a valve guide.

In the first photo, the left intake runner (#1 cylinder) is "normal", while the right one (#2 cylinder) the piece that is higher is part of the valve guide. The second picture is the piece that was in the #5 valve port, but didn't come from that valve. I hope to get more photos after I get the engine rebuilt. Red

It is hard to tell what that piece is. In the first photo, it looks like a piece of the block is missing in the left hand intake port, but that piece doesn't look like it is the piece.

One more of the flywheel. A little machining will take care of this right?

I can't make this stuff up. This piece was in the number 5 intake runner. I thought it was a piece of the valve guide, but I ended up taking the valve guide out and it was complete. I really have no idea how it got there.

That would help, Red. The probable reason for valve guide failure would be loss of the fork that holds the guide in place. Carbon buildup in the valve stem might do it, if it caused the valve to seize in the guide. My problem is understanding why it would involve two valves at the same time. The old style two piece guides almost never break, but a broken or weak valve spring could allow the fork to fail by releasing tension on the assembly. We check for valve problems with dry/wet test. Compression is checked dry, then oil is squirted into he cylinder, and a new test is run. If the compression stays the same, or close to it, the valves are leaky. We will be interested in what you find, such as a missing fork lying in the bottom of the valve chamber.
