Rear (right) timing chain tensioner failed as well as the cassette (or whatever the tensioner pushes against). Turned the engine over by hand and the timing chain (visible through the tensioner hole) appears to still move with the crank. Does this mean that the engine is still good and didn’t crush or bend the valves?
I could justify removing the engine and replacing the timing chain & cassette. But replacing the heads would be a death sentence.
