 Hey guys Thought I'd do another helicoil video now. I did one before I stripped Excuse me, wasn't me the bolts were already stripped when taken out a stainless steel bolt out of an aluminum body and in my case it was a brambo Subaru brambo Caliper the ears the ears of the caliper one of those stripped But and I managed to fix it with a helicoil now. What's a helicoil? This is a helicoil. You have different sizes like these guys here All right, that Total of four sizes so far. So this is a kit It consists of the actual helicoils this tool to Grab it by this little tab here and screw it in once the hole is ready This is a useless tool to knock this little tab off Which I don't use I use just pliers an actual tap which says Over here it says M8 by 1.25 but in it actually is an M10 By 1.25. That's the thread size So this thread is the actual 8 by 1 to 5 As you can see this tap is bigger. It's as big as well slightly bigger than this Drill bit that came with the kit in this nice bag by ST auto From Amazon. So this is one of those bolts that connect the intake manifold to the cylinder head and that the goes right in these holes there Actually, that's the TGV For those familiar with Subarus Anyways, these long ones go through here and these two are stripped This is a good hole As you can see it easily goes in and out all the way But these two the two in the middle Well, this one still goes in This is what I kind of want to well and now it stops I'm sure it's gonna go in can go in deeper, but it's kind of stopped in the middle But these threads are actually coming out and this is this one is just shut. That's it The way when I have noticed is how I was ready to put an intake on and I started to go You know put the bolts in and this would just stop midway and when I took this out it came out with the threads Out of the hole There you go aluminum. So that's the kit and made by one to five thread size or a Tap that's the size but in actuality. It's 10 by One to five. So if you already have a 10 you can use that tab you need to buy the kit I bought the kit for the helicoils. It's cheap. It was 15 or $16. I Bought it really for this bit. I wish I don't have and the helicoils obviously so this is the car I've been working on for I Don't know two weeks now or so waiting on parts, you know the usual Had a lot of issues vacuum leak leaks From the PCV system from the intake on the bottom of the TGV by the cylinder head which the previous mother used these spacers these kind of Separate the heads the cylinder heads and the intake manifold and And Creates a kind of a gap for heat So no get no get no heat gets transferred to the intake from the head to the intake and had a bunch of leaks I mean this this Part of the engine was covered in oil just black. It was black all this was wet from power steering leak fluid leak This hose was leaking the reservoir power steering was leaking man. I got a list. That's the intake there Where's the list? This is the list guys and this a Lot anyway, so since this is a bit more touchy. It's on the cylinder head, you know Who got to be careful? Take this off here turbo in case no, you know, no shavings get inside So I'm gonna drill these out tap them install the helicoils. Maybe double up on the helicoils That's it when we're gonna look at the result You know this car has been neglected. I'm guessing for quite some time. It's got a lot of miles 130 40 50 can remember. I Mean the intercooler wasn't even attached Just hanging in there same thing with the intake the actual filter was resting on top of these ABS lines you can see these are the paint came off the actual lines and the intake now has a hole Missing bolts here and there one of the bolts that holds the starter I actually literally took it out with my finger wasn't tight at all so I mean I Don't know I just I you know I work on these cars like that and It's scary, you know that cars like this are out there No, I should say people about the work do this kind of work are out there and just Messing these cars up any any car, you know, it was actually when I took the inner inner color off Because that Angled pipe this is actually the best mad this pipe because the diameter outside diameter of the turbo is smaller slightly By a few millimeters then the inlet of the intercooler, but this Angle pipe it's you know same size on both sides So it would not fit nicely on the intercooler, but it's as you can see it's It's too big a little bit too big. Maybe I'd say an eighth of an inch two millimeters or so by the on the turbo This guy he used electrical tape around the The turbo just hurts me, you know telling you even this story So this would stay in place, right? Okay, so when I went ahead and took it out This electrical tape actually Was covering half of the outlet. I Kid you not and as you can see it was kind of ripped apart a little bit here and there so Maybe parts of the tape is inside the intercooler now. Hopefully it never went into the engine Probably wouldn't you know like a small piece of electrical tape will probably not damage the You know any parts of the combustion chamber there similar walls and stuff like that But hopefully didn't make it there. Hopefully it's still in the intercooler. All right, so first step to drill this out I'm gonna start with The closest one to me. I need to make sure that I am straight I'm gonna drill it. I'm gonna put it in low speed. Maybe I should put in the high speed final angle Okay, I'd say it's looking pretty good There you go nice clean hole All the way down not through Just all the way down right got this little neat tool For taps there we go and This and attaches to this is by Irving Amazon Ratchet there you go if you don't have a tool like this find the right Not size Tiny bit smaller Something like this any not will work so it's got to be slightly smaller and This will actually probably work and now just knock this in This is hard