Sir, I just want to say THANK YOU for being so prescient about the PCV issue; When you provided this info hardly anyone was mentioning it which saved me all the trouble that now so many people had the misfortune to endure

[@apassionfortangling3671]

A guy that knows his stuff at last.. Thank you!

[@roadsonboard]

Thank you for this useful video! I have a newly purchased CLS 320 and was unaware of these issues. Thanks to your video, I will order the parts and thanks for showing how to do the DIY work which means I can do the work myself ensuring its done right.

[@lindsayrixon7402]

👍That is absolutely the best explanation of the PCV valve and the problems it can cause, well done sir. Thank you!

[@angellemon3423]

Dude definitely overlooked this when I redid my seals!!! You’re the man!

[@bobbaxter952]

Bit of advice as i've just done this job,have a solder bolt at the ready!!U'll get to that later,the large orange seal at the turbo,when you replace it it has little round raised location tabs that fit up into holes in the black plastic air induction plastic,inspect these holes in the air intake carefully for little cracks!! If the cracks are there melt them clised with a solder bolt,the new orange seal is thicker as it hasn't been compressed like the okd one,if you have any cracks in your black intake that meets the turbo they will spread and crack further when you tighten the jubilee clip at the turbo! The new seal is difficult to fit over the turbo as it's thicker,it puts a lot of stress on the plastic intake!!Be prepared for damage!

[@rafiekahmed8568]

Hi thanks for your very informative tip never taught that such a cheap part can cause excessive oil in the intake thanks

[@JorgeBrown]

Great clarification with this video, mate! Thanks heaps.

[@edysinsimon8646]

Excellent call! ANY diesel fuel system, particularly this diesel motor just requires an oil/fuel filter system before the fuel enters the fuel induction! The clean diesel fuel is paramount to your long term durability! Also...I just combine a water/fuel separator filter next to the oil bypass filter. It's just far more practical in terms of long term value/costs.

[@JamesParus]

the PCV also works as centrifugal separator. The suction is from the center high up. and the breather vapor is coming in from tangent. So oil is been thrown to the outer edge and drops down from the air. Then it leaks back down to the breather when you let of the throttle.

[@rafiekahmed8568]

Thanks for a very informative video I recently overhauled my om642 but couldn't figure out why the oil level was dropping but i did notice oil around the intercooler pipes

[@laisda3564]

You absolutely right , it’s very important to take a look about that partical component. But next time I would also clean that oil what still left there , because nobody wants fire ( hot engine + Oil) or maybe the connection from the Rail or the copper seal from the Injector is leaking that would be also dangerous.

[@doe8939]

Thanks I was able to change my pcv valve and turbo intake seal before the leak got too bad. Also put on a new egr and my engine has gotten more quite and runs better

[@danielnedelchev7344]

Great video! That absolutely helps me to do this maintenance by myself! My PCV is the same as yours and does not have these zip ties. Can you please share how did you remove the hose from the old valve w/o damaging it?

[@cappeto]

Hi. Great job on these videos. I really appreciate them. I have a 2008 GL320 with about 200K. I rescued it from an abusive situation. I have the swirl flap motor issue and did the resistor fix as a temporary solution, which worked but the vehicle still goes in to limp mode occasionally. Once I restart the engine it’s back in normal mode. I’ve checked the resistor value and it’s fine. I’m thinking the residual oil build up in the connector may be causing a poor connection sometimes. So, I’m debating the swirl flap delete. I also need to change the oil cooler gaskets so I’m following all your instructions on that including the glow plugs. My question is, what is the advantage of NOT deleting the swirl flap motor and instead cleaning everything maniacally, changing the turbo and air intake seals, and then monitoring for any oil leaks ongoing? Thank you. I realize there are no “right” answers but I value your opinion.

Hi, thanks for the videos. I have a 2009 E320 with the crazy side mounted filter housings. Can you show a trick on how to break the flexible air hose inlet to those to make it easier to pull out the housing? The driver side is particularly difficult.

[@toumassa]

Thank you for the video, Did you physically remove swirls or just blocked in open position?

