Mark,
Most of the rest of us need things like cam gear teeth, timing belts that stay in the right place and other minor details that work. You seem to have special dispensation from the gods of BWAAAAAH. They must like the way you drive!

What is the usual fix when the T-belt is running too close

there is a little tiny bit of play on the tensoner bolt. there is, obviosly the main washer, but ive seen PET drawings of a real thin washer as well. i think if i got rid of the slight amount of movement, radially of the tensioner, it would be straight on the roller . as you may know, the tensioner bolt has a thick body that bottoms out at the base of the water pump and that real thick washer. so, the top of the bolt with no washer, could be the reason for this. too think and there would be pressure on the bearing axially that probaby would not be good. but some .010 washer could clean up the angle slightly.
my belt runs to the front of the passenger pulley and pretty close to the front of the pulley, less 1/4" on the drvier side. it runs just over the edge of the tensioner roller. so far, no issues as it has always looked like this, over 5 race seasons and 18,000miles of street driving, 3 -4 different water pumps and several timing belts! and of course, NEW tensioner bolts. i had one break on installation and another was slightly bent over the course of 5 years. cheap insurance. that little big-headed (13mm) bolt, with the 10mm type threads, could be a real disaster! that bolt comes off and the heads are toast!

That belt is dragging on something. You can see the rubber sort of depositing (vulcanizing) in a liner fashion on to the top of the belt. If this belt only has 1500 on it, then there must be something (WP or tensioner roller) seizing up and causing this or it could simply have over 60K miles on it.

I guess I'll keep an eye on mine to make sure it isn't getting any closer to the front edge.
I would feel more comfortable with it running in the middle though, that's for sure!

Rog, is this who's car I think it is? A local Dr.'s car?
If so, I'd be really pissed off at the PO and that "shop".

I saw the belt in person, and it's either very old, or scuffing on something for a while. It just doesn't look right in there. The center cover isn't off yet so we can't see of the rollers are dragging or not.
