The problem i am having is with my 1987 300d rough running and smoking on cold startups, i have changed all 6 glow plugs and verified there operation the car starts snappy almost the instant the starter turns over.. it just bucks and shakes and smokes white/blue smoke for about one minute...i dont think it is a compression issue due to it will start even if you for get to wait to glow it will just run rougher longer than a minute...I suspect it could be caused by severely worn nozzles possible original for all i know..i pulled all 6 injectors and cleaned and reassembled.. three of the six had seized pintles that i was able to lube and exercise in diesel till the moved freely re-installed with new shields and the car runs better warm..very smooth hot idle with same nailing it has had since i bought it...but no improvement on cold startups...i guess my real question after my ramblings is.. do you think new nozzles and balanced injectors will resolve the cold start ups issues as well as the nailing..or is there something else i should look at first..
Oh just to add it started a little rough in the summer also just it only lasted 30 secs or so and smoked less..and the smoke smells like raw diesel

Thanks in advance

Arlo
