How To Re-Seat Diesel Injectors | Prevent Black Death 

Thought it was a wham bam thing, now I know I need a injector well reaming kit. Thx for this!

Thanks! The Grease tip was a great one.

Excellent presentation and very helpful 👍

very good video make more... your very clear in your videos and helpful big thankyou!

Reaming is a bit harsh if done too enthusiastically, id soften with brake cleaner and use a suitable wire brush on an electric drill to remove the carbon, then vacuum it out. Always use OEM seals or genuine.

thank you very much.

great video pal

Nc Lods, Solid infos injectors reseat Thanks

That's exactly the problem i ran into... replaced the seals and washer ring.... and a diesel flows from the injection clamp... drill tap set is in the post.☆Happy new year ☆

Thank you for this video!

Very clear instructions, however, I have a 97 xj Cherokee 2.5 td with no. 1 injector sensor issue (turbo cuts out at 2000 rpm) so I need to remove it, check the t resistance and fit a replacement, would you have any tips for this, will I need a removal tool ? Never done this before 😬

Thanks mate.. Very informative video as im looking forward to clean my injectors seat.. 👍👍

Thanks pal

Many thanks for that. I am thinking about changing my own injectors on my Ford ecoblue engine, but as the injectors have been letting by I am wondering how I might clean the port itself?

Great video very informative peace!

Hello George. Great Videos, very intuitive and easy to follow. Many thanks for the content and your time. I recently replaced my rocker arms, camshafts, camshaft carrier, fuel overflow line and fuel return line. I Followed the ISTA manual to the T. I did not however ream the bottom of the injector wells. All the new parts mentioned were installed while piston 1 was on TDC. Timing was registered using a timing kit. Both intake and exhaust gears were matched up with the marks accordingly. I reassembled all the components but now the car cranks but doesn't turn on. The Camshaft sensor did get exposed to a degreaser and water unknowingly as it was on the valve cover and forgot to remove it prior to the bath. Do you think this is the cause of the car not turning on? It cranks once and stops it doesn't keep cranking to start. Could it be air in the fuel system or is the camshaft sensor cutting the system off to avoid more issues. I have 2014 535D N57 Engine.

very good informative.

Hello! Great video! I haver that tolo to reseat the injectors. Does anyone know wich One i choose for a Mitsubishi Colt VI 1.5 DID?

Hi I receipted my one and put new washer and cleaned out but for some reason I still have a leak do u no why this could be thank u 🙏🏻

W211 e220 cdi shall i use 17x17 angled reamer?

What if some carbon drops in the hole (and in the cilinder), is that a (huge?) problem ? And with the reaming-kit..? -> What about the little shavings this tools makes..?

Iv found black oil around my coil plug tops wonder if the oil cap would leak into the groves and down to the plugs If I need new copper washers can I do this with the engine in still

Hi George from canada I'm a trucker I'm having raw unburnt fuel out me stacks, and a load machine gun sound on me caterpillar 3406e any thoughts?

Alright mate followed every step of this exactly as you’ve done it but Iv got a problem with the claw that holds the injector down snapping anychance you know why this is happening

my washer ain't coming out. what did you use to remove the copper washer?

Has anyone tried Viton sealed "Dowty" washers? They easily handle hydraulic pressures and Viton is more than capable in a cylinder head.

Do the seals have a position or makes no difference?

Can this not be done under the bonnet? I don't really wanna take the engine out

hi..just, an idea maybe to magnetize milling cutter every time you cut a seating aswell as grease.belt and braces job..Very informative and encouraging video and save people loads .Retired ex workshop machinist.

Merry christmas

Merry christmas from korea^^

On a BT 50 is it the same?

Thanks for the video, followed the instructions, refitted reconditioned injectors, new copper washers, seals at the top of the tubes but now have no compression, engine cranks but sounds like there is no compression. If you remove the oil filler cap you get atomised diesel coming out. don't know what to try next.

What you called that tools??

I've done this now thank you. I was wondering, there is a small amount of carbon around the inside area of the bore(not the bottom) I tryed cleaning it but it's stuck on. Would this be a problem leaving it on as I don't want to risk trying to scrap it off and damage in bore

be nice to see a leak off test on this engine

best thanks for the instructions. Which grease is supposed to be used? Thanks.

