Mercedes Oil Drip Pan | PCV Replacement DIY 

Keith, Thanks again. Another excellent video. I had followed your perfect instructions for replacing the air intake manifold then watch these and followed their instructions as well. No one makes videos with as much attention to detail as you do.

I changed the oil drip pan and breather port on my 2010 ML350 today. It wasn’t that bad. It’s just a little tight back there. so one thing I noticed in the video is that you said to take the bolts off by turning it clockwise. I realized that you would be turning clockwise if you were standing behind the engine. Since you were standing in the front of the engine, it would be counterclockwise to take the bolt off. Meaning turn the socket to the left to take it off and to the right to tighten it back up.

Changed this entire PCV system without any issues thanks to your videos. Thank you sir!

My goodness you're a genius man. I just got my intake manifold swapped for a new one, and I go and do this test and there is oil in the hose! Going to get it changed asap to avoid damaging the new intake. Thank you again so much for this valuable information!!!

Keith, I just replaced the oil drip pan and cover on my 2011 S212 E350 as it was approaching 100k miles and wanted to change it before it failed. Thanks for your informative video which made changing it a breeze.

Just did this on my 08 E350, thank you for the how-to! You're the only person I've found that posted the whole process, not just the cover. Keep up the great videos!

Thank You for showing the replacement of the spinner. So many videos and most don't even mention it. Then one did mention it having left handed thread. Now I understand the spinner sits against the cover (opposed to fitting inside).

Great video and instructions. Changed my oil separator and cam plugs today. Easy job took me 1 hour start to finish.

Excellent vid! I bought a 2012 c300 and after a trip to canada I noticed some oil leaking. Found your video, took it to my bro's garage and confirmed this was the problem. Thanks again for suck a great video and saving me from having to take it to the dealership! Mvto Mvto

Your video was a lifesaver! I would have screwed it up if not for you 😄Thanks so much for taking the time to make the vid.

Amazing video. Thank you Sooo much. I had to replace my intake manifold last year (2006 ML350) and replaced ventilation valve last summer. After watching this video, I'm going to replace ventilation valve again as well as the drip pan. Thanks again!!!

Easy as pie on a 2011, w212 e350. Four e10 (or 8mm box end) gets the top piece off. One reverse threaded bolt using 1/4” deep well socket gets the oil catch can off. Mine was not very tight. Thanks Keith!! No more oil on the exhaust.

Great video.....Thank you.....you are going to save me $$$$$$.....Also, big thanks....you are the only one who shows where this part is located.

3:15 that quater inch six pointed socket it also know as Female E-TORX 8 or inverse torx 8. that is what we name that socket here in Europe. Thank you for this video, i was able to finisch this repair today :)

Nice video. Many thanx. Good & informative DIY replacement of the PCV/Oil drip Pan !!

BTW a 12 point 8mm opened end ratchet wrench worked well to remove drip pan/separator cover. Thanks for this video. My 2012 GLK 350 oil drip pan did not have a groove only 54k miles.

Thank you. Great instruction. I used a 1/4 inch wrench to remove that hard to get bolt on the breather.

Great Video ! Well done! Time to switch this part out!! Thanks again !

Another great video. Thanks for sharing your knowledge!

Great information. Will do this on my GL450 soon. Your a great tech...

I have a 08 e320cdi with the om642 engine. I have recently changed the rebreather. The one I got is an updated version, where the breather and the drip pan come all in one. Mercedes thinking behind that must be that they reckon that the breather and drip pan wear out at the same time. The nice thing about this is, when I fitted the the breather, I had fitted the new drip pan too.

Really good job.. tight back there...gotta get drip pan..thanks

Thank u for doing this

hi! what kind of a camera are you using? it seems to fit in the tightest of the engine bay! good video and instructions.

Excellent work...

I was just trying to remove that 1/4" bolt and I remembered you mentioned it was clockwise to remove it. So I had to search for this video again to verify. Thank you! Someone put torques bit on the cover, instead of the ones you have. Makes it really difficult.

Got a 2008 CLS 550 need to change crankcase valve this video helped a lot didn’t even know about the oil drip pan or how important it is to change the dealer will never tell you that thanks man

Your a savior ☺️ for us DIY

You're good !

On a w211 m272 bolts are T27 on cover. E8 on oil drip pan bolt, or a 1/4 hex will work too.

Hi I have an SLK230 R170, will this be a usable fix with my engine? By the way great vid!

