Mercedes Benz VALVE COVER GASKET Replacement MADE EASY | Mercedes Benz S Class S500 W220 M113 Engine

#Mercedesbenz #Mercedesbenzengine #Valvecovergasket
Hey everyone! Have you ever had that burning motor oil smell in your car while you were driving on long trips? If so, then it’s probably because your Mercedes-benz has an old valve cover gasket that needs to be replaced. That’s not a problem because changing the valve cover gasket on the Mercedes-benz s500 M113 engine is super easy. After changing the valve cover gasket and valve vent hoses on your Mercedes-benz valve cover. I would recommend changing your Mercedes-benz valve cover gasket and hoses every 50,000 to 100,000 miles because the rubber can get hard and it makes the job easier if you change your valve cover gasket before the rubber gets hard. Alright, let’s roll up our sleeves and go to work!

I have a 99 SL500 m113 one of the first things I did was removed the crankcase breather cover from valve cover cleaned out sludge and drilled out that hole you referenced with no negative consequences as far as I can tell. It’s a known mod in the M113 community. 50% recommend with logical mindset why you’d want to. 50% are old guys who say “MERCEDES DESIGNED IT WITH THAT SIZE HOLE FOR A REASON, ALTER IT AND YOUR CAR WILL IMPLODE KILLING YOU AND ANYONE WITHIN A 5 MILE RADIUS” so yeah. lol

[@FlacK88-ek8vg]

That's a mod I did on a GM3.6,I have a ML430 would that be a good idea,I knew to Benz,in NZL also?!

[@ericthornton7847]

Well I did the job, took two days for me. Cleaning parts was the longest part of the project. Changed oil as well and wiped up the oil on my undercarriage. This video was perfect, I had challenges with the hoses and watch more of the video and worked through it. Thank You a Bunch for posting this, PERFECTION.

[@GarageDynamics]

Congratulations Eric Thornton! Two days is normal. Usually you do one side and then finish the other side the next day. And yeah, those hoses can be a pain to remove haha. Thank you for the kind words. I'm glad this video could help.

[@ahmadsaleh9635]

1- That attachment is called breather cover (it's the same thing as PCV valve in other cars, separates oil from the air) 2- If that small hole gets blocked it causes multiple issues : a- P0047, P0104 b- Once in a while the blockage would open on its own and it would suck in a bunch of oil which ends up straight in the intake 3- Degreaser followed by tyre foam cleans these oil deposits really well

When removing the upper breather cover I found it best to use a heat gun makes it a lot easier. Great video production was excellent ... Very informative

[@anthonyorafferty5632]

'Heat gun ' great tip thanks

[@Menga213]

what type of gasket maker did you use? what type do you recommend ?

[@outofthinair1]

@@Menga213 I used the Mercedes approved gasket material. it's expensive, somewhat hard to get out of the tube and has a short working time but 4 months later no leaks. The most important thing to bear in mind is the cleaning of the gasket surfaces. Make sure they are totally clean no grease or old gasket material. It sounds easy but I spent about an hour on each valve cover. Make sure you follow the torque specs. Good luck with your project, and take your time,

[@sl5311]

@@outofthinair1 When I took my valve cover bolts off they were barely tight-is this normal?

[@outofthinair1]

@@sl5311 Totally normal, mine were loose as well. The engine heat, cool, cycles shrink and hardens the gaskets. It's not a horrible job , it's just time consuming. Make sure to replace the aluminum breather cover bolts. Good luck on your project.

[@joepacheco5771]

I'm doing the same job on my 99 SL500 based on your video. I going to suggest you put a rag or old shirt on top of the exhaust to avoid oil falling on it. And if it does, well, you're covered. No need to clean afterwards. Another thing I did when taking the fuel hose off. I cut a small piece of a plastic water bottle about 2" from the bottom and place it under neath the hose intake to collect the gas that will drain. As it gets full, plug the hose back up and drain the gas on the other half of the bottle. Of course, it will be up-side down, but it works. You will have a bit of spillage but you use the gas to clean the covers, specially where it's full of thick grease. I also cleaned the cover (s) with awesome cleaner which you can get at the 99 cent store. Thank you for posting your video and hope this will also ease a bit of the work and mess.

Thank you for the kind words Dustin 🙏 I would recommend cleaning the engine with Purple Power or Simple Green Professional engine de-greaser. I recommend using denatured alcohol and scotch brite pads to clean the metal contacts on the ignition coils. Then do a final cleaning by spraying the coils with electrical parts cleaner. I hope this helps. Cheers!

Excellent video I have a 2004 MB SLK 32 AMG I think I have a small valve cover leak, There is a bit of oily smoke after it gets heated up rising from under the hood. a little bit of weeping oil only from the bottom edge of the smaller valve cover that sits on top of the main valve cover on the drivers side. I removed all the top air intakes and the coil packs and confirmed that this seems to be the only leak. I thought of just tightening the small valve cover a bit more but didn't as it might just make the leak worse. Is it possible to only remove this smaller cover, clean up everything and reseal it without disturbing the main valve cover. Would you you do in this case is is it just better to remove all of it. The Right side valve cover seems to be fine. Since there is no factory gasket for this smaller valve cover piece on the left drivers side what is the best sealer to use for this ? Would you also still replace the two long top bolts that hold this piece with stainless. Thanks for the excellent video. SK Ohio

[@GarageDynamics]

Hello Steve K, Thank you for the kind words :) It's possible to remove only the small top cover but it's possible that some of the silicone will fall into the main valve cover area while cleaning. If you are sure you can clean and replace the cover and not let debris fall into the valve cover then I say to make your decision on how confident you feel. Personally I would remove the whole valve cover and then clean the small cover very well, which is necessary for a proper seal when applying new sealant. Also, please do not tighten the valve cover bolts as this could possibly damage the threads. the main valve cover bolts have a torque rating of 9Nm and the small cover has a rating of 4Nm I believe. This is a very small amount of pressure. The small cover bolts are one time use bolts and over tightening them could damage the threads. The silicone that I use for the valve cover is VictorReinz Sealant: amzn.to/3Pz0ji1 I hope this helps. Cheers!

