More news from the engine builder. He has the engine torn down and the good news is nothing is damaged at all except the cam has broken right behind the flange that bolts to the cam gear. We both say it is a bad casting and would have broken sooner that later. The loose flywheel bolts are another thing. I have to look through my receipts but I supplied the new bolts and flywheel to the builder because the engine didn't come with them. I bought the bolts from the type 4 store or LN engineering either way the bolts are soft and not good. Bill said the had stretched. He has ordered German stock bolts. He also found that all 4 heads were leaking at the bottoms. He is going to investigate why the had leaked but told me regardless of the reason he wants to use copper rings that are machined to fit into a channel cut into the heads. He does this for turbo 911 engines that develop huge cylinder pressures. He has guaranteed they won't leak when he is finished. Just think, the engine ran strong with leaking heads, I am excited to think how strong it will be now with the leaks fixed and the stronger cam. Bill has all the parts ordered and will be working on the engine later next week.
This engine was going to have issues one way or another. The flywheel was on the edge and the leaking heads had to be addressed and the cam was probably defective. All part of the fun, really, no kidding!
