Thank you for this. I have a M43 with similar problem and same style bolts. I was prepared to remove the head but I'm glad I didn't. Note: 8/10 were stripped, good luck for me lol. EDIT: I managed to repair all 8 threads!
I'll be doing this to my D series Honda engine that I'm swapping into my CRX. Looks like I'll be using an identical kit as well! Thanks for posting this video. You made it look much easier than I anticipated. I also liked that you added in some Loctite, which is something I wouldn't have thought to use.
I just discovered 2 stripped valve cover bolts on a 12 Chevy Cruze and I put gasket maker on top of both to try to hold them I place and stop oil from leaking out till I can get my hands on that tool and try to fix it for my self.
I had the No. 11 bolthole at the rear to do. Prick of a job :) Previous owner had broken the bolt off.I It was seized. Tried every strategy to remove it. Very slowly I drilled it out 3mm drill bit. Every time I thought I might have been off centre, I would down tools and walk away. Took a week. Wouldn't wish it on anyone.
I had the same thing happen to me my Chevy Cruze I was thinking that maybe because the motor was still hot and its a aluminum block but idk maybe it's just common
Question for m50b25, we have different valve cover bolts where the tread is inside the block, so I get the same kid and use a whole different valve cover bolt or get a different kit?
I didn’t have extracting tools, so I just drilled one size bigger through the hole fkn thing and put a lock nut on the bottom 😅. Safe to say, it worked out well! Haven’t removed it :))

Dude I won’t even lie I used that to screw a valve cover bolt the other day and stripped the treads I was trying to go easy too i was being lazy I should’ve done it by hand but yeah I’m not too worried about it it still threads but it doesn’t snug down all the way if it leaks I’ll do some rtv. The motor is a temporary motor while I have my other one being sent out but yeah mistakes happen
Your too strong when tightening bolts questions what's the volts on the cam sensor I got 12 pin 1 pin two 11.something and 3 is ground I think pin one of the pin would read 5 volts I have a 27bb dtc give me problems to fix engine in limp home mode have any solutions
If these are stripped....could it cause misfires? The reason I'm asking is because we had misfires on all cylinders. Replaced coil packs, spark plugs, oxygen sensors etc still was misfiring and the code that came up said a possible repair needed could be one of the intake gaskets. They said that it's possible the valve cover isnt sitting like it should..that's when we discovered at least 2 of the bolts were stripped out and it wasn't tightening down. Could that cause an oxygen issue/cause it to misfire?
@@BimmerZen thanks. Maybe this thread repair kit will be the end all of these dang misfires. I was really hoping we didn't have to get into fuel injectors, so I hope so
Thank you for putting this information out there. However NEVER use a Helicoil, you will have endless s**t with a BMW. My e90 has never been the same, either replace the block or use inserts!

I have the same problem with my e36, some how, someone didn’t use a torque wrench and stripped few thread holes.
Nicely done! Congrats

Thanks for sharing your experience. Good to know how it could be done and mentally prepare for the process:)
@@BimmerZen Mental preparation is amust!

Did you use a m7 or a m8 ?
I COULD SCREAM I JUST DID THE SAME SHIT WITH THE SAME TOOL
did your punch have a magnetic tip on it to get the tang out once you knocked it off? did not see you get it out?
what size heli coil
Did you used m7 or m8 for this operation ? please help me
M7 insert, if my memory serves me correctly

sir, I plan to repair threads on my cylinder head. my bolt diameter is 10mm. what size kit should I buy? they offer m10 and m12
As far as I know you need the M10 repair kit. Also make sure you get the correct thread pitch kit based on your bolt.
Thanks for sharing .
Perfect job! Do I need to fish out the bar of the helicoil after punching？
It's a good idea, if it's accessible.

Hopefully the bolt for your valve cover r the ones on the outside of the gasket. If not, then ya, it may leak some

Yes, you can easily have vacuum leak whee the bolts are missing and that will cause poor idle and poor engine performace

Looks like a nightmare engine bay
Great
If i have a broken bolt, do i have to rethread it? Or can i just extract it? I broke one where the valve cover goes
You can remove the broken bolt and just try and torque that position to 10 Nm. If it holds, then it should be OK.
@@BimmerZen thank you for taking the time to respond, blessings brother 🙏
V aluminij se navoje vedno dela na suho, nikoli nikakrsen WD40 ali rezalno olje
What specific loctite did you use??
I used LOCTITE 648, but any permanent heat resistant compound should work OK.
3 n 1 oil works better than WD40

Bruh u talking way to much just go through the steps already
What you talking about? He is very clear
