Sorry I missed the thread. I could have answered it for you right away! Had the same problem. The standard tensioner is junk.Well it turns out to be the Tensioner Pulley after all. Pulled and replaced the belt and while it was off I noticed a ton of grease on the bottom of the oil pan. I thought it was oil at first and then rubbed and smelled it. Turned out to be grease from the pulley bearing. You can see the black stuff and the smear where I rubbed my finger through it. Bought a new pulley and popped it on there and everything is smooth, squeal free, and I've got my lost horsepower back. Thanks again for all who posted replies.
