1983 300D Turbodiesel - Diesel Purge Cleaning

Good morning:

On a 1983 300D turbodiesel (W123), is it better to perform a valve adjustment before or after an engine diesel purge?

Thanks for your help.

Is your engine running rough?

If your engine is running ok won't make any difference. But If you want to see how much affect the valve adjustment has on your engine, do the valve adjustment first, then run the engine to test for improvement- then do purge.

I would do the purge first.

I would do the purge first. Then do a test drive, get a feel for the acceleration and power.. Then perform a valve adjustment. Spend the money and get the special curve wrenches.
