Not so hard, a bit long and messy project but so satisfying at the end, I highly recommend this and have seen many of these M113 and M112 Engine dirty engines due to the valve cover leak. Doing this along with the spark plug replacement (12 for M112 and 16 for M113) will save you literally $1000 in cost as these 2 projects are labor intensive... Good luck and please share your experience. Thank you.

Most likely your rough idle is a bad egr valve it’s a common thing that goes bad I herd or your breather valves are plugged up cause there are little holes that let exhaust gases through into the main valve covers .

Good job ! I have done this on two CLK320's and a CLK55AMG , it is a long process if you want it done right. My only tips , the breather cover bolts should be replaced with stainless steel bolts to minimise corrosion , and I would use only 3Nm to ensure that the magnesium cover threads don't strip. Also clean out the thread holes of any old sealant so the new bolts go in ok. This job is normal maintenance on these engines after around 15 years or so. Another thing you should do is replace the Crank Position Sensor , they also need replacing every 13 years , regardless of mileage. Use genuine or Bosch only. Also replace the air filters and cabin filter , which are always neglected.

Would there be a mfg date printed on the crankcase or crankshaft position sensor. If yes, easier to make the decision to change it or not.
@BenzAddiction
@BenzAddiction Жыл бұрын
@whlawson probably not very related to this topic and I have another video on this but if you ask AI this question about the expiry date on any cam or crankshaft sensors it would say: No, the Mercedes W209 crankshaft position sensor and camshaft position sensors do not have an expiration date. However, they can fail due to a variety of reasons such as wear and tear, damage, or electrical issues. Routine maintenance and timely replacement of these sensors can help prevent failure and ensure smooth operation of the engine. It is recommended to consult a certified Mercedes technician for proper diagnosis and replacement of faulty sensors.

@@BenzAddiction recently I bought a set of PCV & hoses for my mechanic to change out during oil change for supercharger. It turns out the previous owner had changed it out as the mfg date printed on the old PCV valve is 2+ years after the car's registration date. So if there is a mfg date on the position sensor I will not buy a new one until I could verified that the mfg date of old sensors on my W211. If it is mfg in 2011 or later then no need to replace it for the time being.

For the breather covers, it’s important to allow the sealant to cure for 20 minutes or so before reinstalling them on the valve covers. This allows the liquid to set a stronger bead against the metal as you torque the bolts tight.

@@gangalee83 Getting ready for this job myself. Hopefully someone responds, but it seems like you install the breather cover after the silicone, install the bolts for alignment, but don't tighten. The silicone has time to form up and then when tightened fully, it will be firm instead of squishing out. I am just getting that from the context of the two comments, and thinking about it. Like I said, hopefully someone affirms this.

So, I watched your video prior to attempting this on my W211 E500. However, when I got into mine I found that you don’t need to remove the coil packs, spark plugs, fuel rail, etc. Just shift the coil packs around to reach the bolts and replace the plastic hoses on the breather covers. The coil packs, when shifted down far enough, allow the valve covers to clear out of the car, the only connections I had to disconnect was the coil pack harness and the fuel line at the back. Hopefully this comment saves someone else a few extra hours of work.

@@bleachstain9785I have done this by simply leaving the coils hanging on the plug wires. I have slightly bent the fuel connection up a bit and now the cover can be installed without disconnecting that. Before bolting, use a mirror to make sure gasket is in position esp at the back lower corners. My PCV covers were sealed on with RTV (ultra black or ultra coper)long ago and it leaked (may have been a long time). Now I only use the 'Right Stuff.' The 'Right Stuff' costs more but is much more like the OEM sealants. It is the only thing I use on critical jobs now. It is much harder when cured, like the stuff when you are the first to pop a factory cover off.

Great video!!!! Just some advice to share from my toiling :) My 2005 clk500 cabriolet: The key to removing the spark plug wire off the plug is a THIN wrench & may have to shave/grind one side just abit to fit the tight side of the metal plug boot. I used an 11/16 wrench that I had already shaved a side 20 years ago. 17mm open end fit well too. The coil pack harness can be left attached to the coils, they will be able to be set up on the intake while you work. Just remove the plug wires from the coils....they are MUCH easier to replace instead the wiring harness connectors :) Edit: BTW to remember the spark plug wires location per cylinder....back plug goes to the bottom connector of the coil.....back to the bottom. And only remove one cylinders wires at a time....they seem to be specific per cylinder.....and use dialectric grease on both ends (need a LARGE tube of it LOL). Should make next plug change easier!! As for the valve cover gaskets only use gaskets from mercedes....I tried cheap ones from autozone & they just weren't thick enough to not leak a little....even with a redo with copper RTV smeared on the head surface or the gasket itself. I had no luck with after market gaskets....and I used no adhesive or RTV on the mercedes dealer gaskets & they worked fine for me...your results may vary so... WARNING!!!! Keep an eye on your gaskets for oil leaks as you run the engine for the first time!!!! Oil WILL catch fire on the exhaust manifolds!!!! So watch for about 30 minutes at idle & several revving cycles.....and I shut down & let the engine cool & ran it again the next day & caught the leaks BEFORE I drove around.

Amazing video, I am unsure that you did the bolts up in the right order, as usually you work from the middle outwards in a zig zag fashion, to avoid twisting the cam cover, haven’t got a service manual, so cannot confirm this but would seem wise

Nice tutorial, thanks for that, but I have to correct the torque specs, because MB manual says to torque T10 screws to the 9 Nm. 8 Nm is for coil packs. ;) For those aluminium screws it is 4 Nm and they should be replaced and also should be aluminium. If you replace them with stainless steel, the torque is out of specs and you can simply demage the thread in valve cover. MB put this screw material in for the particular reason, so...

That's not really how it works. If the female thread holds an aluminum screw, it will hold a steel one better. The same torque spec will be fine. See Shigley, Mechanical Engineering Design to learn more about threaded fasteners esp preload and how the threads distort during loading.

Because they are morons. Honestly, they probably wanted the assemblies to meet 'easy recycling' criteria but instead they just increased the demand for non-critical aircraft aluminum screws in a situation where the dismantler could quickly and easily zip out steel screws. Bad engineering like the rest of the car.

Replace the screws and/or be extra careful. Use Yamabond, The Right Stuff, OEM factory, hondabond, threebond, etc. I used the best regular RTV (ultra black or ultra copper) and it leaked after a long time. The ones I named first are different.....they are the harder, less rubbery, more crumbly (when you clean it out), less stretchy (when removing) than the regular (even premium 'ultra' and 'more oil resistant') types of RTV. I would also recommend the right stuff when gluing up critical things like automatic gearbox, bevel gear, transfer cases, newer final drives (the old style axles with the big flange seal fine with the old rubbery RTV)

Tha aluminum bolts for the breather covers must be replaced with the same aluminum bolts from Mercedes and not steel bolts. The reason is that these covers are made of magnesium, and steal in contact of magnesium causes oxidation, further deteriorating the cover bolt thread, loosing the cover and gasket causing earlier oil leak. Also, for these covers, don't use any other liquid gasket but the one from Mercedes. If you do, you'll regret as I did.
