Manage to set the static timing with dial gauge. It was 0.91mm and I set it to 0.98mm.(slightly above the standard setting of 0.95mm). But the random fluctuations at idle remains together with the hot start issue. Is it the pump internals? No faults except that 'injection timing value out of expected'.
At same time, the starter motor play half dead when hot and I need to wait more than 1 1/2 hrs to get it started. May be the starter motor brushes need replacing.
For the first time during my ownership, the engine cut suddenly when reversing out of a parking lot. Waited till it got cooled down and the car started promptly. Is this event a signal on pending serious problems?

They talk about a worn pump and the remedy is to replace one of the covers (diamond shape) on the timing advance unit. May be our diesel experts can explain.
