 |
|
Just curious what others have experienced ? I've owned three early ( 1980 to 1991 NA ) VW diesels now but never went over 200,000 miles on any of them and never had any pump or injector problems .
Also owned 3 old Mercedes diesels with lots ( about 300K ) of miles but never any pump problems , not even sure how I would tell if pump was going bad ?

Usually you will have rough running at idle when the pump is really worn and should be replaced.

My 85 Jetta had 470,000 kms on the motor when I replaced it due to low compression and the injection pump was still working fine.

Does Canada have the ultra low sulfur diesel or the high sulfur for Highway use , what we call off road only diesel ( farm use ) and how often do you change your filters . Thanks .

We didn't have ULSD when the original motor was still in it. As far as filter changes, I don't know how often the previous owner changed them (I bought the car with 360,000 kms on it) but I don't believe I changed it at all in the 110,000kms I ran it.
Unfortunately, I've read that the ULSD does reduce the life of the seals in the older pumps.

| Typical failure on old pumps is they start leaking in the shaft groove (easy fix) and seals, but overall very reliable |
