So I've been trying to figure out why the timing belt tore on my 92 Talons TSI.
The engine has rust all over so that's one of the first issues I'm going to have to fix up with the engine.
This is what the timing components look like on the car.

I first thought that perhaps the oil pump had seized and caused timing belt failure but it spun freely, I did however feel a small amount of play on the sprocket that goes connected to the timing belt. Is this normal?
Then I though maybe the balance shaft belt went bad and took out my timing belt, but it was intact so that wasn't the culprit.
The hydraulic tensioner is rusted on the outside but there is no sign of oil leaks and on it and it feel sturdy but i have not tired compressing it. (I'm going to change it either way)
The tensioner arm that goes to the pulley did move freely about a half inch to an inch but keep in mind there is no timing belt on the pulley. Is it normal for it to move that much with not timing belt on?
And last but not least when I got to the lower timing belt cover I did notice that it only had the lower two bolts(marked with red arrows) on the rest of them were missing. So only the two bottom bolts were holding the timing cover onto the engine.
This is the reason the cover was rubbing with my accessory pulleys because it would wobble back and forth so much

I'm assuming the previous owner did a belt job and just lost them or did not think to put them back.
Also when I was taking the cover off I did notice that the cover was pinched up against the oil pump gear, where the timing belt would be. I had to use a wrench to get the bolt off when really a socket should fit just fine.
Is it likely that the timing belt cover pinched the belt so bad that it caused it to break? I don't see any sign of the timing belt wearing or eating into the timing cover..
I just want to make sure I figure out the problem before I start putting it back together..
Thanks
