With now four Mercedes with the M112 and M113 engines (CLK 320, ML 320, ML 350, ML 55), I keep coming back to this video whenever I pick a new one up and need to do gaskets. You have by far the best guides for them. Thanks!

[@L35inColorado]

Wow, thanks! You have quite an MB fleet, and that's great that they're all the M112/M113 engines. Please be sure to leave any of your tips! Thanks for watching and for keeping those MB's on the road : )

[@angerthosenear_yt]

@@L35inColorado Thanks! I actually have a few more that aren't M112/3. '76 450SL, '83 300SD, '93 190E. Slowly getting a different letter class from every decade. But I like the diesel OM617 and these M112/3 the most. As for the M112/3 engines I haven't had much issue with them. Just the usual things like valve cover gaskets and power steering getting leaking and whiny. I've been through one transmission on a high mileage ML350 (254k) that from what I can tell was never serviced. The new transmission adapter plug is pretty critical to replace by this age and mileage they tend to have. I've also used the Salvox valve body sleeve kit and the Transgo kits with some success. I did splurge and get the STAR setup for scanning, which helped with some of the BAS/ESP systems.

[@L35inColorado]

Outstanding - great job on your DIY! Thanks for your comment, and thanks for watching : )

[@coinwaters]

Amazing. It was as if you were working beside me! Hoses snapped. I hit the brake booster cable while reaching MAF air intake clip (I see you have the red junction on yours so I assume that you broke it earlier). Was so proud I got that throttle body off cleanly until I was trying to get the old hoses off and snapped that small tube off in my hand. Another two day delay. All part of the journey. 😂 I cannot thank you enough.

[@L35inColorado]

Yes, these MB hoses and connectors are so brittle! MB should just buy those parts from Toyota already, haha. Thanks for watching, and I'm so glad the video was helpful! : )

Your use of plastic baggy to catch the fuel was genius. I was thinking about small cup or bowl. I saw another video use a towel. I decided on a 1 gallon ziplock baggy and caught every drop!

Revisiting this video because I finally replaced my ignition coil locking connector clips on my w211 e55 Amg & installed NPboosted ignition coils . You gave me the idea while watching this video for my some maintenance I wanted to do on my w163 ML500 . I purchased 8 connectors on eBay $30 total . They are genuine Mercedes clips but I typed in sprinter van to get better prices because they can get pricey for a single clip if it you don’t shop around . As long as the part number is the same that’s all that matters . so THANKS for your detailed videos full on information!

Great tutorial. This was by far the most DETAILED and well laid out video out there regarding this job. Really hope to keep seeing more W163 content on this channel as time goes on. You deserve more subs and views! Especially for someone who has never done any major work on their car before, this video clearly explains everything and makes this type of job a lot more approachable with your careful explanations. A lot of the DIY videos online tend to skip over many of the basic things that maybe an experienced DIY home mechanic might already know but for a complete car noob like myself will 100% miss. Also was a huge help with all the screw sizes & part #'s so I can prepare everything prior and order things that I will most likely end up breaking lol. Thank you again!

@@L35inColorado Do you have a link to the torque wrench you used in the video? Been trying to look for it

[@L35inColorado]

​@@lv352 Yes -- The 3/8" drive compact torque wrench shown at 43:29 is the Icon 56614: www.harborfreight.com/38-in-40-200-in-lb-professional-compact-torque-wrench-56614.html The little 1/4" drive torque wrench shown at 42:26 is the Tekton TRQ21101: www.tekton.com/1-4-inch-drive-dual-direction-click-torque-wrench-trq21101 The Icon is excellent -- I wish I would have bought it years ago (I didn't because it is expensive, but then I got a deal, so I bought it -- it is worth the store price even). For years I used the Pittsburgh 1/4" drive torque wrench (www.harborfreight.com/14-in-drive-click-type-torque-wrench-63881.html) to cover that approximate torque range, and that inexpensive Pittsburgh works just fine, long as you use it correctly. But the Icon is so far superior to other torque wrenches for that range that I just really like it, and that's the only torque wrench I use now for that inch-lbs range! I love that Icon. The litlte Tekton is also nice for very tight spaces or for very low inch-lbs applications, but it doesn't get as much use as that Icon, though it is a good little torque wrench. I hope that helps!

[@nme700]

Thank you for making this video! This is an excellent video! This is probably the reference standard for gasket replacements on M112/M113 engines. Great job! Wish I had this as a reference before I did valve cover gasket twice. Once with aftermarket gaskets and another time with factory Mercedes gaskets. The aftermarket gaskets leaked within a month. The factory gasket is not leaking (it's been a year already) but the gasket is a bit wet around the half circle areas you mentioned in the video. Hasn't developed into a drip but if I ever do this job again, I may put a drop of rtv in those corners.

