Question about 1995 Buick Riviera
Yeap your describing a supercharger bearing failure it'll lock up after a while, It can be rebuilt with new bearings but the directions aren't known to me as I've just replased the whole unit. The intake and waste gate gaskets van blow too and you can find the leak with wd-40 or carb spray as when you hit the leak it'll change the way it runs. You may also need to remove the crankcase vents and stop them up to see if you have a leak to the crankcase ( intake gasket leak) The normally assperated engine did this quite alot but theirs few less supercharged ones and I've only changed blown bolwers that won't turn and the cases were so scared up that they could'nt be rebuilt. Oriley shows a unit in thier Knoxville warehouse and it's rebuilt. Find the rattle and fix it and you'll save a ton of money as the repair may seem expensive but the new charger will set you back much more and the work is about the same.
