The rebuild has begun!
Tear down:
A peek at the cylinder with the rocker failure:
No impact from the valve!
Though that bubble in the cylinder wall casting is unexpected. But I think if it were an issue, it would have caused a problem by now.
And the new heads are on!
Tear down to rebuild in one working day. ZB's the man. Can't wait to get this back on the road. I just hope the salt holds off long enough to burn off the tank of E85 before I put it in storage.