[@L35inColorado]

Thanks! There are a few other very good videos on this job on youtube; I just wanted to make a more complete video for those who haven't done it before, because this is a great DIY but can be a little intimidating for those new to auto repair. I agree about the MB gaskets: they are more expensive (basically twice the price), but they fit so well! Some say that VictorReinz makes them, but I can't confirm that, and I compared a VictorReinz gasket to the MB gasket and there was no contest -- the MB gasket was simply better. And yes, I also debated about the RTV at the half-moons, and I decided to go without it: the main reason was because when I removed the gaskets on the V8 (which were MB gaskets too), they weren't leaking at that spot. So seeing as the new gaskets fit so well, I decided not to use the RTV there. But I don't think it is a bad idea to use a little RTV there, and I know that many have used it with success. Thanks for your comment! Since you've done this job before, please leave any tips you'd like to add for others, and I can add them to the Pinned Comment. : )

Great video. I have a 2005 C240. Real pain to get access to those breather hoses because of the tight spots around the air distribution connector. The map sensor assembly is blocking access to the air distribution connector when the brittle hoses joint together . The MB dealer in Santa Monica charger 225 hour for labor only so about $1800. Not including parts. The labor for MB vehicle repair is very labor intense.

[@L35inColorado]

Oh wow, that's interesting - yes, it can really slow down the repair process when there are other components in the way, like you're describing. I hope everything goes well for your repair. Thanks for watching, and for sharing your knowledge about the '05 C240!

[@cacopapote]

I just bought one of these with the M113 engine. What socket, extension kits, etc do you recommend for an ML first timer? I do work on older european cars, but I don't have a single E series socket for example. Thank you for the fantastic video BTW!

[@L35inColorado]

Congrats! Mechanically, these ML's aren't difficult to work on, but the electronics can be a bit of a headache. As far as tools - you'll just need the normal set of ratchets, extensions, metric sockets, etc, for working on cars in general, and then as you mentioned, you'll need some E/external torx and T/internal torx sockets. I have a couple sets of E sockets, and these are my favorite - especially for the price! www.amazon.com/gp/product/B07JFJD53J You'll also need the more common "star" or T/torx sockets, because those fasteners pop up all over the engine and body, such as here: kzbin.info/www/bejne/m6qrqp-bhMuXgrM You'll want at least a basic Torx internal and external sets. I don't have this particular set, but for the price it's got a lot of sockets you'd use on an M112/M113: www.amazon.com/MIXPOWER-External-Professional-Motorcycle-Mechanic/dp/B08ZJ56Z9W There's a specialized wrench for the plug wires, if you plan on doing that job - it is not necessary, but makes the job a lot easier (since there's 16 plugs on the M113!): www.amazon.com/EWK-Remover-Installer-Wrench-Mercedes/dp/B00H95I5EM/ Like any engine, there are those little things that pop up where you'll find yourself having to buy a new tool. I do recommend always using a torque wrench on these engines, too, because they are made of alloys that can be unforgiving if something is over-torqued! I hope that helps - have fun with your new ML!

Hi thank you. Do you have an idea where i can find a list of recommended tools needed for this job?

[@L35inColorado]

All the tools used are shown in the video; as far as I remember, the specialized tools are the E-sockets (external torx), which are commonly required for MB repairs. If you don't have such as set, I can recommend these: www.amazon.com/gp/product/B07JFJD53J Other than those, the tools are general automotive/DIY tools such as ratchets, extensions, etc. I also highly recommend to use a torque wrench, if possible. I hope that helps - good luck! : )

[@rsulka]

I would have tried a screw extractor to pull the tube...may or may not work. Grinder to make stepped pulling tool also. I have done things like put a screw in the tube such that the head catches underneath like the pick tools.....then wedge in a stick carved to hold the screw head tight to one side so it can't slip out.....then pull the screw and tube and stick all out. I have manually moved throttle valves without damage, but I don't like it. There's a stepper motor on it and you can feel it moving. I usually move them some to clean them. I have also forced and held them wide open and put the shop vac on the intake as a blower to push air into engine.....turn engine until air is coming out the sparkplug hole you need to chase or time-sert and this way you can minimize chips left in cylinder (BMW M5) but the chips end up on you.

THANKS SO MUCH. I took the head off on the driver side and didn't see it . So it must be resting on the timing chain near the bottom of the engine block. I will try your suggestions and get a vacuum cleaner with a skinny hose for sucking oil out of the engine. Maybe with a camera i might be able to know at least where to point the hose on the vacuum cleaner. Do you have your shop in LA? If so, let me know and i will be one of your best customers.

