- Here is some useful information on how the om606 injectors operate and if and when you should rebuild them.
To buy some Dieselpumpuk injectors see below

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.
That’s interesting information Thankyou for taking the time to share.
@@DieselPumpUK I can send CAD files if desired.
All mechanics should know to slide washers and nuts into holes and into studs with a screwdriver. Never miss again.
Thanks for coming to my Tedtalk.
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.
never mind Lukes knowledge .. we need to hear more of his camera-persons tuning tips
i bet there are people jotting that down as well. loctite for higher horsepower. :)
Love your channel
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
Imagine how sad I was to find out only 20 odd OM606 powered mercs got delivered into Australia
Can you make a video of changing valve springs and why? (:
thank you
What nozzle brand do you use in your rebuilt injectors? What size, 310?
Could you please guide me on purchasing your diesel return hose?
Do you reckon ceramic coating those components might be beneficial?
Does N/A pre chambers effect performance on high horsepower build?
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
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.
What do you think of me putting one of these into a Miata?
I will produce some prechambers in the future
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.
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
@@DieselPumpUK is there a torque spec for those? Of course impossible to get socket style torque wrench on them.
6:20 How much power will be greater, or economy, if you switch to common rail?
Loctite for more BHP!😂😂😂
I like the clear ones. You can watch the diesel flow😂
Sintered Tungsten pre-ignition chambers? 🤔
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!
Hey, congratulations to Vlad (dammit, I didn’t win) but who in and around Montreal, Canada sells aftermarket engines and parts for the OM606??? I have a deep neeeeeeed to have one in my first gen Nissan Xterra! Do you all have any leads?
Since you build and sell crate engines, ain’t it hard to find engines to rebuild?
Before this I was thinking of
Gasoline Port Injectors
Gasoline Direct Injectors
Diesel Indirect Injectors
Diesel Direct Injectors
Pros and cons of each, maintenance, efficiency and reliability
E300 injectors is a pain to remove them. The injector manifold is made from 6061-T6. Injectors are made from steel, Geez. Who's won that battle.
I've never had a problem
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
I'd love to know this ... !!
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.
@@Skul-Ski mkay , I wanted to do that anyway. But thanks
That fuel goes fast. 150cc x6 = almost litre in such a small time. 10seconds?
I damaged and burned two times Mercedes genuine heat shild and after that I installed vw heat shild and I forgot that kind of problem forever..
It’s good to hear your experiences, what was causing the failure and was it one cylinder in particular?
Three of them was burned number 4,5,and 6.but now ecerything is ok.I have installed your 7.7mm injectors.
What Part number are you using for the VW heat shields?
How capable are the common rail #OM603 motors ? Comparibly..
Just because it would be awesome, what really prevents you from building your own billet or cast pump or engine? Only cost or difficulties in the design process?
They do have their own billet pumps.
@@MrAndrius12 I thought so but wasn't sure, my bad.
Guten Tag. kann ich so ein Motor bei euch kaufen ?
Inconel cups?
Good idea !
17:23 ummmmmmmm🥴
Good pre-chamber, bad pre-chamber; _UGLY_ pre-chamber !
What happend to the patrol?
Not all shirts have been received yet
Thx, really looking forward getting a update video
Can an NA 606 be turboharged? To how much power? I've been searching for answers for ages 🥲
Yes you can!
@@DieselPumpUK thank you for answering!!! Can it be done with your billet pumps or kits or is that overkill for the max power the internals can handle? Do you know what is the max tested reliable power the NA can handle? Again thanks for replying
