- Vehicle brought into me for popped injector...Common fault on these engines as the original stretch bolt often breaks off in the head... Having cleaned the black death carbon from the top we find all four injectors had been repaired previously...I believe this was done as a bodge to sell the car on quickly. Within weeks of buying the car my customer was suffering with these injector issues... No2 is the injector that popped out. This is the one we repair with a helicoil. Part 2 will be a short video showing the result after No1 n 3 have been done
Very impressed with the work you have done there 👍 there’s a lot of shops that wouldn’t have taken the job on any many would have said the head is scrap.
Thanks for watching and your comment.. I have told the customer that this is a temporary repair at best and idealy it does need another head... but as he said we had nothing to lose trying to fix it.
The head is not a scrap, but a workshop had to provide you a warranty I guess.
If you don't need warranty and ready to pay twice for next repair (head replacement) why not to make the same job
Merci beaucoup j'ai pû sauver ma voiture vous êtes un génie et vous expliquez très bien encore merci
got some good info from your video. my heli coil was on the top flushed and for some reason, it wouldn't screw down...it got tight in a few turns...time to drill out the heli coil and redo it. thanks
This was a proper repair and a 10/10 video.
Appreciate you watching and your comment.. thanks
Appreciate you doing this, I’m doing this on a sprinter truck, I’ve followed the same method but I snapped the clamp, I must of tightened it too much, I come back to your video and realised you only tightend till it felt tight which makes sense as it’s a much bigger bolt.
Hi. I’ve had to do this to my w204. You don’t have to drill the head. The hole is big enough for 10mm tap to fit a 10mm bolt or you can put a 8mm helicoil in it for a 8mm bolt.
I have a leak from #2 cylinder injector bolt bottom, seems there is a metal ball missing in the bottom where the threads are. When blowing air into the hole, coolant gushes out. The 3 remaining holes have the metal ball on the bottom. Used a bore scope for inspection.
Love your work pal. Proper . BB
Thanks for watching and your comment
عمل رائع
is it alright to be blowing the swarf from drilling into the head/block?
Nice job Shaun. Somebody completely mullered that engine before, shame.
Thanks for watching and your comment
Wait a minute, did you put threads into a valve cover?
good job nice repair ,i was surprised how many cutting turns you were doing to each back turn on the tap though ?
Hi Shaun. Do you need to remove the teng after it's been broken off ? If so how is it removed please
@@AlanHunt73 hi, yes it's best if you remove it. Best to blow it out with an air nozzle thats what i usualy do... I suppose you could pick it with a magnetic screwdriver or simular tool.
Thanks for watching and your comment
@@shaunsautorepairs5410 great thanks Shaun.
Shaun would using loctite on the helicoil be ok. I know it's not needed but I want to make sure it's solid
@@AlanHunt73 some say yes, some say no. I dont think it would add any additional strength to the Hele coil. I can't realy advise one way or the other
@@shaunsautorepairs5410 thanks for your time mate
MY vw passat only use 6mm bolt for injectors!! They stopped short of making it out of plastic 😀
Great job, I have a 2002ML 2.7 diesel and have noticed that injector no.3 has blow by and previously repaired by someone using what looks like a 10mm bolt. Do I need to purchase a stretch bolt of the same size when I do the job or can I just use the old bolt being that its not to spec?
I have an ML270 and had an injector blow out although it only stripped the thread from the aluminium head. I have used an M8 heli-coil insert with a shorter bolt exactly as used in this video. I used a 24mm long insert and a stainless steel cap headed bolt as there is no room for a normal bolt. I have drilled out the injector clamp to give clearance for the 8mm bolt and it has lasted 64,000 miles so far. I am lucky in the respect of, if I screwed up, I did have a spare cylinder head.
@@jsapsed7022 did you torque it?
Yes, if I remember right, it's 6 or 7 nM plus 90 degrees and maybe 90 degrees again. Not very tight. @@cali_cal
Can I use 10mm on a om646? I'm wondering if there is enough space and that I don't damage something like a cooler line.
Hi, I couldn't say for sure as I don't know the engine specs but if the original bolt has snapped off and drilling is the only option I would say maybe an 8mm is a better choice. The larger diameter means drilling more out the clamp weakening it..what ever bolt you use just drill deep enough for the bolt to seat properly. Sorry I can't be more help. But thanks for watching and your comment.
Same thing has happened to me in. Honda 2.2 cdti. Dont know what to do. I'm in Coventry. Can you help?
What a pain. Is this something your looking to repair yourself or are you putting it in the hands of a local garage?
Hello, would you please tell me how long the M8 bolt is that you used for the 3the injektor??? Thank you!
It was about 35 - 40mm as I recall I didn't think to measure them
@@shaunsautorepairs5410 Thank you very much!! Have a nice weekend. Regards Paul
God job 👍
Great work pal 👏, I wonder if this temporary solution still working for your customer ?
Febuary 2023... its still going
July 2023.... still going
a garage down the road from me is having to do that same job on my 2006 Vito. I expected it to be the seal but same problem... needed that big job youve done. . doing it Friday morning. it's gonna cost me £400 is that a good price do you think? or too expensive. I don't know. it's only injector number 2. but now I've seen your video . I really hope he doesnt ring me to tell me they are all gone.
.At the end of your video when the other ones had gone. I had a similar reaction. almost as if I was there. like Oh No!!! brilliant video anyway! keep up the Great work!
Hope your turned out OK... I did 3 out the 4 and I charged him about £200 but I don't have large overheads and hourly charges like most garages who have to account for every hr of the day.
شكرا على الفيديو
bonjours quel diametre pour percer afin de mettre helicoil.merci
0,3 au dessus de la taille , d orrigine c est du m6 donc perçage en 6,3 pour remettre un helicoil afin de reutiliser une vis d orrigine , sinon perçage pour du m8 en 8,3
@@adrenalinbulls4169 merci

Bonjour j’avais le même problème de l’injecteur j’ai les réparer 270 euro 😉 chez Delestrez
just get a plug tap
Night mare
Hi, how long ist the orginal bold? M6? Thanks
Hi, I haven't got one to measure but I'd say it's about 85-90mm long. A long thin bolt which is why they tend to snap off.
Thanks for watching and your question.
@@shaunsautorepairs5410 i think 85 cm. Thanks
