This is true. I will keep everyone updated on how they work out.

I don't have a problem rebuilding with new nozzles and paying someone to pop them only for me.
$50 for all 5, cleaned and popped. They tested fine after cleaning and were in spec when popped so no rebuild needed.... RT

Put the Bosios into my NA 1980 300CD tonight. Nailing like mad on #4 where it didn't before. seems quite rough at idle and not much power. That major nailing gets me. She was a pretty good runner before--just thought the Bosios would be better--had originals in her for 250000 or more. Had done IP timing some time ago. It shouldn't have all gone to pot in the hour it took to do the swap. What the heck am I missing??????????????????????? Original nozzles looked pretty good too, not all crapped up like some shown.

Check the part numbers carefully as I said earlier in this thread. I had some nailing with the Bosio knozzles for the first couple of hundred miles. I just put in a new set of Bosch knozzles in yesterday. I have no nailing, smooth idle, smooth power band and it seams quieter than before. Make sure you use new heat shield washers each time. They are a crush type washer that should not be reused. Chances are you did not need to replace your knozzles. I'll be taking it for a longer ride today with the new bosch knozzles just cause it's a nice day, cold but nice.

Good luck

Bosio

Thanks for the suggestion. I
ll check them out carefully. Yes, it is possible I could have gotten away with a service tech cleaning and pattern check.

I hope there is a good explaination for the difference--and why do some seem to be having the nailing problem?? Better ignition characteristics or earlier popping-off???

BTW, a query to Diesel Giant hasn't had a reply yet in a few days. will this be a problem?

Bosio

In the early morning hours I often wake up with a dozen ideas going around in my head--one of them was that a speck of dirt would keep the injector pin from closing properly and when the pressure came up from the IP it would spray prematurely causing nailing. Then, afterward it would continue to dribble---like some of us older guys----and cause the smoke. time to go back into #4 and see what we see. I dearly hope it WAS just a piece of junk of some sort--clean it and problem solved.

Thanks for all the info read in this and other postings.

Update. I gave a call to Russ before takeing the bad injector out. He said he'd bet that a pin under the spring got reversed. I checked it out and sure enough, that was it. The whole body was full of black goop---carbon etc. The needle was stuck and it took a bit of cleaning. I'd guess that with no resistance on the needle, the cylinder compression was pushing fuel and crap back up into the injector body. No wonder it was smoking.
Back together, everything is rosy. NO smoke and even combustion except for a lope that I think is valve adjustment. I probably could have gotten away with a cleaning and check of the old ones but I may get a bit more mileage with a better spray pattern and that will be worth something. Timing is in order also and with a tweak here and there it may surprise me.

Thanks for the comments.

Sparky