Hello man, thanx for the exelent tip and video , i got e350, and got bad smell from exhaust and machine is eating oil , do you think its pcv valve ?

hey man thanks for the vids they are definitely helping. That centrifuge that you show at the 4:06 mark is any part of it supposed to turn with the engine off or does it spin when the engine is on? I ask because supposedly a mechanic replaced this for me in 2018 but my hose and cover have oil in it, the gasket in the middle is not snug around the centrifuge which seems like they should be for something done in 2018, only 20,000 miles have been added since. Wouldn't a tech change both cover and centrifuge together vs just the problem part? or can they tell and only change whats needed at the time? thanks if you an answer and be well just the same if you cannot. Either way my manifold is currently on the floor of my garage covered in oil inside and out. The air flap actuator lever in the front broke and the other two are gummy to say the least. Still wagering on whether I should replace and recon the plastic bits on the front of the manifold or just get a new manifold.

great work! liked

great work bud!!

I just realize that the part you are holding is really suppose to save and prevent oil from going into the MAF and into the intake manifold. The part suppose to drip out and spinning out any oil collected. However, that is not enough. Have you install a catch can? I been seeing this quiet a lot and thought this might be a perfect application for this issue. Just a thought, what is the construction of the oil drip pan. How does it looks like from the inside?

Hey Keith..love your videos they’re amazing and have helped immensely pls keep them going! I have a CLK 280 W209 2007. Had the oil drip prob onto cat and had leaky cam plug cap and PCV cover. Two questions; my mechanic took off the the PCV cover and the gasket was worn causing the leak, he said don’t change the oil drip pan no need and would also mess with timing. Also the three cam plug plastic caps I changed the two small ones (one was leaking). Cannot for the life of me find the large plug cap, is this missing on some models depending on year? In your video it’s in the drivers side next to the smaller one but cannot find it on either rear side of the engine. Many thanks 🙏🏼

What tool did you use to remove crankcase breather?

Thanks.. nice bike too

Great video ✊🏿👍

A couple of questions. 1) At the 4:39 minute mark, there is a grey harness to the right of the screen sitting on the transmission bell housing. What is that ? Mine is tightly against the PCV cap, turns and runs along the sides of cyl 1-4. 2) The drip pan seems to have been redesigned slightly (oil exit holes). Is there a reason for this redesign ? I have a 2010 E550.

What do you think about using a catch can in this hose?

have these things been the same or similar design on earlier e320 models? do the w124s have a similar part?

Can u replace coil with any cool t or it's a specific cool for each

Great video as I noticed oil somewhere and changed the separator but in oil pan and just changed it this evening now I’m mad cause i have to go back and replace oil as I noticed it dripping down to catalytic converter. I need part ASAP and replace

The bolt that holds the oil separator wheel on is reverse threaded.

You are Great.

Is that factory device as good or better than a dedicated oil catch can?

This is a useful video. However, when I followed this video, the REVERSE thread screw present in this video was NOT present in a 2014 GLK350. Ask me how I know. I snapped it off turning the oil drip plan screw clockwise, thinking I was loosening it. Obviously, you think it was stuck and so more torque to remove resulted in breaking the bolt. After several hours, I was able to remove the broken bolt with a flexible extension attached to a drill and a right angle attachment with a broken bolt extractor to remove it. What a pain!

Wow should i do that on my 08 c300?

Hi Keith, Do these parts exist for 2006 ML500 & ML350? Thanks,

what size of socket do you use to remove the oil drip pan bolt?

Great video, as usual. After this is done, is there any way to do at least some cleanup of the oil/carbon buildup in the intake manifold and intake valves without having to remove the intake manifold? I see videos of people dropping water through carburetors on warm engines to cleanup carbon in the intake; is there a comparable method for cars with fuel injection and MAF sensors that is safe and effective?Thank you again for a great job.

Hello it's jammell can u tell me the how the engine could are numbered on a v8 engine in what order are they if u are standing in front of car

Love it...thx

Thanks for the great videos ! Question, Other then oil in the breather hose, are there any signs or systems or performance issues that would tell us these parts have failed?

Hi Keith, did a new reverse thread Bolt come with the oil separator? I just bought a new one "Mercedes" and no new Bolt in the Box. Thank you for all your great Videos! Keep them coming! Wish you were near me to help record my GL 450 repairs. Their have been Plenty. Long Island NY Thanks again.

The PCV valve and its diaphragm is the culprit, not the internal part in metal rubbing against the soft plastic diaphragm. Replacing the PCV valve it enough. But thank you for the reminder of reverse thread.

What is the inner bolt size of the oil separator , I’m using deep well 8mm and it catches but doesn’t turn do to it having star points on it aswell . Would a ser of deep well e torx E4-E8 would they work ? But what is a generic version so I wouldn’t have to wait for shipping please

Does the 2005 c320 4- matic have one of these?

this thing is on diesel engines or on petrol too sir. I have a 2004 merc 200 petrol.

How does that metal shaft wear down from a plastic rubbery diaphragm? I should probably do this. I've already had intake flaps replaced at 90K.

I have w203 yer 2005 i need to change oil drip pan bat my car is with diesel not petroil. Is this item for my car or not?

