Hello, I have a 90 TT. It has 128k miles. I bought it a couple months ago and been working on it. Replaced valve cover gaskets, cleaned stuff up,replaced a few other gaskets. It would start being jumped cause battery was bad, but power was barely there. Barely idled and got it going 25mph in my neighborhood in 1st gear. Lol. I'm pretty sure the drive belts have been changed and it looks like timing belt might have been changed. But I'm just learning. What do y'all think? I know it's an interference engine so I thought I'd make sure. Thanks Image

No matter what it looks like if you don't know for 100%, when it was replaced you need to replace it with a ,120k kit. If you are that far down in the engine go for it.
