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.

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 😬

[@edgarmartinez2328]

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.

Are your hold down bolts tightening up? The holes fill up with crap and doesn't let the bolts seat properly

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

[@GeorgeAusters]

Wouldn’t worry too much but clean what you can with brake cleaner and a rag.. The bore doesn’t need to be spot on as the seal and o-rings seal it anyway

[@QuattroBajeena]

@@user-vo8ij2jj4r it was the crankshaft sensor, it stopped working, when i was bleeding the fuel line on the injectors. It created misfires and burning fuels slow on acceleration and delay on start up, once that was changed, it came back to life.

[@davidrobbo27]

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?

[@GeorgeAusters]

In theory there’s no need to remove material but doesn’t hurt to remove a tiny bit. Do you replace the injector seals?

[@carclips6401]

What happens if grease enters the engine?

[@raghavdevda3542]

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

[@mikeshankin5494]

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!

[@GeorgeAusters]

Mainly to remove the carbon and make sure it has a clean seat

[@Trenislife]

Always ALWAYS replace the hold down bolts. They're stretch bolts and can only be torqued down once. Definitely buy a set of brand new ones.

[@davidelliott5843]

@@Trenislife Many engines have one M8 stud holding two injectors! These absolutely have to be replaced. The Fiat type look very weak to my mind. It makes me wonder if high tensile studs would do a better job and why the factory uses the special bolts..

[@davidelliott5843]

@@GeorgeAusters If the injector seat is clean and unmarked. you really should not need to recut the surface. A close look with a USB inspection camera "borescope" might be worth doing.

[@robertashdown4984]

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

[@GeorgeAusters]

Something heat resistant like copper grease

[@mariolourenco5885]

Copper grease is only good for when both metals are the same. That head is aluminium if I'm not mistaken. You are better of using ceramic grease it's heat resistant upto 1400 degrees.

[@davidelliott5843]

@@mariolourenco5885 I've used a copper/carbon high temperature anti seize paste to great effect. It's worked really well between stainless and aluminium and on exhaust studs. It should be more than enough on a diesel injector. Having got one to deal with right now, I'm sure coating the injector all the way down would have prevented the problem happening.

[@koysiimiah3320]

​@@davidelliott5843do you apply grease on the whole injector as well before installing so it can come out easy and not rust? He doesnt show how to clean the actual injector or do you just wipe it and spray with carb cleaner only without brass brush to clean injector body and tip?

[@ecojet8384]

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.

[@GeorgeAusters]

Original ones

[@mikejohnson7768]

Would you increase the thickness of the new copper washer?

[@GeorgeAusters]

No why?

[@ssss-df5qz]

@@GeorgeAusters I suppose they're thinking that taking a few thou off the seat would impact the pressure applied to the injector by the clamp and bolt. It's a pertinent question, but I can't see it being an issue. I'd probably go 5 degrees more on the bolt on a heavier cut personally to be sure but, thinking about it more, because of the way injectors are generally held in by spring tension from the clamps, it should be relative right down to the torque and angle requirements.

[@sweetthing3914]

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?

[@GeorgeAusters]

This will work fine. You’re not trying to cut the head much, more just clean it

[@zensempai7371]

​​@@GeorgeAustersjust make sure you can see the metal seat clean , is really all you need to do.

[@dominikkozela9763]

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

[@QuattroBajeena]

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.

[@oskarsstankevics7863]

Hi! What brand you used for the washers?

[@GeorgeAusters]

Bosch only

[@texas77563]

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

[@Timbo5553]

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

[@GeorgeAusters]

Yeah not a bad idea!

Gabriel Alexandru Cisma Watch my video stripping down n47 engine👍🏻

[@davidelliott5843]

They should simply pull out. A strong solvent might help on some stuck injectors but the only sure way is a proper jacking tool or slide hammer to pull them out. It's a shame the injectors are not made with threaded lugs for jacking bolts.

[@SuttonCourtenay]

If you have the black death problem and the injector is stuck then run the engine to get it hot and this should help to twist it back and fourth to break the black glue

[@SuttonCourtenay]

I had the black death problem. I could not pull out the injector. I had a call out mechanic come to the car. He released the holding down bolts and ran the engine and got it hot and after removing the fuel connector twisted the injector and was able to release it without any pulling tool

[@SuttonCourtenay]

I then decided to remove the other three injectors returning them to the same position as each injector has been previously programmed to the ECU. I cut several lengths of cane and glued different grades of emery paper to the end and rotated them on the seat to clean them. This had been suggested in another KZbin video some 7 years ago and the car has done some 70,000 miles since without attention to the seals and a total of 218,000 on original injectors on a 2009 Ford focus estate 1500 diesel. My 2012 Ford Focus C-max 1600 diesel is having its fourth injector replaced at 62,000 miles. I read many others with this model have also had to replace the injectors at low mileage
