Were do you get them? DO they really make a difference? My 300dt only has 119k on it, but from what Ive heard its a good idea to replace them every 100k. If the engine runs much better as they say they do, then Id buy them. I just dont know where to get them. I saw four on ebay though, and that diesel giant guy has em for a probably rip off price.

I got mine from diesel giant, they made a big improvement for my car....we put them on both of our SD's....they work great. Diesel Giant is probably the only place you will easily find them. And his prices aren't that bad.

I have an older FSM in German that lists pulling and testing every 100K kilometers (62K miles) I think the replacement was something close to that. FWIW, I have a set of Monarks - purrs like a kitten at idle and went from the characteristic diesel clack under power to more of a subdued thump.

with the ball inside the combustion chamber you can run the original injectors until the pop pressure needs to be adjusted by adding shims. that is around 300 k miles. spray pattern is no issue what so ever with mb. don't listen to any of dieselgiant's sales talk

One thing I've never really seen distinguished upon in these nozzle threads that grabs my curiousity, do these nozzles make a difference in an NA 617engine and/or would it be worth it to install them in one?

Pop (start of fuel ejection) pressure. NA = listed at 115 BAR, turbo = 135-145. Other matters like spray pattern, balancing, timing, etc. similar (but not identical) for the NA engines, too.

Do a search on this site for Bosio nozzles. Several members believe that they recieved better preformance from them. A I believe they are considered higher performance nozzles. I have seen a few other articles about them on the internet claiming better performance.
One member did say that one of his nozzles went band and he sent it to Bosio and was told it was the fuel (WVO) that he was using causing the problem. Better to look at those threads.

Yeah WVO will probably destroy any nozzle over time....they are not meant for that. Nor is the engine itself....

I have 5 new injector nozzles that I purchased from DG and never used - car is gone - I will sell for 25.00 each as a complete set (125.00) Thanks!

I would have a look at these...

Wow, that`s scarry. how many miles were on those combustion
chambers?

Did any raw fuel get down into the cylinders on the engine they came out of?

Yeah how many miles, because both of our SD's prechambers were in perfectly fine condition. One had 280k or so on it when we swapped them out for bosio nozzles, and mine had about 258k. All pre-chambers and pre-chamber balls were in tact.

One thing ive always wondered is if the clattering is a good thing. From what I understand, its the detonation of the diesel, causing a pinging on the cylinder walls. If it sounds soft, then that means that its a less powerful explosion right? Ive run a few gallons of vegetable oil through my car (with a setup under the hood like that when you do a diesel purge) for fun and noticed that at idle the clattering goes away also. With the monark nozzles does your car run better?

I'm not so sure loud always = more power. It still sounds like a diesel but it's smoother and more efficient. What you get when replacing worn out injectors = wide, stringy fuel jet, opening too soon even when the static timing is correct, inconsistent fuel delivery even when the IP is metering properly versus concise, controlled fuel jet delivered with good atomization consistently opening at the correct pressure for the correct duration. It adds up to the engine getting fuel the way it should. I need less throttle pedal to accelerate, it went from light smoke on start up to none at all and starting is just a tad quicker. To answer - Yes it runs much better but if your injectors test out OK I'm not sure you will see as big an improvement.
