 working on a Mercedes. This is a main mattress, Mercedes Benz. 2016 with a 2.0 engine turbo. And I'm doing the PCV valve thinking the oil catch can air oil separator. And this is it. This part is on top and then it goes around towards the driver's side and then this is attached to the block more or less and that's the difficult bit. Guys this job sucks. Alright so up top I'm not even gonna get into it because it's simple. Just unhook every single line, three hoses, harness here and then obviously there's two clamps on each side, right? Obvious stuff. Then you just follow this hose here. There's another, I believe it's a 10mm, 8 or 10 whatever here, right on top and then you can, from the top you can still undo this hose clamp here, undo this harness and then this just kind of slides out. It's attached to this bracket. All this from the top and then it's, then it's, all you got left is just these three bolts here, okay? One here and then two on this side. And I believe this is, I don't know actually, either like this or like that. And to get to that, oh boy. So as you can see you need to raise the engine. I just used the bar. There is an eyelid on the cylinder head right here which you can use to lift the engine up or lift it from the bottom and then just suspend it on a bar and you can see it's supported just enough of this bar fully extended. I put a block over there so it's even. Gotta remove the reservoir, coolant reservoir tank, undo the harness so you can, you have more room to play around. Just kind of stick it somewhere so it's out of your way and you're gonna be down there but underneath. We'll get to the top later. Hope you're gonna see this. This is the harness you gotta get to and it's going to the right. This is the harness you unplug from that, right? Whatever you call that thing. Anyways, so you want to, you need to remove this engine mount bracket. As you can see it's loose. There's four bolts. There's semi kind of, well everything's difficult on this job but it's doable and then I could not, I had it removed right, but I could not twist it around enough for me to get it out. So I removed the actual mount which is this guy here. You can see I left it in there. Kind of stopped taking the brake from this just to show you. So now I'm gonna take this out in the bottom piece, the actual mount and then the bracket. Hopefully that's gonna come out. Here are some of the tools and bolts. So let's see. These three are from the actual mount. They go from the top down. This guy. These four are from the engine mount bracket. Go on, attach to the engine and see after taking these four out, still didn't, that bracket still didn't want to move. And there is a long, what is this, a 10mm long bolt like this that goes through the back of the AC compressor. I'm going to take this out too. Before you do any of that you got to remove this little 8mm nut that just holds on a harness or whatever. We'll see that later. And then this guy is the actual bolt that goes through the top of the bracket down into the mount. We'll see that once I take everything out. And obviously there is a biggest cover. It's right there across this whole bottom here. I forgot to mention you can, once the car is vans up, turn the wheel to the left and you're going to be able to take two of those engine mount bracket bolts off through a little gap. I'll show you where the wheel is. There's harnesses and stuff catching on the bracket. So that's what it looks like now. I'm going to leave this guy in here. I just kind of push it away. You can see how it sits and the bracket mounts there. It's got three bolts right and it just sits on top of this frame here. Something like whatever, something like that. Okay, so now it's just pushed away. Hopefully it'll be out of my way. This is the gap I'm talking about right here. Can I even see that? You're my eyes right now. I cannot see what I'm looking at. So whatever you see, not sit. Let's see this bracket. So this bracket sits like this and you can see, excuse me, sits like this just like that. The mount, it mounts on here and then this is the AC compressor bolt, that long one that you got to take out and then this will come out. So five bolts on this and there's a little guy here that just holds the harness or it holds whatever. So that's that. Okay guys, so through this gap. All right, so I can really point at the bolt but right in the middle of your screen, there is a hole. You can see the threads all shiny and just above that there is that 10mm. I believe that's a 10mm. One of them holds the air oil separator and there is the pipe right to the left of it and there is another to the left of the like two. So you see a bolt and then left of it pipe, another pipe and then you can see another bolt basically across from the other bolt and there is one on the bottom which we cannot see and now but now I know how it sits. All right, so this is what we're looking at. We're looking at this guy here maybe from this kind of view and then this pipe, this pipe and then one bolt here and then you gotta do this bolt here. Once this is loose, you gotta wiggle it out. I'm gonna assume to get this guy out. This kind of goes in. You can see this is already lubed with oil. I'm gonna put some oil here. I'm gonna put a little bit more oil here or before I put this on and stick it on but and this is gonna come out from the top. So I can't really show you what I'm doing because there's just, I can't even see what I'm doing but I'm gonna do it. I'm gonna show you how I did it or tell you how I did it. See you later. Guys, a little update like a dumbass. I tried to cut a shortcut by not taking this out, you know, but I did take the mount out and now I have a full view of the lovely separator. You can see there it is. The top two bolts, their 10mm and the bottom right bolt. Easy. All right guys, I've actually winded a bit but that's where it's gonna come out from over this AC line. Okay and I have to just lift this up. Obviously I'm gonna need two hands. Yeah, actually I could, I can just unplug this here and here and this harness will swing out and I can remove it. And there was a plug. I didn't really point to it but just behind the AC compressor, you see there's one unplugged and it's actually hanging down. Unplug that and it's still difficult. Still gotta go around this harness here. You gotta keep this up and then go under this. It's just pain in the ass. Okay, so taking the actual separator out of the, from the block, it did take a little persuading, took a long screwdriver and kind of pulled on the bottom bolt and that just pulled on it and came out and this is what came out, just a little bit of moisture. Thought maybe a little bit of oil would come out but not no oil, just a little bit of moisture. This is the old guy so I pulled on this bolt to take this out and the rest just came loose because that's just, you know, it's got a little gasket orring here so this is really the difficult part and you can see that this, whatever this may be, is no longer on the new