Non runner - “Engine just stopped”

 

So, a few weeks ago, I decided I needed another $700 project.  Owner had no idea why it stopped running. Sat for several years. 

 

When I got it home and after completely detailing it, I decided to check and see what was in the oil sump. Nothing,  but some very fine plastic bits. Nothing big and nothing metallic. Nothing suspicious in the oil filter. There is hope!!!!

 

Next stop, check the timing. Here is what I found on bank 1.....

 

It does appear that the engine jumped timing. I checked that “three letter” thing that everyone is paranoid about. All looked great!

 

I next pulled the scavenger pump cover off, to take a look at the chain/sprocket. Ah.....this could be a clue....

i think I found out why the timing is off. My guess is that someone was in there before to replace the chain rails and guides, but neglected to do a thorough check and left some bits in there. A piece got caught in the sprockets. 

 

 

This is is the result of that little bit of plastic:

 

 

Here is is what the valves looked like:

 

 

Now I gotta figure out what I’m going to do next. 

 

For those that have experience with this kind of stuff, what advice would ya give?