Hi George, ive done the new manifold after watching your video. Very helpful. I have a big problem, itemoved the fuel metal pipes just to be able to access the cables. Now ive stuck them and bled the pipes. Car is still delay starting. Tends to crank up as if somethings wrong on the fueline.

One of my injectors is blown, on my x5 3.0 2008 m57 engine. I will order a used one off eBay, I was wondering if I would need to code it to my vehicle

Hi could you tell me are you removing any of the aluminium seat material? Or just carbon deposits on the seats? I had the black death occur on one of my injectors about a year ago, I cleaned up the seat with scotch bite on the end of a Screwdrier, as I didn't have the reaming tool and about a year later it's leaking again! Do I need to cut and remove seat material?

What happens if grease enters the engine?

It is possible that seat is minor air leaks then car won't start bcoz my car wont start

Is the purpose of teeming simply to remove carbon or to resurface the block that contacts the seal? In other words would a scotch pad adhered to a wooden dowel work as well? Also are there any seals which are more durable than the OEM seals. How do you clean the hold down bolt shaft threads? Great videos!

Great video, What type of grease to you use, does it matter?? Cheers

How do you know when to stop turning with the seat cutter tool I recently bought a 3.0 V6 mercedes and just discovered the leaking injectors .

Hi buddy I have a 2008 mk4 mondeo 1.8 tdci and one injector port was leaking it had that like sticky toffee substance I got the injector out do you know what size of Reem it would be for cutting it out. Also how did you make up the wee attachment to get down into it for the hoover cheers buddy nice work.

Did you reuse the injector hold down bolts or use new ones? I am currently doing this and on ISTA it does not mention using new bolts.

Would you increase the thickness of the new copper washer?

That work well for aluminum heads. Do you know of a injector seat cutter kit that work on cutting cast iron heads and where i can get one?

I cut the seats and replaced the copper washers on my bmw n47 engine and one is still leaking. What should I do next? Edit: I was running out of ideas so I swapped the injector with another and now they are all sealing. Also gently tightened the injector clamp, tapped the clamp and injector with a copper hammer and finally torqued to 25nm

That ceaning tool. Can i do this while the engine is in the car. Also whats the type of tool i will need to pull the fuel injectors out. Im selling the car this year. But want to sort some things out. I saw your common problems with n47 video and so far most of it is to do with high miles and time for egr cleaning so and so.

Hi! What brand you used for the washers?

it would be clever to make a tool that hooks up to the air compressor and the cutter will have a nipple that goes into the cylinder and the air pressure will blow the cuttings up out of the injector hole as the seat is being cut

Should run the reamer on the bottom of the injectors as well

Hi, most of the carbon fall in when I have the injectors removed... how can I clean inside the piston ? Thanks

Hello.. I have damage on the cylinder head where the injectors are sitting. The damage came when I was taking out a stuck coper washer. Will this method solve my issue? I think I will have to scrub a bit more from the cylinder head. Thanks for the help!

What do you mean by Black Death?

I use grease to lift the cuttings, best way to do it

What grease did you use standard multipurpose grease? Thanks

What are the type of injectors are on these engines? Bosch or Siemens?

Can you tell me where I can buy this tool

What if your engine doesnt have washers like my iveco?

What did you use to take out the injectors? Is a special tool needed? Link?

Hi Boss Do you know if after removing injectors you will have to reprgramm them to ecu ? Ford transit 2.0 tdci , fifa, 2004, 125 h Just wanna rmove injectors and have a look at them / clean them which i can manage but i wont manage configuring it all with scanner and laptop Cheers mate.

Loss of comp fkn nightmare

What engine is this? m47?

Is this the n47 engine?

Is there any symptoms of this apart from fuel coming back up? Would "ticking" "clicking" be a symptom?

Superb video, but the peace crap at the end is Fucking annoying lol

wrap a screwdriver a cloth and spray with carburetor cleaner and clean your injector wells than using very expensive tools that may damage your injector wells.

Don't think my mechanic did this just pickup up my 1.6tdi vw caddy. Fuel and oil filled all the top of Injectors leaking down engine now have oil pool. 😔 Once sitting it seem to drain back down. Injector 1

Awesome
