This may shed some light on what is going on with my wife's car. It is a 1987 300TDt and was running pretty good except it lacked power. It has always cranked well in the cold, even down to 18 degrees. I checked the pump timing with the pump lock tool and it was at 11 ATDC and I adjusted it to about 14.5 and it made no difference. It had also started smoking really bad at cold start and was even more anemic than usual. I checked the resistance on the glow plugs and they were all under 30 OHMS (The FSM says as long as they don;t read infinity they are good) except number three that was at 3200 OHMS. I had a spare and thought I could pull out the bad one and have a new installed in 15 minutes. The lead came off easy enough and I unscrewed the glow plug but could not pull it out. It is tight quarters with the intake plenum still on but I was able to get a pair of pliers in there but still could not pull it out. After playing for a while, trying not to pull of the intake plenum, I ended up pulling the plenum and prying the glow plug out. Here is a photo of the culprit.
The injector lines were also a mess so I pulled them off and pulled the number three injector and prechamber and noticed that the ball was missing. I had a spare prechamber and another injector (untested) and put it in with high hopes that if would stop the smoking at cold start. It did not. I had already done two liters of dieselpurge and that did not seem to help either. I have been super busy lately with other things, but know that before it is all over I will have to pull the intake again as well as all the injectors and prechambers and check them as well as doing a compression test. I am waiting for the compression tester to get here and I am shopping for a pop tester now. It will cost a few dollars in tools and some hours of labor but it will be done right and cost much less than any shop would charge me.
BTW, I was able to vacuum out the combustion chamber very well with my shop vac. When I was cleaning things up after I pulled the prechamber, some junk fell into the combustion chamber and I was could see it in there. I got the shop vac and sucked it right out.