Hello Andrew Weaver, Yes, the valve cover on the Mercedes-Benz S Class W220 is made of magnesium. This metal will react with other metals and certain chemicals. Stainless steel does not react with magnesium. Aluminum is safe to use as well, but carbon steel and copper will react. Keep in mind that magnesium is very brittle and harder metals can case damage if over torqued. When using a cleaning agent, it's import to use a mild soap without acid. I hope this helps. Cheers!

Ah i see thank you for the insight

Did you take the oil out of the motor I’m going to do this pretty soon and I don’t know leave the oil in or take it out

[@GarageDynamics]

Hello Sophia Lee, I left the oil in the engine. For valve cover gasket replacement, it is not required to drain the oil. I hope this helps. Cheers!

Do you have a video or link for mb gl350 w166

[@GarageDynamics]

Hello paul torres, At this time I do not have a video for the gl350 w166.

lot aplication of silicone ? Look one of Honda only a few points of contact , for cost will be interesting ?

Mercedes Benz uses LOCTITE 5970 (BeVo list) Best regards from Germany by Michael 🙌

[@dawsonwilson7592]

Only problem with the video, you never took a mirror to the VCG to check for a proper seal before torquing. Other than that not to bad. Would also recommend doing your plugs and leads while you are there. If you’re leaking oil, need to make sure it’s not on the plugs

Hey man I was wondering if you can help me . I have done a complete tune up to my car even fixed a misfire on cylinder 5 . But I seem to no be able to get the performance I need from my cl500 . Once I go up by 50 mph or 4000 rpm my car shakes or jerks while in motion but than I lower the speed and seem to maintain to it's normal capability. But yeah not being able to go pass 4000 rpm

[@donkmeister]

Have you checked the engine mounts? Open the bonnet, and watch the engine as someone in the driver's seat presses hard on the brake pedal whilst putting it in D and giving it some revs then doing the same in R. If the engine looks like it's jumping out of the engine bay then you need to replace the engine mounts (and worth doing the transmission mount at the same time). Quite common on the 500s and so easy to check! If not that, next thing to check is the harmonic balancer.

[@rudyramirez6162]

Thank god , but I ran into another problem. Seems like the old owner of the cl500 never maintained the car. I had a 3 way heater connector hose crack on me , a thin link feack is causing my cat to over heat and release hot water. I ordered the parts as well for my transmission conductor plate for the speed sensor. Let's see if I can finally rev full potential and get it free way ready . Fingers crossed my guy . Tha is for caring lol

Did you ever find out whether those breather cap holes could be drilled?

[@GarageDynamics]

Hello Sakeenah Auto Solutions! Not yet. I think I saw someone mention in the comments that they drilled out their breather cap hole and had no issues. I will perform this procedure later on with a separate breather cap. Then I will keep enlarging the whole little by little until i run into a problem. Once I know the optimal size I'll let you know. :)

[@Usmanthemecano]

@@GarageDynamics lol I'm doing this job in a few days but thank you though

[@outofthinair1]

@@GarageDynamics if the holes are enlarged too much the additional unmetered air will cause a lean condition and possibly introduce engine oil into the throttle body and intake with the increased suction ... Tread carefully when doing this ....

[@Mercedesdriver2012]

@@outofthinair1 Absolutely correct 👍. Mercedes has enlarged this hole somewhat in the second valve cover generation. But just a little 🙏🙏. Please do not drill completely. That causes big problems with sucked oil. Best regards 🙌 Michael from Germany

[@tinoracing7]

Do those coils fire at different timing or do they fire at the same time

[@GarageDynamics]

Hello tinoracing7 Yes, I believe so. Because there are two plugs per cylinder they will both fire at the same time.

[@mzee5533]

Is it really necessary to apply some little bit of silicone on the face of the gaskets

[@Leonardo555ZZZ]

No ,, a little between the gasket and the cover is ok ,,that is where they leak.

[@outofthinair1]

I would suggest buying OEM gaskets and careful cleaning, I just did my m112 ML320 with no leaks... I did not use gasket sealer on the main valve cover gasket ... I used MB high quality gasket sealer on the upper breather covers ... cleaning is of utmost importance it took about 2 hour just to clean the valve covers

[@Mercedesdriver2012]

@@outofthinair1 Done right 👍. The original Mercedes seal is = LOCTITE 5970. Wait at least 12 hours before the engine is started. Best regards from Germany from Michael 🙌

[@sl5311]

@@outofthinair1 still at it here, did you use the heat gun to the stuck pieces of the gasket off? They are tougher than I thought on mine.

[@outofthinair1]

@@sl5311 A small brass wire brush, brake clean and a lot of time is the only way to clean the gasket material off of the upper breather cover surface. As I said previously it took me about an hour for each valve cover. It is a pain in the butt to get the old gasket material off . You could try the heat gun to soften the gasket material but time and above average effort is what will get the job done. Best of luck on your project