[@JC-yt2pe]

Thanks, for sure! I just received my new PCV to change the older one. I saw in your video that you made some repairs in the air inlet, close to the MAF (both sides). I have similar problem in my OM642 (a6420900042). So, please, how do you fixed it?

[@marcustruman6108]

Right on the money, I got the small oil leak from worn rubber intake seal (orange) and subsequently the PCV valve failed.

[@rodrigofabregas7756]

Hi, and thank you for this video!. How much do you tight that turbo inlet clamp?...is there any torque spec. for the clamps?

[@TheDomin8rr]

I took some 5/8" high temp high pressure rubber hose to a oil catch can circuit then sliced tube between pcv & turbo midway & plumbed it in. turbo inlet very dry now more importantly valley below dry too.

[@Dima-jq3mj]

One word of advice... Make sure that the top part of the oil catcher, where it might have or has a sponge, never gets clogged. Otherwise, you will have oil come out of the engine through the dipstick tube or some other place due too much pressure inside of the engine. So, make constantly clean the oil catcher...

[@cmack864]

Any tips on getting the intake with the MAF’s to properly seat both air filter boxes? Always seems like it’s made just a tad too short to me and requires a lot of finesse to get it right.

[@MyScotty7]

Big thank you, video on this fault longer over due,I've deleted my swirl flap motor last year,I'm now having turbo problem i think caused by defect pcv valve

[@madmagyver9981]

I have a 648 and a 642. The gt2359v was coming apart @ 149k on the 648. I also have to rebuild the gt2056v on the 642 (160k) today. I believe the actual problem is engine oil quality and change intervals. I have had several 617 cars well over 300k without a worn-out turbo. I've put on 30k since the rebuild last year (05 e320 cdi) and the car is a rocketship. Zero turbo lag. I'm using amsoil signature series 5w40 diesel (suitable for dpf+def systems). So far no oil consumption between oil changes.

[@Mezmar165]

Thank you for the video and the parts info you pass on--saw my bluetec had quite a puddle of oil under it and after putting it up on a lift and investigating, pretty much came to the conclusion it was coming from the oil fill port--only thing I could figure would cause that to happen would be a clogged pcv valve. Parts are ordered--Thanks!

Hi man, thank you very much for guidance. I have done the job and is all good however when I replaced the main red seal on the plastic air inlet the plastic snapped :(. I have used tape around it for until I find the part. It is so expensive :( around £200. any suggestions

Thanks for your advice to becareful with this components. How do you know the PCV must be replaced? or just a preventive action? Should I also change the breather hose? BTW, I change these orange turbo seals everytime I change diesel filter, and I buy them at the MB service.

[@Dima-jq3mj]

It is more of a preventive action... Just make sure that you don't buy it from the dealer, it will cost you an arm and a leg. You can buy it genuine or OEM online for a lot less. I'll give you a real example, RBM of Atlanta Georgia, wanted a $1000 for a 220 amps alternator for a 2013 Mercedes Sprinter, while Rock Auto sells it online OEM (Valeo 220 amps new) for $380. Same exact part $ 600+ less than the dealership.

[@AndresK5Blazer]

Does this parts have an equivalency on the W166 ML350? Or this engine (evolution) doesn't use this PCV or Seals? Thanks

[@TheMrKordunas]

Does the newer version of PCV valve (Aluminum one with 2 bolts)work on the same principle and do you know does it have the same problem happening

[@Dima-jq3mj]

Yes it does work on the same principal... And yes it does leak oil with time and needs to be replaced. This is the reason why Mercedes requires a 229.51 oil for the diesel engines that have DPF systems. The 229.51 is a low Ash/Soot oil, which means that when it burns it has far less parts per million emitted vs regular oils. Most of the oil used by modern engines is used through the crankcase ventilation system, due to the fact that vacuum/suction of the engine is used to ventilate the crankcase of the engine. On older engines no vacuum/suction was used for ventilation.

