MERCEDES 2009 C220 cdi stripped injector bolt. Heli coil repair. Part 1 with a case of black death 

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.

Merci beaucoup j'ai pû sauver ma voiture vous êtes un génie et vous expliquez très bien encore merci

This was a proper repair and a 10/10 video.

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.

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

Nice job Shaun. Somebody completely mullered that engine before, shame.

Love your work pal. Proper . BB

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.

MY vw passat only use 6mm bolt for injectors!! They stopped short of making it out of plastic 😀

good job nice repair ,i was surprised how many cutting turns you were doing to each back turn on the tap though ?

God job 👍

is it alright to be blowing the swarf from drilling into the head/block?

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!

Great work pal 👏, I wonder if this temporary solution still working for your customer ?

Wait a minute, did you put threads into a valve cover?

Hi Shaun. Do you need to remove the teng after it's been broken off ? If so how is it removed please

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.

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?

Same thing has happened to me in. Honda 2.2 cdti. Dont know what to do. I'm in Coventry. Can you help?

Hello, would you please tell me how long the M8 bolt is that you used for the 3the injektor??? Thank you!

just get a plug tap

bonjours quel diametre pour percer afin de mettre helicoil.merci
