My 86 GL wagon used to eat it's timing belt idlers. (I don't think they take well to mud.) They're about $100 each at a parts house, so I always went to the wreckers for my replacements, at a whopping $5 for the set. A few sets later I was fed up with it, so I welded plates to the pulley faces, and installed grease fittings. I'm still using that set. I'm not impressed with the factory seals on those things.

My idlers always used to sieze. If it was an outside idler (tensioner,) I'd hear a squealing noise and see smoke - unless it was a wet day - then I could drive all day like that. If it was an inside idler, it'd buzz for about ten seconds and then derail the belt.
