I have a 1987 300TDT with 119,000 original miles bought a year ago from the original owner. Yesterday while accelerating abruptly in traffic I heard a loud wind up sound (like the turbo was out of control), a loud "clink" sound from under the hood, and a puff of grey smoke followed- all within a 2 second range. The rest of the way home (about 8 miles) there was a lack of power and that same wind up sound- only in the range that the turbo would normally kick in: My question is of course... What is it and how to fix it? this is the 603 Diesel 3.0L 6cyl. after letting the engine cool off it has the same symptoms while revving it in park.