Hi, I have the same car, same mileage. Had you had any fault codes? My E320 went into limp mode, and had 2 fault codes in November. After taking it to a shop, they replaced fuel filter, and checked for leaks, they claimed my fuel line was full of soot! It had to be cleaned manually. They replaced or so the receipt states the EGR cooler kit/seals and gaskets. I was charged half the value of my car! And I’ve taken it back 2 more times due to check engine light and limp mode, basically the same reason I took it to them in the first place. Last time they had my car 5 1/2 weeks, and replaced the turbo actuator at no charge,but it still wasn’t fixed. The manager told me it’s probably the DPF filter is probably clogged, but they are equipped to clean it. The mileage has improved, but still goes into limp mode. Latest code was P0299. That’s the first time I’ve had that one. Any ideas? I love my car, but I can’t keep spending thousands on it.

Hi I'm a car mechanic and I need your help! I have a mercedes C350 CDI and there is an oil leak from a hole on the engine block! This hole is situated on the right side of the engine (driver side) near the gear box just above the crankshaft sensor! If I bock this hole, the oil will start leaking from other sealings such as crankshaft sealing etc. I think there is a pressure being built inside the engine and I can't figure out how and why! Any advice please?

We are considering getting a 2008 e320 bluetec is it something you would recommend or should we go with the gas counterpart?

[@MrZombieCrypto]

the Diesel engine is hard to beat in terms of reliability, fuel economy, and power - if maintained properly. The biggest thing you'll need to worry about with the 2008 diesels is the DPF filter clogging or not regenerating - I don't believe the e320 has the adblue system. There are a few "Delete" options you can explore, but we haven't had any issues with our 3.0L sprinters we use for our delivery company - you can force DPF regen using tools like the iCarsoft MB2 via OBD

I did change the PCV valve on my 2008 Sprinter every 50k and didn't have any issues with DPF or intake manifolds. At 260k I completely modified the software and got rid of DPF/EGR/EKAS/TPS/Lambda systems. I would advise you to change the PCV valve every 40-50k, or every time you change the fuel filter. You can do about 50k, base on my own experience, on a good MANN or Hengst fuel filter. Your 2013 GL most likely takes this PCV valve...

I appreciate your video and hope you can provide some possible insight to a problem that I'm trying to narrow down. My 2011 MB Sprinter 3.0 diesel has a noticeable engine speed fluctuation while holding a steady throttle. It typically begins anywhere above 2000 rpm. This is a very rhythmic and consistent surge or fluctuation. This occurs when parked and not in motion, or when I was driving at 30 mph or any other speed. There are no apparent codes that come up. We've traced all possible sources, including getting the ECU retuned, replacing the turbo and the actuator. Any idea if these could be causing this surge?

Does the PCV affect your EGR valve ?

Thanks for the video, is this applicable to 2014 gl350 bluetec x166 om642 ? Do you recommend any oil catch can for this model ?

[@MBDieselFreak]

It would work fine for the updated om642 (2009+) as well, provided the oil seperator p# is the same. Oil catch can is always a good idea if it's installed properly, as it prevents oil vapor from entering the intake (the main reason for gummed up intakes)

[@kimballscarr]

@@MBDieselFreak I have wondered about this issue for some time. In the old diesels used in the 123 series cars (owned a '81 240d for 26 years... remained very much like new the entire time with maintenance) and my very elderly mom (now) having her 1985 5cly. turbo diesel coup still, local dealer keeps saying its basically new looking). Anyway, in both those cars which I have done the routine maintenance on (dealer has to do some things I don't have tools for). Never did the oil in the inlet, which exists all the time in higher volumes than the OM642 engine could tolerate, ever gum up or coke. In fact, there was no problem. I have spoken to some friends who have worked for diesel engine manufacturers in the engineering and test labs as engineers... not a problem in diesels, is the comment. In fact Bob ran the entire AirResearch test facility for nearing 20 years, and they did the development of the 5 cylinder turbo diesel under contract for DB / MB. The only issue Bob reported was getting the engines through the 1000 hr. full power durability test on the dyno. Why was valve recession. The German engineers felt the std. ductile iron valve seats were more durable in actual road use. However, when you run an engine at max power for long periods the valves tend to recede. The routine maintenance of valve lash does not work in those extreme conditions of power and duration. He would sneak in hard seats in those engines so they would not have cam/lifter surface failures and valve issues such as burned valves, due to inadequate cooling. How that relates here is that one wonders why these engines have gum up problems of intake system. Well they have a very high rate of EGR flow at certain points in performance cycle. This at low engine speeds and in stop and go driving puts upwards of 50% of the inlet air is recirculated (but cooled) exhaust gas. So why the EGR gas to ambient air cooler is lower than the intake manifold and intake charge valves. So it would seem logical that would gum up first as oil would end up there. Apparently, that is not an actual settling area and the oil mist must be heating up to the point to cause the oil vapor / minute droplets to be thickened and coalesce on the inlet surfaces. But if the cooler is working why would not it keep the temperature down from the EGR flow?

