This was educational for me, I have never personally seen anyone with the tools or ability and patience to achieve what you have done here. It's also a great example for anyone that needs to see just how hard they are to remove. Cheers mate

[@davesterl]

Thanks Matt for your kind words

[@blackbirdmark495]

Excellent & very informative video, i’m just glad that I didn’t have the same battle in getting my volvo d5 injectors out. Keep up the good work 👍

[@kennedysgarage3281]

😂😂😂 Fair play Dave, that was a challenge. Apologies for not having time to see the video for a few days ☹️ This engine was outside in the rain for around 12 months Dave & we had 2 injectors that failed. We tried to remove them but we didn’t have the determination or skill that you showed here. Other than that the engine was good. All very good pointers & tips on how to get out extremely stuck injectors though. I was on the edge of my seat & jumped when the weld’s snapped 😬😬 Thanks for taking the time to record it 🙏🙏

[@claudiomacierzynski2305]

Excelente demostracion , me ocurrio con un injector de Mercedez Sprinter cdi, la gente no tiene idea lo problematico que es cuando un inyector se atasca de esta manera. Muy buena demostracion ! Felicitaciones por el video! Me encanto! Saludos desde argentina!

Great bit of experimenting Dave, helps us all out. Thanks!

No bother Simon

great job dave that was a good watch you want patience of a saint on that one

[@Jonodrew1286]

👍👍Excellent work and perseverance - they are a pain the extract in the vehicle - drilling them out takes an age - I bet all the clamp bolts were broken inside - The piezo one’s are not as bad as the solenoid ones - same beast different attitude - 🙏🙏🙏👍👌👌👌😅

[@dreddwailing5505]

The most annoying thing is that if you really wanted that injector to stay put it would fall out

[@ojmbvids]

When adding more mass to the pneumatic slide hammer, I think you'd need to add it to the moving portion to give it more impact on the travel stops. By adding it to the injector, I don't imagine it would help at all - if not, somewhat hinder it by trying move more mass with the same amount of kinetic energy from the hammer.

[@davesterl]

Ok maybe i should have explained 'adding mass where i can add mass'

[@TheGibby3340]

Impressive determination and patience Dave. Wee bit scary with those kinda forces at play. All good experience for the brain bank 👍

[@davesterl]

Dunno about the patience but certainly determined. I wanted to find what would work and where the failure points are. Time well wasted

[@TheGibby3340]

@@davesterl Well wasted 😃

[@GRUSSNewton]

Hi Dave very interesting video! When I used to change injectors under warranty at Vauxhall a chap from vx technical in Newcastle told me his technique and it never failed on me. Number 4 was always a pig to remove like you’ve mentioned. I used the dealer tool, a tin of freeze and release spray and a air chisel…. Infact my first video on my channel is me removing one 😂 Keep up the good work!

[@davesterl]

Yrah Gruss these were well stuck and all broke. Yes, the freeze spray seemed to help. Heat or fluids had no effect. Do you think a running van would be easier as I'm thinkong this one being outside didn't help. Also were you just attached to the fuel pipe connection? Cheers

[@GRUSSNewton]

@@davesterl I was working on no more than 3 year old vans so was very lucky. Yeah the factory tool just screwed onto the fuel pipe connection. Like you said.. more for you really 👍

Very interesting. You’d have thought Renault would have perfected the window scuttle by now! That’s as bad as Nissan Leaf front strut mounts filling with water!

[@shadowBanned2023]

Is there any upward pulling force on the nematic hammer? Maybe if the engine was upside down

[@melindabahmed9217]

hello dave great video could you give me the link to buy the hydraulic tool that took out half of your injectors and I would like to know if it fits on other model thank you

[@oldgit1091]

The sleeve comes out with the injector and good luck you will need a 10 or 20 ton hydrologic puller BIN there and changed mine after hours of work

[@davesterl]

really? i thought i had a 20 ton hydraulic ram on these injectors in the video

[@PaulysAuto]

This video is absolutely therapeutic, I highly recommend for all those with OCD 🤣❤️🙏😇 By the way, the wife wants to know can she have your pneumatic slide hammer...she said she likes the vibrations mate 🤣🤣🤣🤣

