How many miles on the engine and injectors? I wouldn't think the lifters
would be an issue since the oil is thicker on start up and once up to temp
is when most lifters will make more noise.
Possible injector issues I would think. Double check all timing. Just for
curiosity what brand oil filter are you using?
All vw diesels after 1986 came with hydraulic heads that I'm aware of.

The '91 eco is sick. Extra noisy until engine is hot.
Ran some diesel-purge through it. Cracked the injector lines. #3 and
#4 seems great - hard running when cracked, #1 and #2 made a tiny little
difference in how things were running. Hmmmm...
No big gasket symptoms, but extremely rattly when cold. Power seems
I'm thinking there might be a hydraulic lifter not working when the oil
is cold (Rotella Synthetic 5w40 for the past 3 years).
I suppose the timing could have jumped, but is it likely to advance
This is my only VW diesel with a hydraulic head, the others are all
Re: lifters, what should I check for, and how hard is it to fix?
