Well, what I found wasn't unexpected but that didn't make it any easier when I found it. But, I promised a more or less Step by Step, so here goes.
Pulling the fan. This has nothing to do with the cam chain issue but I'm going to an e-fan and I was curious about the condition of the fan. Turns out the fan was perfect.
The rear engine cover. Under here is where the problem lies.
Pulling the water pump. This to was in pristine condition.
The nice shape of the fan and water pump was building up my hopes. Alas, they were dashed as I found that the cam chain guide and tensioner were only half there. The rest of the guide and tensioner were laying in the bottom of the engine.
Once the flywheel/rotor was off, I could get a better look at the damage. There was some munching going on between the the chain and the block. Guess I'll be pulling the front cover and cleaning out the sump.
Here is what I pulled out.
And here is what the parts should look like.
Back together with a new chain and valves timed.
Going to walk away from it for a few days and get back to finishing the spare room.
Stay tuned for the Mechanical Seal.
