Hi Mark I think the pnumatic injector removal tool would work a lot better with a bigger ID air line and possibly a bigger compressor if you are using a small one ,great videos by the way ,showing it all warts and all
Thanks for posting this video, I was having a nightmare trying to get this loose, I was looking at forums and they were talking about cutting the pipe and adding something on which I really didn't think was necessary, came across this video and it worked so thanks for that 👍
On my traffic, I had to take the head off, pour diesel and atf down the injector hole from the injector tip , left it overnight then knocked it out and that was after trying alsorts of pullers, slide hangers, impact gun, air tools.
The best way I remove stuck injectors is to remove nut holding injector, pour red diesel over injector, drive until it breaks loose. The heat and compression will loosen it. Easy and simple
Instead of drilling the engine, could you of got some,10 mm bolts and just turned the end down and re thread to 8mm, so bolt 10 mm at top were water gets in and 8 mm at the bottom. Even put the bolt on a lathe and cut a recess the 10 mm side to take an O ring.
Hi That's a good idea, mate 👍 the top where the head is , is 10mm it was good for a guide when I was drilling it out , but a could still cut a Grove in these m10 to take a thicker O ring 👍👍
I've one of them aswell to did nothing but make a noise 🤣 , Worked on one of my other videos on that other engine. Think on normal injector it would well 👍
@tinker-time ah cool, perhaps liquid moly injector remover and the tool again ? Cola works but the moly should be more concentrated phosphate to convert the rust
I bought some clamps off of Ebay, They are usually made in high tensile steel, and if you are lucky, flat. I used to machine large items on 10 foot table vertical borers, so big clamps and bolts with ten foot spanners was normal to stop items flying off the machine.
Couldn't be ar5ed with all that pulling - waste of effort. See this nonsense endlessy - 40 ton of pull is nuts - apply twist. Never pulled on an injector in my life - I slam them sideways so they shear the carbon bond. Twisting is your Pal for injectors. Think it through - it's a long round bar jammed in a long round hole - it can withstand huge amounts of pull - but sod all twist. Once the "Twist don't pull" idea sinks in, you never give much fecks about how "Stuck" an injector is - it's not really. If they resist the twist, I hit them around with the air-hammer - they all give up.
@@tinker-time Cobblers - they all twist free. I see lads here in our workshop struggling - pulling, heating, welding, all the usual rubbish - I wander over, smack them sideways with a big heavy punch & a big heavy hammer - bingo. Issue is they're frozen in place by a layer of carbon. That carbon is strong as glass, but also brittle as glass. Break that bond & out they come like lambs. It's identical to "Can't be undone!" bolts.. One guy can struggle for hours, another will have it out in seconds. The second guy will hit it so hard with a hammer, first, it will forget any & all ideas it had about being stuck. You need 0.5mm of sideways movement - that shatters the bond. Every injector going moves that 0.5mm. Pulling is not your Pal.
@@tinker-time I do these daily - hit them around clockwise. Grab a big heavy punch - heavier the better & a big hammer. Smack the offset around clockwise - you only need it to twist a tiny bit. The bond is real brittle - but it will resist 20 ton of pull no bother. If they pi55 me off and won't twist (rare), I hammer them down into the copper washer, then hammer them round - out they come. That means I have to spend 50 quid on a used injector, so I try avoid that - I prefer getting them out intact. Idea is to break the bond - I'm lazy & overworked, so I try avoid marathon sessions dicking about with stuff.
I've gotten seized Injectors out of an LDV Maxus engine using cokeacola, pored it around the Injectors, and left it to eat away and work its magic before removing them
It wasn't easy, but a bit of persistence over a few days, and I got them out, all damaged, of course, on the LDV engine, the head can't be removed until the Injectors are out, so couldn't even remove the head. Good luck
I use 60mm thick milling clamps off of a large vertical borer. They will take 100 tons and not bend. At least you tried, how do you get them back in if they are that tight?
Had this malady recently with an I40 Hyundai. One injector stuck, would not budge. Had to drop the head off to a engine specialist, and they pulled what was left of the injector. The renault R9M engine you have there is simple to time back once the fixed head is returned; you've done half the job already having that lump out to give yourself room o understand what causes this is a blocked scuttle drain; rainwater sits on the top of the engjne and works its way into the injector recesses and fuses the head and injectors together as one. If you remove the head and send it off spend a little more and get it skimmed, as these heads are susceptible to overheating and warping. Just future proof the motor as much as you can mate. Also if you have the injectors out, keep them in the order they came out, and recode any you replace
@@Everydoghasitsday259 It was the same with the hyundai in that the injectors go through the rocker cover. That had to be cut up to remove it to expose the rocker gear and cams which had to be removed to access the head on the hyundai.To be honest, this is the only cost effective way is to sort this himself, or otherwise splash out on a warrantied reconditioned engine. The engines only problem is the shithouse injector. The cost of the rocker cover, head gasket set, injector to replace the scrapped one, injector removal and skim by a specialist. It's alot, but less than replacing the engine with one that'll have the same issue come the time all over again, plus the added for the replacement injector. These are renowned for this issue in this van. At least, on reassembly, after recutting the injector seats, the next step would be to paint a smear of copper grease to the injectors to five them a fighting chance of not seeing in again. Other thing is to make sure the scuttle is draining properly.
@@Everydoghasitsday259 Unfortunately I had to so one of those too but it was a warped head which is common on these renault engines, luckily not an injector on that particular engine. However the seizure issue is common on these due to that one cause. Its just another typical annoying modern design oversight that's too common. At least the renault engine only has the one simple timing chain to be bothered about. Its a doddle to time unlike the hynudai 1.7crdi engine. It uses a chain from the crank that times the fuel pump, then a second chain which times from the fuel pump to the cams, plus the oil pump is part of the timing case, silly engine!
How about putting some pulling pressure on it, then rattling the injector with an SDS hammer drill or something. The impact vibrations might break the rusty corrosion weld effect.
Take the head off and push it out from other side.Look how a bearing press is made and make one using the 40 ton jack, and use "I beams" , welded and bolted, Heat the hard up before pushing.. and use plus gas.. If that dont come out then get another hear and injector.
dont know what the access is like to the injector, but have you tried wrapping an induction heater around the injector, have seen good results. those air impact injector removers are also cheap on ebay now.
These videos are becoming the highlight of my week 😅, I've never seen such stubborn injectors lol, I hope my ones on my 2.0 vivaro never get this bad lol.
Cheers, mate. 👍 A someone has gotten in touch with me, so I've afew ideas, so I'm sure I'll be having another go. I think more safety gear is needed. 1st tho🤣
Just watched this latest attempt Mark…😳. Did you ever work in Bomb Disposal? You should do..😂. Well done for another heroic effort. Yours is one of the most entertaining channels on RU-vid!
Scary thing is I have a 2011 lwb tvp and know the days coming I'll need an injector or two, but that sir is a new boat anchor, it's all its good for with injectors that stuck. 10 out 10 for effort though 👍.
