I think I messed it up when I put the head back on, I got the belt too tight, and when I got back from test driving it, the pulley was making noise, and the belt was way to tight. Not sure on mileage though, the pulley and belt look fairly new. I didn't replace the belt for two reasons, one- that it looked great, two- that I was guaranteed to get it right, if I marked it and the timing gear when I pulled the head and clamped it in place to keep it from jumping a tooth on the crankshaft pulley. Yeah, I know, I can only assume, or hope that the water pump was replaced when all the other stuff was. I did put an analogue temp guage on the dash, and it runs at 200. I haven't looked in the Bentley yet to see the torque specs on the bolts, but I'm wondering if being that I'm only removing the vertical bolts, if they are re-usable, and the horizontal ones are the "torque to yield" kind that aren't.
