Try a slightly shorter belt.

I actually purchased a shorter belt, but whilst it may solve my problem, it isn't "correct"

Looks like I have the solution.

Many thanks to Callaway cars and Boostedmaxpsi

Turns out the 1987 used a different method to lubricate the turbos.... apparently a pump mounted to the front of the power steering pump.
This turned out to be not a great solution and in 1988 they changed it to a pump mounted to the serpentine belt tensioner
See cut & paste from relevant section:
1987 cars had a pump that was driven off the front of the power steering pump. This pump is obsolete! If you see one of these on a car call the factory immediately. All cars should have a scavenge pump that is integrated with the accessory belt tensioner.

So the 1987 should be using a 1988-91 serpentine belt tensioner (the 1987 one wont fit).

I have one on order and will report back once its on and working.

Hope this helps all 1987 CTTC owners as well as 1989-91 Owners

Is 2250MM the correct length belt for 1989 as well?
