It has made it 30,000 and aparently it will go for a good while longer.  |
When I bought my mercedes it had about 190K on it. Mine ran rougher that I wanted at Idle.
Since I had a Chinese Pop/Nozzle Tester I bought back in 92 when I got the Volvo Diesel I pulled the Injectors (they appeared to be the origionals) I tested and rebuilt them myself.
On all of them the central drilled holes were plugged with Carbon. There was a lot of erosion of the exposed metal between the Pintel and the Injector Heat shield and 3 where what I call dribblers (indicting that the seating area was shot); all had poor spray patteren.
Rebuilding them with new Spray Nozzles did a lot towards smoothing out my idle.
Below is a pic of the Stock Injector Spray Nozzles with the holes drilled in the pintel. 1 down the center and 1 acrossed. On mine both were plugged with Carbon.
That area of then nozzle works at idle and low speed and fuel quanities.
Just above the cross drilled hole at #14 is the Pintel seating area. When that area wears unatomized fuel will leak out before it is supposed and not burn well; it also detracts from the atomization of the rest of the fuel when the Pintle opens.
While under hard exceleration most Diesels will put out a little black smoke; I think this is normal. But, it should clear up and not leave a big trail of smoke behind it.
