My '03 C230 Coupe had a broken and cracked oil cap filler gasket (the circular one) leaking oil into #1 plug/coil but once replaced and cleaned #1 & #2 coils/holes the car runs like new. Now I gotta address the minor shaking when I turn the A/C on. Thanks for the help with the valve cover gasket.
I am currently doing this job on my 2012 c250 blue-efficiency. It has a turbo m271 so it's been a little different but actually easier for me, I didn't need to unbolt anything on the intake side at all. Right now it's all apart but it's dark so I'll have to come back tomorrow. And add my results. If I can find my gaskets I bought ages ago....
That little "pipe here" at 2.49 is a nasty one to put back on! I spent an hour trying to get the airbox into the upper supercharger rubber only to have the lower end of the "hose here" come off the lower section of the airbox. I literally learned how to do this blind, turning my fingers into effective eyeballs.
also replace the oil cap seal the oil comes from there too sometimes. i should have put sealant on the back left corner I'm having some slight seapage over the past year from that spot.
thanks for your comment. That seal seems to move and oil seeps through as you indicated, especially if one is pouring oil into the engine and some spills.
@@aydenhache5716 well if the oil cap is leaking get a new seal for it its cheap but for the valve cover I have tried 3 different gasket maker brands and they all kept leaking the way they make the valve cover the best bet is just a new valve cover gasket tighten to spec and you sorted. Also if you going to open up the valve cover after a long time you would need to replace the valve cover gasket again once they harden over time they are useless.
@@YusufPetersenCPT yes after further inspection it is all leaking from a ripped seal that hugs the oil cap, when the engine is running droplets seap out, valve cover is dry thank the lord but one of my cam sensors is definitely corroded. This video along with your comment has helped me quite a bit and likely saved me a lot of money at a shop! Thanks guys!
My OBD2 mounted on the dashboard had on one occasion alert me on a leak that had occurred on the PCV hose. During normal hot idling at 750rpm, on D mode, air condition switched on the MAF is 5.5 to 5.7g/second, MAP at -7.3psi, throttle valve body at 15+% open, O2 sensor reading at 0.65 to 0.7V etc etc.
Thank you very much for taking time to post this video. I understand everything, but what completely confuses me is when you say that care needs to be taken not to touch any of the oily surfaces with the underside of the cover when putting the cover back on. 7:28 Why, please?
thank you. The clean and dry side of the gasket must not tough any oil from the crankshaft or other parts otherwise it will wet the gasket and the seal will be compromised when you place the cover onto the head. The seal must be dry at all times. Sometimes when placing the cover one might brush past the crankshaft or other parts and a drop of oil gets on the underside of the gasket. That will be the first place for an oil leak.
thanks for your video. do you let the silicone that you put in dry before installing the valve cover? Or do you mount the valve cover right away before the silicone solidifies?
Great video! I hope you can help with 1 issue After I finished the job my car sounded rough on start up. The next day may car stalled on start up, then it started it the next try after that. When I drove it I had no boost but I can hear my supercharger. My car was slow 😂 but when I turn it off and start it again everything is fine. I have boost again. This happens occasionally but it never happened before this job. Did the job 2 days ago. Today I checked the vacuum lines, checked the electrical connections and cleaned them as well. Thank you.
Thank you for this video. How did you determine the valve gasket was the issue vs the head gasket? My 271 seems to be getting coolant into the oil, making the oil level rise while the coolant level drops. The dealer and an indy couldn't find an issue.
If anyone open M271 cover pls inspect the both sprocket of cam shaft adjustor. Whem my mechanic changes this rubber gasket he notice the there are a few missing teeth even there is no noticeble rattling sound. After taking it out noted that 21 of the 44 teeth on the inlet cam had worn down & broken!. Basically about 4 teeth broken on each of 5 separate locations around the sprocket! Engine had done 213,000km. Internal top & bottom of engine itself is very clean.
You don't. It's not necessary. However, it would be helpful for it to be able to be moved slighty so that you will have an easier time releasing the clip holding the wiring harness that's located between the valve cover and the air intake box.
What a thorough & clear video with just the perfect pace & A/V quality, w/o un-necessary comments/distraction!!! Two-thumbs up to you!
Thank you for an incredible video and perfect step by step.
thanks

Did you ever find out what the shaking was from the A/C? currently experiencing the same issue
@@KleiberM Same, I wonder if it might be worn engine mounts
I thank you so very much i follow every step and it worked out perfect
Much easier method. Thank you for posting.

What type of sealant would you consider safe? It looks like my oil cap is leaking but it could be valve cover I have no clue

Sorry Yusuf but I ended up not realizing if it's advantageous, if it's better, to use sealant on the back left corner or not?
Hi thanks for these vids they are very helpful. Could you show how to check for vaccuum leaks on the w203 , id be greatfull .thanks

Thank you sooo much from Brazil!
Question: Is it possible for this car to have a P0171 code due to the seal letting the oil into the spark plug area?
A very vid of how to this. I came across oil in the spark plug wells.. I now know what to do.. thanks

Good job, many thanks
thanks for your video. do you let the silicone that you put in dry before installing the valve cover? Or do you mount the valve cover right away before the silicone solidifies?
Great thank you for the video.
this helped my own car
What size sockets did u use to loosen the air filter screws ? E10 or E8?
great sharing video
Does throttle body cleaner be used if one doesn't have contact cleaner?
Baie dankie. Clear informative video. By the way you stop mid sentence, and wait for someone to finish, I'm guessing you were a teacher?
thank you, yes i am a teacher
Great video! I hope you can help with 1 issue

thank you. Scan it and see if there are errors.
very helpful....tq
Thank you for this video. How did you determine the valve gasket was the issue vs the head gasket? My 271 seems to be getting coolant into the oil, making the oil level rise while the coolant level drops. The dealer and an indy couldn't find an issue.
yours sounds like head gasket
If it was a head gasket then their can be mixing and oil in the cylinder if it’s valve cover gasket then the oil only leaks into the spark plug hole
Check your oilcooler. The gasket can be torn.
what is the torque value for the valve cover?
E8 Screws
Hello, I have been having a ticking sound coming from behind the engine. Have u ever experienced this? The ticking invreases with RPM
hi, not sure about that. are you sure its not from your valve train?
Could you show us how to take off the air intake?
How to change the crankshaft
If anyone open M271 cover pls inspect the both sprocket of cam shaft adjustor. Whem my mechanic changes this rubber gasket he notice the there are a few missing teeth even there is no noticeble rattling sound.

Hello,whats that liquid that hit the screws?
engine oil
Why do u have to loosen the intake for?
You don't. It's not necessary. However, it would be helpful for it to be able to be moved slighty so that you will have an easier time releasing the clip holding the wiring harness that's located between the valve cover and the air intake box.
Do flush the oil?
not needed
ready for another 300k miles 😅😅😅

So which component made your belt squeal upon starting? Lol. That's something I need to dive into soon.
seems to be a common fault, when you solve it, pls post your solution. thanks

i broke one of the valve cover screws 🥹🥹🥹🥹any suggestion how to remove it ! it has like 0.50 cm hanging out know its not flat broken in there !
help
what is the torque value for the valve cover?