[@davesterl]

Woah, steady on there Nathan. Lol

[@PaulysAuto]

Too funny we were watching your videos today...🤣👍

[@ShulamitHanegbi]

My ocd really wanted to see those nozzles removed after the head was lifted. Now I won't be able to sleep properly 😢

[@DJ-tn7vj]

Hi Dave. Next time use old brake fluid as your lube. It creeps down into the injectors and the heat will wake it up. Glad i didn't buy that pneumatic tools, it probably works well but i saw many stuck injectors before. Old brake fluid works

[@davesterl]

Do you think the addition of brake fluid would have got these out? The pneumatic slide hammer is a great tool.

[@DJ-tn7vj]

@@davesterl the hammer is a solid tool. Was going after it but wasn't able to get it from the supplier prior to guys using it now. But i learned that trick a while back with brake fluid and how it works to get corroded things apart. Try it and let me know how it goes.

[@davesterl]

@@DJ-tn7vj do you think the addition of brake fluid would have got these injectors out?

[@DJ-tn7vj]

@@davesterl yeah. I stopped throwing away old brake fluid a while back. I use it to remove stuck axles, bolts and so on. Neat trick.

[@davesterl]

@@DJ-tn7vj No fluid would help getting these injectors out as the sleeve is sealed to the head with corrosion. No fluid can get in. Your method may assist in moderate cases but this is a deliberately selected extreme case.

[@brucemoxon7383]

Hi Dave thoroughly enjoyed your video, I wonder if you had heated the engine up by dropping the whole lump into a tank of boiling water , then using the freeze locally on the injectors would have helped with the coefficient of expansion being greater for aluminium or perhaps in an oven ? . as i watched i was thinking , ill bet he welds something to them , great job , I dont like to be beaten either

[@darranmorrison2176]

Great vid Dave - Thank you.. If you were replacing the injectors... Obviously, stopping the dripping water on to the head maybe enough so the new injectors dont seize in.. Would you add an anti-sieze type compound to the new injectors as a precaution?? Thanks in advance

[@andyvan5692]

at 9:49, the right idea, as it is in a sleeve, but use a butane or oxy torch, on the HOUSING, and then some "freeze and release" on the injector, this will cause shrinkage, hence break the hold the rust has on it.

[@davesterl]

On the HOUSING

[@andyvan5692]

@@davesterl YES, right by the sleeve, as if you heat the injector, it will expand, and get more stuck in there!!

[@davesterl]

@@andyvan5692 you do know it's aluminum

[@andyvan5692]

@@davesterl No I didn't, as for diesels, thought most of them where steel, or cast iron, esp. the block parts (pressure in the combustion chamber is higher, so was a logical assumption), but Dugh!-thanks for reminding me, of course that's why the tools are a set of guided drills and reamers, to tap and pull, or to mill out the offending parts!

I’m surprised that none of the glow plugs snapped

I tought freezing might be better as causing that the metal are going smaller in size hesting expand the metal in size

a scrap engine over the injectors . that sound like some sort of challenge

[@wheater5]

All for the lack of a smear of anti-seize at the factory.

[@leekirtley7234]

The big plate one wasn't pulling square and that's why it snapped😢

[@davesterl]

might have appeared so on video

[@SGTECH-di9df]

Holy hell apparently I've been dealing with easy injectors compared to this! I wasn't even aware there was a pnematic slide hammer and never considered using that hydraulic tool to pull an injector I've only ever used it for bushings and bearings. Bravo man, I couldn't stop watching. What pnematic slide hammer do you have?

[@captainchaos3053]

Anyone ever tried taking the clamps off and starting the engine? I did it once on an old Peugeot. Never found the injector. Its poor design you can't just change the head rather than scrap the motor?

[@NobbyonDaNET]

Hi Dave, great video thanks for show us how difficult it is. I’m thinking of purchasing from eBay the hydraulic puller, but also like the idea of pneumatic slide hammer not just for the M9R injectors. What is your input?