Is this for the OM642 engine?

thank you so much,,, do we really need to replace the oil drip pan since i don't see any seals on it, i do see the seal on the vent cap though, thank you

Does 2008 Gl550 have this part where can I can email you my VIN?

Man, I Wish it is this easy on the Newer M276 Engine. It is Unbelievable The location and procedure they Placed/set to replace these 2 Parts on the M276 engines..

I have no luck unscrewing the oil pan bolt. Tried it many times but it is too tight to turn loose. Any suggestions?

I dropped the drip pan bolt what size do I need? Please help

Any videos to do this on a M276 2013 C300

We're is this part located on my 2006 s500 4matic.

Keith - thanks for the video. Very helpful. Had some leakage bottom of rebreather cover so decided to replace it and the centrifuge. No issues taking everything apart but the new centrifuge would not seat onto the camshaft no matter how much I fiddled with it. I ended up putting the old centrifuge back on (it seats easily) and buttoning everything back up. Any trick to get the new centrifuge to properly seat on the camshaft?

Is this part used on a W210 M112 (1999 E320) engine? I don't see it at the end of the breather hoses.

Thank you! Would have likely stripped or snapped the bolt trying to turn it the wrong way if not for your video!

Hey is the centrifuge piece that tightens down left hand thread. Is it suppose to be just right enough to spin it freely or should it not have any movement to it???? Please help, any advice would be appreciated.

I didn't get a new bolt for the oil separator, just reused the old one? Is it gonna be a problem in the long run? Thx.

Should I lubricate the diaphragm on the rebreather before installing it on the drip pan?

So, if I got this right this "rebreather" must try to take out the oil from the Crankcase air (like a PCV system). If this rebreather etc is replaced is there really a need for an oil catch can? Is this the m112 engine or the later ?is it m272? Cheers

Thnx for ur video is there a way you do this on the side?

Would a faulty pvc course a black puff when you put your foot down? I've 270 CDI

What are the signs in your car's operation that this needs to be done. Can this be the problem if I'm getting white smoke on the start up in the morning or when my car is cool?

Question...Should you not clean the re-breather hose and the mass airflow sensor and the throttle body as well?

I just had this repair done by an authorized mercedes repair shop (2008 ml350) but now it's burning oil . I don't know if one thing has anything to do with the other but seems odd that all of a sudden I'm seeing smoke out the exhaust and I'm topping oil every couple of weeks. It does have over 100,000 miles on engine.

Is that 10 inch pounds or 10 foot pound

💯👌🏾👍🏾 your great

Hi Keith Iam replacing the intake so off course I decided to replace the oil drip pan and cover. S!@# i broke the bolt that is suppose to go clockwise. Any ideas u might have would be greatly appreciated. Thanks

Hi there! My C280 has the OIL DIPSTICK TUBE omitted! Can I still use and extractor when I change the oil?? I've searched high and low to figure this out!

I changed mine both the pcv and the oil separator, the car still smoking on cold start, by high revvs and hard acceleration.. ( E63 "12 M157). Do you think it might be a failed valve stem seal? Or I didn't change the pcv and the oil separator correctly.

I’m not sure, but I think you have to replace the lower valve as well on the driver side

I have a ‘01 c240, this is the first time working on one. does anyone know if I even have this or is this part on all Mercedes?

How old is that drip pan that it has the groove warn in it

What Mercedes-Benz Engine? Look like M272.

I used a 1/4inch socket but it rounded the bolt holding the drip pan. Any recommendations how to get that bolt out?

Did 2011 E350 had this issue?

At what mileage interval should I be replacing these two parts? Thanks.

why you dont explain the ml320 engine model?

Do you know what's the problem if my hood is stuck and won't open ,it will release the driver side but not the passenger side any clues

Did you have any issues with the oil separator at all??? Im about to do this to my 2011 Mercedes-Benz E350 4Matic.

Is this the same on OM642 engine in a W164 ?

Also, Apparently, I'm looking online and it says it's the same part for the Oil Drip Pan for 2006-2016/2017 Models.. ??? However, yours has a different part number..??? Anyhow, this and one other YT Vid is the Only video/Picture that I could find Online regarding this Oil Drip Pan (Or Centrifuge - I believe)- As it's called on the newer engine... But, I'm looking at this part and I can't figure out how it works and you didn't say either. Looks like it bolts onto the back of the Camshaft. So does that mean the Oil Drip Pan Spins/Rotates along with Camshaft while in Operation??? 🤔🤔🤔 Hope you can give some insights - I'm trying to determine if Mine needs to be replaced at Only 50K Miles. Engine Shakes while Idling I noticed that there is a restriction in the Breather/PCV hose/Line and I don't think it should be, I've ordered the Breather Cover But I'm trying to determine if I'll also need the Centrifuge/Oil Drip Pan... Car is a 2014 Mercedes C350.