[@L35inColorado]

There are boroscope cameras on Amazon for even as low as $20 or so, and yes I agree that a boroscope would be very helpful. If you have a shop vac, you can use a reducer kit like this, or as I mentioned just slip one hose inside another until its small enough: www.amazon.com/Shop-Vac-906-87-00-Universal-Tool-Adapter/dp/B00004RHKU I'll say a prayer that you find that screw! Good luck! : )

[@Carl-eu6ns]

So is there a way to just reseal the breather cover and not mess with the valve cover? I'm guessing it would be too hard to clean the surface of the valve cover where the breather cover gets RTVd on. Your videos are priceless! Thanks.

[@joc.9082]

Thank you for this. A mechanic changed both my gaskets and now there's a check engine light and a burning smell. Do you know why this might be happening?

[@L35inColorado]

Wow, I'm sorry that's happening - if you don't have a scanner, you can have the Check Engine light code read for free at most auto parts stores such as Autozone, O'Reillys, Advance, Carquest, etc (if you don't want to return to the mechanic and have them read it first). If the Check Engine light came on right after the repair, my first guess would be that they forgot to re-connect one of the many hoses that they would have needed to disconnect to complete the repair. If that's the case, they will be able to tell with the code because it would show a vacuum leak somewhere. As for the burning smell: the best case scenario that I think of is that often doing this repair, oil drips onto the exhaust manifold. Once the manifold heats up, the oil burns and there's a burning oil smell - but that should go away fairly quickly unless there was lots and lots of oil that leaked there and wasn't cleaned up. There are other things, though, that aren't so simple that could cause a burning smell, so you want to get that checked out. In summary, I would probably have the code read at Autozone, etc, and write down the code or take a picture with your cellphone. Don't have Autozone clear the code - just have them read it. Then I'd return to the shop and ask them to review their repair. Hopefully it's an easy fix! I hope that helps : ) Good luck!

[@joc.9082]

@L35 in Colorado thank you very much for your feedback. I will bring it in to be scanned. Drove it around the block and it stalled and started sputtering. Thankfully, I am not far from an autozone or mechanic.

Yes, on the driver's side, you do need to disconnect the fuel line because it is right in the way for removing/replacing the cover -- but as you can see, it is very simple to disconnect the fuel line!

Hi do you have to number the coil packs? Thank you for the video

[@L35inColorado]

You certainly can number the coil packs if you remove them altogether and that keeps you organized, but if you're keeping them connected to the spark plugs (as I am doing in the video), then it is apparent how they fit back onto the valve cover because you're just removing the mounting screw, and they will only reach to their proper spots. I hope that helps : )

[@MarioMaresSr]

Thanks for the reply. Are the six coil packs the same? Reson I ask because I removed but did not numbered them. I assume the coil packs are the same

[@L35inColorado]

@@MarioMaresSr Yes, they are the same - in fact, one way of troubleshooting misfires is to swap a coil pack from one cylinder to another to see if the misfire is due to the spark plugs or due to the coil pack.

I need your opinion: How do I remove the aluminum screw that I dropped into the engine while removing the breather cover on the driver side of a 2005, C240 benz? Is there a led camera i could use?, a strong oil vacuum pump to suck out the aluminum screw. Appreciate your time.

[@L35inColorado]

Oh no, I'm so sorry that happened to you! Here's what I would try first: - Reduce the sucking end of a Shop Vac hose to a smaller diameter, for example small enough that you can get a 5/8" or 1/4" ID hose on the end, so that you can get the hose into small areas and also so that it will be the effect of having more suction; - You can reduce the vac hose by buying short sections of automotive hose at an autoparts store, then slipping the smaller hose into the larger hose until you have it reduced, etc, or you can buy a reducer and end slip a small hose at the end; - Use the vacuum to suck out as much oil from the valve train area as possible to be sure that the screw didn't just fall into the head/cams area - maybe you'll get lucky! If you're certain that the screw did indeed fall down into the engine from an oil galley hole in the head, or if it fell into the timing chain area, then: - I would use a boroscope cam to look into the timing chain area and try to see the screw; - if that's not helping, then I would drain the oil, then insert the boroscope cam in through the oil drain plug hole and see if the screw managed to fall all the way into the sump. If the screw it still not visible, then unfortunately, it seems that it would be necessary to start removing parts. I'm not sure exactly what would be next, but I'd think probably the oil pan (the oil pan is huge and there's lots of places the screw might be it it did manage to fall down there). If the screw fell into the timing chain area, then it would necessary to remove the timing chain cover. Hopefully you won't have to do any of that - hopefully you'll find the screw in the head and be able to pick it up with the vac. As you know, don't start the engine until you find that screw. I'm really sorry that happened to you! I dropped something into an engine before, too, and I know how you feel. Hopefully you'll be able to find it in somewhere in the head once you remove oil with the vacuum cleaner.
