This is the Secret to a clean Engine (M113 & M112 Valve Cover Gasket replacement), These 2 Mercedes Engines are notorious to leak oil and drop oil on exhaust manifold and ultimately smoke coming from engine compartment and burnt oil smell from the AC vents.
The Rocker cover / gasket for these v6 and V8 engines are not the best design and after few years and some thousands kilometers they start leaking oil.
These engine are used in the bellow cars:
M113 Valve Cover Gasket replacement
M112 Valve Cover Gasket replacement
500E
E500
SL500
CLK500
S500
CLK55
CL500

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.

@patienceisalifesaver9582 Месяц назад

Can this cause rough idle? I don’t have any vacuum leaks from hoses

@talklacey664 Месяц назад

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 .

@Leonardo555ZZZ Год назад

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.

@BenzAddiction Год назад

Very good tips, thank you so much.

@whlawson5812 Год назад

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 Год назад

@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.

@whlawson5812 Год назад

@@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.

@BenzAddiction Год назад

@whlawson yes, good preventive measure to replace if they are so old. I keep 1 of each in my Glove Box, not difficult to replace.

@wizardindustriesusa Год назад

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.

@BenzAddiction Год назад

Very very correct, I am sure I have tightened those bolts in 3 stages...

@gangalee83 2 месяца назад

So put the sealant on, then wait 20mins before putting the cover back on?

@shnitzel14 Месяц назад

@@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.

Also, while this is apart, don't forget to check the integrity of the gaskets at the MAF and at the elbow to the throttle body. Clean the MAF, too. Two new pliable rubber gaskets are not that expensive and are well worth the time and effort, especially if they have never been replaced.

The five bolts need to be aluminium (genuine) stainless steel. The covers are made from titanium and steel bolts will cause bad corrosion. Correct torque specification is 4Nm for the five breather cover bolts.

@williambrandt9254 11 месяцев назад

Nice video. Thumbs up! I might add that if you have used a good synthetic oil like mobil 1 the inside of that valve cover would be spotless. I recently replaced the valve cover gasket on my M119 SL 500 at 236,000 miles and it looked brand new it has had mobil1 since the new as has my 2000 E430 with the M113. I suspect my M113 engine looks similar I think with FSS aren't they recommending synthetic oil? But anyway a nice video and well presented - thank you

This video gives great information, so thanks very much! One question, I'm hoping I won't have too much gunk to clean, but does it only accumulate on the insides of the covers, or will it also need cleaning off inside the head? And what's best to do that with? Thanks again, and I've subscribed to your channel as I'm sure I'm going to need more of your information in the future.

@nopeno6514 9 месяцев назад

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.
