You also know what a Singer sewing machine sounds like.
Your tensioner damage is not that bad. A good degreasing, welding and some remachining should take car of it. But wait to see what the valve seats look like. Also the valve guides.
Did you check the chain sprockets on the cams? They might be missing teeth.

Aaargh. I'm so sorry to see this, Albert! It's no use now, but for some reason I was under the impression that you had owned this S2 for a while or I would have told you about the tensioner pad issue. It was the first thing I replaced when I bought my S2.
Luckily, you're in the U.S., where there are a lot more of these cars being dismantled that you can buy used parts from. If you were in Barcelona, like my S2, you'd be much worse off!
Good luck, and be sure to check the Rennlist sponsors page for dismantlers if you need used parts.

Ouch! I replaced my tensioner within days of driving my S2 home. At 100k, I was worried if I delayed, I'd get...well, what you got!
Good luck with the repairs.
Goes to show--you HAVE TO REPLACE THE TENSIONER, or at least the pad, or else!!

When chains are used in an industrial design a sprocket is used as the idler. Like the idlers for the timing and counter balance belts.
Why in heck Porsche used a plastic pad is beyond me. Seems like a design update is sorely needed.

It's considered one of the wearable items that will outlast the designed life of the car. (~10 years.) Mercedes and Nissan used the same design in their engines from 20-30 yrs ago. I'm not sure about now though. I think engineers also had to look at the cost of production. It's much cheaper to use a phenolic pad than a steel pulley.

Nissan used that design in the 200SX, Pulsar, Stanza etc. You cant count the number of those I have f*d with. It pays 17 HOURS to do the chain. I have personally bought and sold about 5 Stanzas that had it break and ended up needing a head.
