This 87SDL is at 97K miles so I figure at 100K I need:
* XMission service
* Timing chain/tensioner
* AC system flush (? - want to be careful - I'm in Texas)
* (what else)?

I use:
* Mobil1 15/50
* Texaco premium low sulfer diesel

But here's my REAL question. Ever since trap oxidizer removal, it smokes too much for my liking when accelerating past 3000 RPM (grey smoke). It starts/runs/idles smoothly and there's no oil consumption or coolant leak prob.

Have tried:
* Techron
* GK40
* K&N air filter

I want this car run as cleanly as it possibly can. I've heard that new injectors always help at this age

Any suggestions for unusual but documented exhaust arrangements, intake arrangements, additives, timing/injection arrangements, etc. are appreciated.

Thank you.

CRote,

I have an 87 300SDL just like you with 100K. You do realize that when you accelerate hard on a turbocharged diesel engine, it will smoke. Mine does the exact same thing; there is nothing wrong with the car.

First of all, what has been the service history of the car? When were the fluids last changed (engine oil, transmission oil, coolant, brake system, power steering)?

With the mileage on your car, the replacement of timing chain, tensioner, a/c flush are not needed unless there is something wrong with the car. The service manual doesn't list anything with a mandatory replacement of the tensioner or a/c flush.