guy. Actually took that 90 degree pipe off just to make it easier for me for now and that's, that's it. I guess I'm gonna lubricate this and this, just a tiny bit. These bolts stay there, I'm gonna come out. You can just leave them in. I'm gonna leave this too and in we go. Okay, quite a mess over here. I'm gonna stick this back in and then I'll give you an update in about seven hours. All right guys, last update before I put it all back together. So from the top, actually two tips. One for every o-ring out there, the round one that goes into the block, the one that I told you I'm gonna oil it again anyways, is I noticed once I got it all situated and I finally reached the, you know, pushing in the separator part of it, just pushing it in, you got to push it in. Don't place it on the block and tighten the bolts. It's a big no-no. You want to push it, jiggle it, whatever, do your thing, push it in by hand so you can kind of almost hear the snap, some kind of a noise that it just actually went in so that it's flush with the block. Then tighten up the bolts, never the other way around. Another tip is once I kind of shoved that separator through the harnesses and dropped to the bottom, kind of situated there, left there hanging, I went back up and started kind of making sure nothing is in the way that I put it in because, you know, remember I had to go through all these different houses and harnesses and kind of went back from the top and made sure that I did right basically. So what I did was let's move this out of the way. One side dropped it there, kind of made sure that I'm not in, you know, crossing any other houses, harnesses, whatever, that everything is going back to where it used to be but I didn't connect anything, okay? So you can see that everything I had to disconnect all these different harnesses, these just clipped in around this pipe here, like on these plastic tabs, okay? You got this plug here, this hose there, then two more on the bottom, pretty simple and then this bolts down here, it's still loose and then I'm just going to kind of start from the top again and continue putting it all back in. You can see it goes on the bottom here, under, remember this harness, the ECU harness, get over there, okay, there. Out of the way, under this guy here, this will clip in here, this was broken, wasn't me and right in the middle between the ECU and this, what is this, an AC line, drop it there, everything, the whole thing, drop it as far as you can and, you know, made sure this is all good and then went back down and actually I was able to push it in from here, kind of wrapped around my arms, you know, from underneath and just kind of jiggled it and pushed it in but that was, actually took me like 20 minutes to situate it all. So that's the, that's the hose, this guy also, there is a bracket right underneath the intake, that goes in and then you can see everything that's disconnected, more or less, and did this, this tab here, the harness, so I have more room, that's an AC compressor plug that's going to go back in and just different things, it's pretty, you know, something's in your way, take it out, okay, take a look, that's how that looks now. So now I'm going to plug it all back in on the bottom here, install these two, fix it all up on top, obviously remove all this, basically get the job done, excuse me, and I'm going to take a minute, I'm going to talk about it a little bit, torque specs for those 8 mil bolts, don't know, so I went with, you know, I'm guessing it made my big torque range, wouldn't even go in there to torque it down, but they were very lightly tight, I mean it was easy for me to get them off, so I'm guessing on 8 mil bolts, all the threads are more like for your Japanese 10 mil, but I'm guessing no more than 7 foot-pounds of torque, maybe 8, 7, 6, probably around 7, if you know, let me know down in the comments how close I was. Not that I torqued it, but you know, anyways, see you in a bit. So guys, all done, just a little recap, a few tips, I don't know if you are doing it for the first time or you're a mechanic and you just want to see what's involved and what not, but you know, a few tips, take pictures, try and do this in one day or two days maybe, so you still remember where everything goes, almost every single bolt is just difficult to get to, you've got to be an acrobat to kind of stay in a, you know, add position for a while with your hands like this and it's just, yeah, I mean my knees are killing me, that's because of my lift or my ceiling, it doesn't go high enough, anyways, when you're, for example, you're putting that engine mount bracket back on, put all the bolts in, start from the easiest one, drive it almost all the way in, don't tighten it up, then put the rest of them in, the one on top, no, the one that's on the bottom, I think it's the bottom, sorry, top left, what I do is I take a socket, I put a little, you know, something, a paper, some little paper, whatever, on the outside of the head of the bolt and just so the bolt stays in the socket, right, just a piece of rag or paper, whatever, you can even either use grease, maybe that also works, but paper is best from my experience, put a little bit of oil and threads so you can finger tighten as far as you can because then it's just a difficult time to, you know, do this for half an hour, okay, oil will help you finger tighten that one bolt or all of them, now when you're taking bolts off, start from the most difficult one, leave the, leave the easiest one last, trust me on this, so this job is asking for six hours, six hours labor time, I think I did it in like five, just over five, but it's, it's not difficult because of the, you know, complexity of the stuff, it's just hard to get to bolts, that's, that's all it is and if you don't have any information then it's super difficult then because then you're gonna know what you're doing, if you watch this, watch the whole thing, obviously I should have said that in the beginning of the video, you'll have an idea so it should be more smoother for you, all right, let's, let's see the result, I left that off because when I started putting stuff back on I noticed that this is, well this broke off for me, you can see it's been glued on before, okay and this goes into the throttle body right underneath there, so I did the right thing and, you know, fixed it for the guy, just took a, whatever this may be, a quarter inch rubber hose, oh yeah and this was Naran, this bolt was missing in my case here, so I just stuffed a hose in a hose, I guess that's a quarter inch into a half inch or five eighths, whatever and that's it, fixed and there's the nipple but actually the way it broke, the nipple I guess broke in half so and the throttle body about this much of it was left outside, likely for the guy and for me, so this is garbage now whatever, it's got to show it to the guy, that's all, all right guys that's it, if this helped you out, subscribe to this channel, like the video, comment, you know what to do, thanks for watching, see you
