Hey gang-
I've been driving the monty alot more lately, as most things in my life go bad, including my POS DD-
Anyway, took my boys out to the lake last weekend and used the monty to tow my little boat. Everything went really well, until pulling into the carport upon return. I heard this horrible knocking sound, and shut down. Seconds later, I get puffs of smoke coming from under the hood. I pop the hood and the smoke is coming from the vicinity of the turbo. Since we're home, and there's nothing I can do when it's this hot, I just leave it.
Well, I got a chance to look it over. The turbo seems fine, and spins freely, IC pipes are clean, exhaust pipe is clean. I start it up and everything seems fine, except for the knocking. I check the exhaust for coolant smell, and got nothing. As I watch the engine bay while it's running, I find the knock- The belt running the alternator and waterpump is flapping around a bit. I shut'r down and even though the belt seems tight enough, I get the sense something's wrong. It took awhile, but I finally found a section of belt that was missing everything but the cording. You know, the "V" part on the inside of the belt is gone.
Anyway... I know, long story, but when I loosened the alt to get the belt off, the bolt sheared off in the tapped hole int the alt. Not the tension adjust bolt, but the one which secures it once you tension it. I've always considered myself pretty good at removing stuck and broken fasteners, but even though I can get to both sides of this hole, I can't get it out.
Any thoughts on how it would be to drill it all the way and use a through bolt? I know it would require two wrenches, but anybody had to do this?
BTW- I'm pretty sure that the smoke was "residual" burnoff of maybe old oil and sludge and gunk on the outside. Maybe even the powdercoating that is on the pieces of aluminum that I built my heat shield out of. The drive home is about fourty miles and towing the boat, I was under load most of the way, boosting about 3-7 psi. I know the turbo will get pretty hot under those conditions.
I consider myself pretty lucky that the belt was still turning those last few miles home. I could easily see a bad overheat and blown motor <img src="/forums/images/graemlins/scared.gif" alt="" />
