Thanks for the response.
This is not a 'whine' but a bad rattle at one particular engine rpm, 2100. It sounds like a mechanical resonance. The engine has no unusual noises above and below this speed.

I sent this July 24, but it never made the list. I sent it again, same thing (naturally). I think it's ebecause my email provider changed so I will try the old one.
This may be relevant to Dennis's recent post about turbo whines.
About 7weeks back I posted a question "'93 turbo, 76,000mi: buzzy whine in synch with the engine, seems to be from the right side"
It turned out to be the timing belt tensioner pulleys; one worse than the other. Dealer found the problem, changed water pump, antifreeze, belts, oil seals, timing belt, and oil and charged three arms and four legs. They dropped the engine to do the work. I might have liked to do it but simply wasn't getting any round tuits. The pulleys whined even when off the car when he spun them.