[@Docbrut]

Alex from LegitStreetCars brought me here and I'm glad he did! MBDieselFreak - I've got an '09 ML320 which has had the DPF & SCR & DEF systems deleted; however the car still appears to be burning a lot of oil. I'm about to replace the PCV Valve as per your video's recommendation but is there anything else that you may know of that could cause it to burn lots of oil; I have to top it up with a Quart nearly every 7-10 days! not sure if that's normal but it sure wasn't like the prior to deleting the DPF

[@MBDieselFreak]

Erik Fahlman are you absolutely sure that the oil is being BURNED? or is it possible that it's leaking when driving?

[@MBDieselFreak]

Typically burning oil is caused by bad piston rings or leaky valve stem seals.

[@Docbrut]

@@MBDieselFreak It's coming out the tail pipe and is blueish white in color so I'd assume it's burning oil

[@Docbrut]

@@MBDieselFreak I doubt it's either of those and hope it's not either of those because it didn't burn oil prior to having the DPF Deleted so I'd highly doubt in just one weeks time the rings were toast after deleting the DPF and having the SAM re-tuned. I'm lost for ideas!

[@budagen]

@@Docbrut My R320 CDI is also deleted. I also had the oil cooler seals replaced, you may be losing oil from there. Sometimes you don't see an oil puddle in your parking because the belly pan has these foam like material (for sound deadening) that can absorb any drippings.

Is there a similar part for the 2.1L

[@MobilediscowirralCoUk]

Do you recommend w166 from 164 or keep 164

[@ruantecillo2535]

hey, I have a 2009 ml320 3.0v6...I want to order the pcv valve however the website doesnt cover my year model. is it the same one? i can only see a small part of it since its covered with some bracket that holds connectors on top of it. it's made out of black plastic from the small portion I can see. what do you think?

[@Dima-jq3mj]

Post the last 8 digits of the VIN number and I can tell you which one to buy if you already haven't bought it...

[@taskhunters5245]

Hi Man. Did you actualy used recistor 4.7kohm to delay your swirl flaps??

[@kayakwesty]

Software

[@senseiDi]

I have a 2007 320 CID v6 on the turbo intake I have oil and it seems it`s not just from vapor .... need to check this valve .... hope it`s not too late !!! :D

[@MBDieselFreak]

It takes YEARS of neglect for excessive oil leakage past that PCV to cause any type of damage, if any at all! Just change that valve when you've got some free time, you will be fine. :)

[@senseiDi]

@@MBDieselFreak there is not a drop of oil on the engine or anywhere, just that on the enter of the turbo there is some oil so I'll just change that thing and lets hope the oil gonna be gone.

[@angrycatowner]

How did you delete the EGR and the Intake Swirl Motor? Doesn't the ECU check for it and show a CEL when its missing?

[@MBDieselFreak]

I didnt delete the EGR, the Intake flap motor can be deleted with a "resistor trick". check my om642 oil cooler seals video on how to do that resistor trick.

[@Dima-jq3mj]

He didn't delete anything. He simply tricked the ECU. There is no way to completely delete the EGR, as example. We call it a "EGR delete", but in reality what is done by tuners, is a remap of the operational programming of the EGR. The EGR is reprogrammed to stays closed at any RPMs or operational range of the engine. That is the same with the intake manifold flaps, they stay open at any operational ranges of the engine. DPF/ DEF and Lambda requires remap and delete of the DTC trouble codes, which simply means that the check engine light will never come on if you disconnect a Nox sensor as an example, because there is no code for that since it's been erased from the memory of the ECU. It is very easy to do modifications on EDC16 ECUs. EDC17 ECUs are a lot more complicated due to the encryption of the tricore chips/processors used in them.
