There is always a first time. I have no other explaination for the chain to break. Either the chain just failed, or the rail broke causing the chain to fail. It may have slipped a couple of teeth until there was valve interference, causing the chain to break. The chain ends look as if it was pullled apart. The engine was not under a great deal of load, it was not accelerating but at highway speed. It was not the valve train or the tensioner, they were OK.

I did forget about the double row chain. I thought I had read posts here that seemed to indicate that the double row chain was no more reliable that the single. I would have thought that the double row is probably over-engineered. To me that would indicate that it is not the chain itself usually causing the failure but another source. i.e. tensioner, sprocket wear, rails, guides...

Thanks for setting me straight.
