I have had 17 VW diesels. I have had engines all apart have been in Injection pumps have and injectors, i adjust my own valves etc. I am not saying this to look like a hero just to equate you with my mechanical aptitude. This problem stumps me. I have 2 vw diesels both NA. One is an 85 mechanical lifter and the other is a 91. I have had the 91 about 4 years and after owning it for about 18 months I noticed that I started getting a significant soot buildup on the trunk. The car burned ZERO oil. I had put a rabbit style fuel filter on it but have done that on many of my diesels with no issues. I loved the big bumper body so I decided to trensplant the great running m85 mech motor into my 91 body. The 85 motor didn't burn oil, had great acceleration and no soot. So i made the transplant and now the 85 motor produces soot and the 91 motor in the 85 body does not. The 91 body has always needed about 2 seconds of cranking to start unless it is the first start with glowplugs. I was frustrated as heck at Christmas so I ripped off the water separator under the car and plumbed the lines together. I am lost as heck. Swapping motors in 90 degree weather was not a bunch of fun and i still have the problem. Thanx for any help.
