Should I change the timing chain?

My car has 9k miles and sat for 10 years without driving. I don't use it much but would like to be able to without worrying. On the other hand I don't want to start turning bolts on a motor of a car that is all original including tires.


My third TTA I drove 240k miles on the stock chain then sold the car to someone who drove it home 3,000 miles. But that was years ago.

I think the sprocket has plastic gears and I have seen plastic gears fall apart and ruin 1968 cadillac motors within 22-32 years, depending on mileage. But it was always on a car with at least 50k miles and the plastic technology in 1968 was probably worse. Plus those motors run at 210 degrees all the time and the tta motors run 160-180.


Should I change it soon or not? How long do these things last?
 
Yes. Plastic (err Nylon) is plastic and it ages over time. I changed the one on the GN 3 years ago and it had plastic pieces already missing. I am lucky it didn't take the motor out.
 
I drove my car home and then then as soon as I got home, I changed the oil, then car would not start? I was thinking WTF? Turned out the last tooth on the plastic gear fell off. I sure was lucky to havemade it home.

So ya, change it for sure if you want to be safe and have reliability
