How easy is it to check your BMW Bosch diesel injectors for good operation using a leak-off test and then clean the nozzles? Will ultrasonic cleaning work? Will high pressure washing work? What are the tricks to easy injector removal? How do we see the spray pattern to verify that it is good? How do we know if the needle valve is end-of-life? How do we make sure that our injectors don't leak after we install them? Watch and find out! This video applies to many diesel cars made between 2000 and 2007 that use Bosch electro-mechanical injectors, and applies specifically to BMW M47, M57 and M67 diesel engines from 2000 to 2007 (or so). This video does not apply to mechanical injectors or piezo-electric injectors (although there are many similarities).

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, 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!

An easy test you can do if u experience hard starting is to just simply remove the connectors and return line from the injectors and crank the engine, there should be NO leakage coming from the injectors, any diesel leaking from an injector doing this test is a bad injector and needs to be checked. Great vid :D Edit: this test is obviously only viable if the high pressure pump and rail is generating pressure to the injectors

@StevenBTuner
@StevenBTuner 7 месяцев назад
Hi, they aren't directly related, but if the glow plugs aren't operating then there could certainly be a bit more black soot clogging up the combustion chamber every time you do a cold start, which might end up in the fuel injector tips.

Hi, a full health check would start with error codes and then move on to a quick check of everything from the turbo (shaft movement/excess oil) to the intercooler (leaking hoses), and if you are removing the EGR then it could be the right time to make sure that the intake manifold starts of nice and clean, so that it can stay that way going forward.

The sleeve nut on the bottom of the engine can be EXTREMELY tight. I used an 15mm AF deep six-point socket and 600mm breaker bar. The extra length gives better control but it was glad of it.

Always buy NEW and ORiGINAL washers before this procedure. And don't forget to clean injector hole like shown in this video. Especially bottom part where your Cooper washer sits... Good joob man, liked, subscribed. I am glad you got rid of, mouth sounds from your earlier videos... Good job jebeno mljackanje :)

@@StevenBTuner Hehe, yes I guess you're right. Still I've used some diesel booster last couple of years, so it runs pretty clean. I just did the job with new copper gaskets and sealings on this car. Unfortunately the ones who did this job before me has done a left-hand job, so I had quite some struggles to do it properly. Now one injector are not working properly at low rpm / low load, ok at load, so I'll do the cleanup on all 4 and see if it helps..
@fiksefant
@fiksefant Год назад
@@StevenBTuner Feedback: All 4 had perfect spread. Surprise! No blocking, not even a slight hint of anything but a nice spray! I guess that diesel-booster I always use is doing the job. These injectors have been sat for at least 150.000KMs since a local Ford garage had the job with cleaning and replacing the copper shims... I'm quite sure they did not do anything but that job, no cleaning like you showed in video here. But... One of the injectors has been beaten quite alot, both by Ford garage (who gave up extracting that one) and now me when I after hours with heat, solvents and force finally managed to pull it out. I also found broken treads in one of the clamp bolts for that specific injector, so now Im starting the fun job with Time-Sert and see if that works fine. Hmm... Another reason never leave the job to "proffesionals", hehe.

@StevenBTuner
@StevenBTuner 3 года назад
Hi, thanks for watching, and glad you appreciate the detail :-) There is no need to re-code as this job takes the injectors back to match the calibration that is written on them. If the top end is disassembled then they will need to be re-calibrated. Clearing any fuel trim adaptations isn't a bad idea though.

Superb video, very clear. Thanks. I do have a couple of questions... I thought this leak off pipe was a one way thing for recycling"unused" fuel back to the pump. If that's the case why is there so much fuel coming back down that line and into your white canister.
@StevenBTuner
@StevenBTuner 2 года назад
Hi, the leak off fuel is used to cool the injectors.
@jack504
@jack504 Год назад
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.

One thing to say about cleaning injector holes in the head. DO NOT REAM if not necessary! PLUG THE HOLE while cleaning! So there is injector plugs ( a bronze/copper tip shaped like the injector tip with a threaded hole in the back). You push the plug deep in the hole and un-thread the rod leaving the plug in the injector hole. Then there is a fine brass wirebrush with a sleeve. Yo insert the wirebrush with the sleeve covering the bristles, then retract part of the sleeve to expose the bristles inside the injector hole on the flat surface and give it some twists to wirebrush the hole. Then with compressed air an a long tip you blow out all the gunk from the wirebrushing (the brass plug will still be seated and prevent any gunk entering the engine). Remove the plug by threading the rod on the back of the plug and pull the plug. Repeat for every cylinder. Reaming is needed if after wirebrushing there is pitting and score marks that could not be sealed by the copper washer. Reaming is quite bad, but as last resort may work. By reaming the injector will seat deeper in the chamber and can create a LOT of side effects. One of the worst side effects will be cracking the piston head because the diesel spray may wet the top of the piston causing a sharp cooling before ignition because the injector tip is much closer to the piston. I have a whole set of iveco truck pistons all of them have 5 cracks in the omega chamber of the piston aligning with the 5hole injection pattern. That truck head was reamed several times and the injector was sitting 3mm deeper than intended. those 3mm made this cracking possible. And by cracking i mean deep cracks and in several pistons even blown chunks of the omega chamber with huge loss of pressure under the piston creating major problems in the oiling system and PCV leading to runaway diesel engines and may blow up the turbo from improper oiling with contaminated oil and aerated oil from the huge crank pressure. All of this for 3mm of ream in a 120mm bore engine for a truck. In a passenger car tolerances are much higher (for the much smaller bore and stroke) and 1mm might create similar problems. So do not ream! and if you do, compensate with a thicker copper washer to sit the injector tip at precisely the right height!
