I found a better way to drop the washers into the injector holes. Put the washers over the shank of a screwdriver. Hold the washer at the handle of the screwdriver. Insert tip of the screwdriver into the hole. Let go of the washer. That way it can't flip.

Great idea

Pre-chambers are made of at least 3 different alloys that are friction welded together. The very tip of the prechamber is made of a nickel super alloy, likely Nimonic 80 or 90, the main part of the body is a different stainless steel alloy but is slightly magnetic, the front isn't The very end of the prechamber where the injector screws in is made of some kind of non-stainless steel. Also I have a OM605 turbo I'm rebuilding where all the prechamber balls are slightly bendt down and crooked, not flush with the other side of the pilot hole, it has vibrated on that side and enlarged the hole slightly along with slight contact corrosion. I'm making some new prechamber balls out of Inconel 718 with enlarged ends so it can be machined flush, but prechamber ball stuff can apparently be a issue with high milage engines. Prechamber balls aren't made of a superalloy interestingly, as they're pretty ferromagnetic.

Love your channel

Funny, I've had a similar idea. Maybe you'll do it first so I don't have to. Make a fitting between the injector and pump that lets you tee in a 500 bar (or higher) pressure transducer so you can watch the actual dynamic injector pressure. If you had all cylinders monitored it would also let you know the injector and pump health. The way computers should be used in cars imo... Monitor the health, not control things. A while back in a chat you said the prechambers were just steel, but I have a feeling the tips are something like 330 stainless or some flavor of inconel. If you hit them with a magnet you'll notice the tip isn't magnetic, but has a higher permissability than air so it looks magnetic. I have still yet to send a prechamber to a materials analysis lab, but I do intend to. Thanks for the video and sharing the info! I would love to see a video on the 180mm vs 210mm diffs you can put in the W124 if you are looking for more content ideas.

thank you i learned a lot

whats the difference in terms off efficiency between the 2 technologies and does runing bigger pumps etc increase efficiency as you can get more diesel in the chamber at better intervals ? thanks

What nozzle brand do you use in your rebuilt injectors? What size, 310?

Can you make a video of changing valve springs and why? (:

Could you please guide me on purchasing your diesel return hose?

Do you reckon ceramic coating those components might be beneficial?

How can you test for bad pre chambers with the engine in your car? My 1998 E300 TD has clouds of blue smoke and misfires when you hold the rpm at 1600 while parked. When you increase the rpm to 3000 it clears up and runs smooth. I have no air bubbles in the lines. Under power up hills it runs smooth. I have replaced clear fuel lines, O rings, primary pump, primary and main filters. I am thinking maybe cracking the injector lines one at a time while at 1600 rpm to see if it is isolated to a cylinder. I do have a new set of Bosch injectors I could install. They would be set at 135 bar. Would it be a good idea to have them set to 150 bar before installation? My car has 429 k all stock except for potentiometer modification. And yes, the car had the same symptoms before the modification. When I adjust the potentiometer I can do a long burnout with lots of black smoke. It seems like it is not a shortage of fuel.

very interesting - thanks for the vid. Question I would have: isn´t the increased opening pressure of 150bar reducing the total amount of diesel as the open intervall gets reduced? Have you made measurements comparing f.e. 120 bar with 150 bar? Another question: why is the use of the washers limited to only one time (heard this from Mercedes? Thanks and greetings from Germany, Frank

The washers are of a soft metal which is a one use due to the torque applied which crushes the metal

Does N/A pre chambers effect performance on high horsepower build?

What do you think of me putting one of these into a Miata?

Hey Luke I'm getting ready to pull my injectors for my 606 what is the reason your deep socket has the notch cut out. Of course I'm here in the US and I can I find a 22 mil deep socket in my toolbox so I'm going to order one does it need to have that notch

Hi. He called it a Lambda socket (oxygen sensor socket). They have that cutout for the wiring of those O2 sensors. Hope this clears it out. Cheers!

I will produce some prechambers in the future

Ever heard of any other reason for fuel pooling up into the injector wells other than bad hose? I have replaced hoses at least twice with the OEM style braided covered rubber but still have a good bit of fuel always in the wells. Truth be told, I installed rebuilt injectors and scoured the internet for proper torque setting for installation of the injectors and found that I WAY over torqued all the injectors. Wish your video was up before I replaced the injectors. I did remove them all and re-installed them to proper torque with new washers. Engine runs just fine, but still plagued by the constant pool of fuel in the wells. Have it running in my head that maybe the over torque might be the cause, but I kinda doubt it because that would probably mean I would have had to crack the injector housing for that to be the case. And if so then there should probably be a flood of fuel since it would be at 135bar at any potential crack. By the way, there are multiple sources out there that say to go to 40Nm and then another 90 degrees WRONG. I know this now. It felt wrong when I was doing it. I did not go that far but I did go 45 degree past 45Nm.

Most common reason for fuel in and around injector is the injector high pressure hose connection at the top, not seated correctly or ferrule worn out due to over tightening etc

it is kinda funny when it comes to rubber fuel hoses a lot of people will say this and this brand sucks never buy, but they rarely say what they think you should actually buy :P maybe i will try continental have tried all sorts of brands on my mtdi and well it is only a matter of when and not if they will start leaking.

As always fantastic video. Just wanted to ask if you have ever fitted a 500bhp+ om606 into a w204 with the standard om642 removed ? I just wonder if I'd need a new box etc as I doubt it could handle that much torque and bhp. But I've always said if my engine ever goes tits up and it's a major cost I'm just going to take it out and hopefully fit the 606. Cheers mate

Hi there , I recently bought a 606 and have the following problem. when it runs constantly, i have something like ignition misfires, it runs very quietly and then the engine chokes once and continues to run quietly. and at 850-900 rpm it also jerks. I would be grateful if you could tell me possible causes.

More than likely air getting into the fuel lines. replace all the little plastic fuel lines around and under the intake manifold. Plenty of videos on that. Also might need to replace the feed and return line from the tank if they are original they are more than likely quite old and brittle. I have a video on my channel about those with part numbers. But start with the little clear plastic lines first.
