The car is a 92 talon tsi awd 6 bolt. I honestley have no clue what happened it ran fine for 2 min them i tunred it off to check its and this is what I saw, there was no werid noise or vibration all the timeing marks lined up again, this was a brand new mitsubishi. There is no apparent thing that the belt would be scraping on.

If you still have the lower cover off I would slowly turn it over by hand and try to find where it is rubbing. Is the tension set correctly? I mean, not by feel, but with the special tool to allow you to torque the pulley, because if it isnt, it could walk up and down the sprockets and rub that way, or worse, skip a tooth while driving....

I've heard of one of the oil pan bolts being either too long or backing out(dont remember which it was). But either way, they would rub on the timing belt which is no good.
Just something else to check while you're investigating

Good point. That happens mostly from losing a bolt and buying one from the hardware store, then being unfortunate enough to install it on the far left side of the pan.

Are you inquiring about the wear on the backside of the belt? Aside the oil pan bolt being to long would a rusty surface on the idler and tensioner pulley cause a a semi gloss look on the Tbelt?

Here ya go.

The red circles are bolts that could have backed out and would be rubbing against the belt.
The yellow square shows the plate that bolts the upper T-belt cover to the front of the engine. This plate is thin aluminuim and can easily bend.
The yellow circle is the crankshaft sproket. If its not bult all they way down then it will rub against the belt at about the 5 o' clock area.

Check these areas first.

Last two things it could be is bad tension and/or a bad belt.

Hope this helps.

Note I provided a picture without editing for clarity.

edit **sorry my internet timed out and the pictures didn
t add, but it looks like you didn't need them anyway.

Hey guys I figured out what was wrong, the backing plate (the one with the timeing mark on it) for the crank sprocket was bent in one area comnig in contact with the t-belt ripping it up. I somehow must of missed it when i rotated the engine by hand before because I can clearley see it now.