steel. You're not gonna hurt this set it on a you know hard table whatever and knock it on and you can use in this case a 14 mil socket All right now another crucial step I'm using this right because I can kind of stand it up, you know Make it straight not mess it up the initial You know what I mean? I don't want it to go in an angle. This is aluminum after all so this is should be easy Okay, once in a few threads keep cutting. All right, so now You got a little issue As you can see, it's a it's a bit stuck. I don't want to force it See how it goes back in very easily Okay, there we go. So Don't force it go back in go back out in out in Never force it because if you force it You're gonna destroy that new thread And I you can use the vacuum usually what happens is if you Don't have a vacuum, you know What you do is you drive it in a little bit then drive it out Drive it in drive it out. Take it out fully Use compressed air or a vacuum. Hopefully No, but you know, you have it or even you can use oil Penetrating oil whatever any oil really so those particles will stick to the tap Take it out if you're new quarter in quarter inch of an inch in take it out Clean the tap off the particles the metals The metal will stick to the tap clean that out and go again Don't build up those metal particles inside a hole because those are gonna get wedged and Destroy that new thread Hopefully you can see what I see too much light Yeah, this camera is not very good at close-ups but we got a nice new thread Which is a 10 m10 by 125. All right, so the instructions say to Drive the coils in like that with this tab on the bottom I'm gonna do it the other way so the tab will be on the top Hopefully this works No, probably not gonna work I'm gonna find the the beginning of the thread No Not gonna work come on now Come on now get in there There we go Right So I'm gonna try something here Not gonna remove that tab on the bottom just yet I'm gonna see if I can double up on the on the coils. All right, just came back from dinner What the hell was I doing? Oh, yeah so I Have maybe a thread and a half left Now notice I cannot Drive this out. It's in there once you get it in there You basically have to destroy it to get that heli coil out so as of Now I mean there is a tiny bit deeper now. It's not flush With the head, but this will work. So what I'm gonna do now. I'm gonna take a second heli coil and See if I can fit it. Well, I'm sure I'll be able to Okay, did come out try this again the plan is to See if I can with both in There is a little bit of space in between the two if I can actually drive in the bolt through the Two coils where they meet. I think I have to drive it in all the way. So they actually touch Oh, yeah, I have to remove that tab Which I forgot so Okay Going in There you go. That's it. I can actually see it. That's all the way in. I'm gonna take small pliers These actually will not reach In there these won't either. All right, let's see if these tweezers will do the trick Basically, I just need to break that last piece off, but I need to make the transition from the top coil to the bottom as Smooth as possible. This is just too flimsy. All right, I'm gonna use this useless tool. See the instructions actually say just to push it down Push down until you break the tab. Obviously, that's not working. You can just use this tool to kind of Go back and forth on it. What to do? What to do? All right, let's see if I can just push the Tip of that tab with this pick tool do something with it. Come on break off already I don't think this is gonna work guys because it doesn't want to have a clean break Okay, I think I got it No, still there. Why don't you want to break off? So there's even a little cut Right here first. So the idea is to you know when you push this down From the inside This is supposed to just break But it's not There we go No still in there. They didn't they didn't vacuum it out. And now I have a space like a tiny amount of thread missing Because they're not touching each other. Now I need to drive it in Actually, I'm gonna try the the bolt See what happens. Yeah, I'd say it went through Both coils easy. There you go. So that's why I wanted to use The two coils now there are longer coils But I couldn't just find a you know a set or a pack of Those longer coils. I don't want to be waiting on this for weeks or whatever I can still reach the bottom coil Drive it in more Because that tab is still attached to it. I think that's all the way in now. I should be able to Screw this one in a bit more Check this out I'm gonna cut the excess off Man, this is hard steel. It goes way past the black mark Well, maybe one thread comes out easy. So second time much easier So all right that that was just I was just trying to See if it's even possible to fit two coils in one hole. I'm gonna do the other the other one Maybe I can come up with a different way of doing it easier faster because I realized this was kind of long and you know time-consuming and And boring To watch at least but you know you learn something so if I'm gonna come up with a new idea I'm gonna give you an update after guys the second one Took no longer than eight minutes. I should have showed you the clock before and after but Second time obviously things take take less time there you go All the way in and it comes out. It's a little bit harder once you go in a bit deeper, but that's okay Nothing a ratchet won't take care of you know I think I have all the parts to actually install this intake manifold So I'm gonna drop it in make sure all the bolts go in and I'm gonna show you the result these tore down to 18.1 and And that's it. Voila. No need to panic get yourself a heli coil. They do work great. All right guys, so I guess this was just a Video to show you that you can use and I wondered myself if you can use Two heli coils in one hole and service. Yes, you can. Thanks for watching. See you soon
