Hi, Steven! The video was really good! I would like to add some tips from my own experience: 1. After the disassemble of the fuel injectors, I recommend to put them vertically in a jar with concentrated drain cleaner and leave them in the jar for 2 hours but be careful, the level of the drain cleaner needs to not exceed the middle of the injectors (this will help with the opening of the thread and it helps clean the deposit much easier). 2. As the solution that I use in the ultrasonic cleaner device is concentrated drain cleaner and for the rinsing I use isopropyl alcohol. 3. After you assemble the components of the injector, before you thread it, put a small amount of thread blocker (this is going to help with possible future loses of fuel). Keep going with the awesome videos!

Seems a bit more complicated than spark plugs replacement. Thanks for the great video.

Who is ready to check their diesel fuel injectors for good operation, and then give them a nozzle clean? This is the new version of this video, and I’ve included some great extras that were suggested to me by you guys! If you do the leak-off test, and you find that the amount of diesel in each vial is vastly different, or if the amounts are a lot different to what you see in the video - then you should remove your injector/s and send them off for a professional rebuild using genuine Bosch parts, and a re-calibration (you will need to re-code your injectors after). If the leak-off test shows that there are no issues with the injector's high pressure ball valve then you may want to go on to clean the injector nozzles, to make sure that no blocked holes are causing a bad spray pattern. Your engine will continue to run reasonably ok with one, two, or even three blocked nozzle holes, but the resulting bad spray pattern will eventually cause wear on your engine's cylinder walls. It is the slow death of your engine. By doing this service every 100,000 miles, you can help your engine last much longer!

Hi, the leak off fuel is used to cool the injectors.

@jack504

Жыл бұрын

Short version: the low pressure fuel tank pump is pushing fuel out of the disconnected fuel bleed off lines. Long version: There's a low pressure fuel pump in the fuel tank that sends fuel to the engine bay. This pump moves more fuel than the engine needs even at full throttle, and most goes in a loop back to the tank. There is a T piece that sends a line off this loop to the high pressure fuel pump, so that it has a little positive inlet pressure and doesn't have to suck fuel from the tank. The injector bleed lines go back to the loop and bled fuel returns to the fuel tank. The bleed off pressure easily overcomes the low pressure in the fuel tank to engine loop and returns to the fuel tank. However when the bleed lines are entirely disconnected there is nothing to stop the low pressure pump pushing fuel out of the open lines, this is why his catch tank filled up so much.

@@StevenBTuner I've used water, a few cups vinegar, and squirts of washing up liquid on the advice of ...maybe Steve's Small Engines. To economise you can put pieces in glass and filled with carb cleaner (apparently; personally, I know nothing).

Do you have a video of removal and replacement of injectors on this model (looking for info on 2014 x35d engine) Thanks

Hi, it is on my list! Injectors can be a very real problem to get out, but fortunately the injectors in BMW engines seem to come out easier than most. The number one trick is to get the engine nice and hot before you start the removal, as the alloy head expands at twice the rate of the steel injectors, so it ensures that the injectors aren't clamped in metal to metal. However that doesn't make the job much fun for those fingertips...

Hi, very useful tutorial thanks for making. Just one question, did you have to remove the intake manifold to get to the fuel line nut on cylinders 2, 3 and 4. Cheers.

Hi, thanks! The intake manifold wasn't removed as far as I can remember. Another update to the video is that most of the time it should be possible to get the nozzle holes clean by suspending the injectors in an ultrasonic cleaner without taking them apart (first block up the fuel and electrical connections).
