After Bosio nozzle install
Yesterday I finally got around to installing my injectors fitted with Bosio nozzles. I have learned an incredible amount of information from this forum, so thanks to all that have responded to my posts.
First of all I would like to say what a difference these injectors make. To set the record straight my engine was running well before I did this. To date with the electric fan conversion, fully synthetic oil, Fitch fuel catalyst and K&N air filter I have averaged 29MPG combined city / highway mileage. It only made sense to me to go the extra mile and install these injectors fitted with the Bosios. The actual process of removing the injectors was a bit tedious but not too difficult. I know some of you will chastise me for doing this..... I had to leave in 3 of the 4 heat shields.  I tried and tried to get them out but only cylinder #1 came out. I didn't have the time to wrestle with the other 3 so I bit the bullet and went ahead and left them in place. After removing the original injectors I noticed something peculiar. To my knowledge an OM616 comes with 115 bar injectors. The ones I removed were 135 bar. At this point I figured things could only improve due to having the wrong bar injectors installed. I was correct on this assumption because my engine runs much better. I understand this might be due to the new nozzles and the injectors being pop tested, but I'm guessing it's better to have the right injectors installed. So now I'm going to do a sort of long term test on the potential fuel mileage increase. So far I'm super satisfied on the difference they make. The engine runs smoother, starts up faster, and has more pep than before. Not to mention it sounds quieter and has much less startup smoke. I recommend Bosio nozzles to anyone looking for a good upgrade to their Benz diesel.

How long did it take you to complete the change?

The nozzle "holder" has little to do with the nozzle or pop pressure of the actual inj. It is simple a core that was likely rebuilt; do not automatically assume they were the wrong inj for your engine. Looking at teh nozzle and then confirming pressure setting is the only way to know for sure "what" application they were set up for.

It's a fairly simple job. All I did was clean the cover with paint thinner and a rag real well. Then I used a cordless drill with a wire brush attachment and went at it for about an hour. I then painted it with Duplicolor Detroit Diesel Alpine Green high temp engine paint. I used pretty much the whole can and that was good for 5 layers. The oil cap was shot with some generic black paint.

Painting it DD green WILL make it leak oil, Detroit Diesel has proven that many times.
