If two sides are not within those lines, then the tensioner is shot. I've been fighting this problem, even with new tensioners....

Something I noticed right off... why is the belt on the wrong groove of the SC pulley?

Because it walked off when the outer rib frayed off, caused by a failed pulley somewhere that was off-axis.

We say that..without knowing for sure.

Dbeast had put his belt on the wrong rib and it was making noise. In the dark on the way back from Florida.. we got it on properly and it'* stopped fraying since.

I need to hop on the recommendation for a couple cans of engine degreaser and putting the belt on properly..then watching if it walks over again. At this point..the belt is bad and available for testing.

It looks like a stock pulley which only has 6 ribs so it couldn't have been a groove off to begin with, correct?

If you are off one groove on the crank..which is tough for some to see..then it will work it'* way off a groove on other things as well.

If Dbeast can do it.. (uh..yeah..forget it..lol)

It'* possible this belt was off a tooth, it'* possible a pulley or tensioner is bad.

Hmmm..... The power steering pump in my 1993 SSEi went out too. My PS pump was spraying enough power steering fluid on the belts that the longer belt (It is on the supercharger, AC, and water pump) would slip off and get stuck behind the water pump pulley. It ate one belt completely and slightly frayed another. Not sure if your problem is the same as mine, but maybe your belts are slipping a little and that is causing the wear.
