How to inspect the oil separator before doing any replacement ; Most of the time the O rings or the gasket becomes brittle and allows leacks to occure . So on this video you will see how to replace the oil separator / crankcase breather gaskets on this Mercedes w210 e220 , e270 e320 CDI . with the om646 engine . It can be confusing since the same part can be found under 3 different names : PCV valve ( positive crankcase ventilation valve ) Crankcase breather or oil separator .

Literally the only guy who does proper videos on CDI engines , i have a OM646 which is essentially the same engine and i find these very usefull. Very well explained as well thanks man Subbed.
You are welcome ! I am glad that people find them usefull .
Properly eplained. Thank you.
I'm guessing that is Romanian accent? Thanks man.
Great job! Been looking for this information, as got oil leak down that brittle pipe and down the side, will get it stripped, and cleaned, I have got a clk270 2004 with only 58k miles, and loving it!
Keep the good work coming!
I subscribed! Good stuff!
Great video for the oil separator.... I have a CDI and you're a great source for info on CDI's... Thanks alot!!
Glad to help
Very nice
Excellent! Great job? What size do the orings have?
Can you recommend a good oil catch can for a 270 CDI OM612 please?
Maybe do an installation video about one of these.
Thk sir!!
Hi, I have a problem with my Mercedes C220 CDI 1999 and your videos have been quite helpful. In my car the oil separator is dripping oil and water, the car is working perfectly and it does not overheat (the temperature is normal). I would be really thankful if you could point out what the problem could be! Thanks in advance!
you can buy the PCV valve membrane " rubber valve" its on E Bay £11.49 P+P form Poland
Can you give a link for that additional oil catch can. I just took apart mine PCV and the membrane inside has cracks all over it(I noticed it by the oil leaking around the turbo charger from the tube connected to the PCV ). So I'm going to change the tube and the valve itself (the membrane has a little different working here with positive pressure in the membrane itself and so with the cracks it is stuck always open) and I was thinking of installing that additional catch can but can't seem to find any around my area(Bulgaria).
OMG you are my HERO! i just bought w210 e270 and he waste 1/4 of the engine oil and i was desperate, i look up engine and see that the oil separator is swiming in the oil :D, i will do what you done and i will inform you if i fix the problem.
Oh , nice ! I am glad I was helpfull .
@@doit_vehicles ahhh guys it didnt solve the problemm..... i dont know what it could be??
@@r9cheverny433 could be oil in the turbo. take the air intake hose of and look inside ??
@@kennethcroll6972 i will see, but can it be valve guides or how it is called on english, becouse my car doesnt have leaks and he doesnt smoke
@@r9cheverny433 the leak could be inside the turbo on the air intake side. could be a small one that wont make the car smoke. my w210 320cdi hade one
Thanks for the video! I have S204 C220 CDI engine and smoke comes out from where the hose connects to oil air separator. My question is, does that problem cause to the P0087 fuel rail/system pressure too low error code ? Thank you.
Hi, i have a question about a later 2004 MY C220 with 110kw
The separator looks slightly different as it is one piece with the oil filler neck. I was told it should be replaced as a maintenance item and supposedly the rest of the PCV system should be replaced aswell in time. That isnt exactly cheap (90€ VAICO rep.part) so i was wondering if that thing is built like the one in your video which i suppose can be visually inspected and cleaned as necessary, perhaps replacement isnt necessary. I cannot find sufficient info online, only that ignoring these can lead to major engine damage, and as all diesel owners i expect that thing to run for at least a million kms (its a sprinter engine after all isnt it)
I see some oil under the oil pan (oil leak), it is not leaking when the engine is running if I am not mistaken, is that caused by a bad PCV and do I need to replace it? I see a little bit of oil on the PCV
Would you mind to give us the part number for the oil separator and gaskets? I have just buy this car and I realized I must change the whole element including corresponding gaskets ;) Thanks! you were one of the reasons why I decided to go finally for this engine
m.autodoc.co.uk/ I use this online shop when buying most of the parts . The site is available in many European countries . Or search for Oil separator 6110160334 . I wish for you, easy ownership than :)
hello. tell me exactly the serious problem on this membrane.. I have the 220 cdi w203. thank you
In my case, it seems that the middle part of the assembly is the one leaking the oil, not the oil separator that has the membrane, do you happen to know what that part is responsible for?
What is the part number of the two gaskets?
Hello friend, I'm asking for an explanation, it's not this topic, but I need help. I bought a w211, 2.2 with 136 horsepower, restyling, everything is ok, consumption, does not emit clouds of smoke, the engine works excellent, there is no grease around the engine, but after driving, I noticed that the oil was coming out in the place where the dipstick for measuring the oil level was supposed to be, there is a red cap that is not original, and it does not seal tightly and nicely, but I don't think the oil should be coming out there, what a problem is that my friend Is the oil vapor separator broken, clogged...that's why it's leaking, or something more serious?, thank you in advance my friend.
Hi, great video! You mentioned that other oil leak problem can be turbo leak as well. Is that easy fix like changing some turbo gaskets or requires turbo rebuild? I ask because 1 month ago i removed all plastic hoses, intercooler and egr, cleaned them very good from oil because it was leaking outside the plastic hoses as well under the egr valve on a small connection where there is some small sensor all covered in oil and now everything is dirty with oil again like i never cleaned it!
I understand, the oil leak is most likely from the oil separator so installing an oil catch can would have been great after the cleaning . The turbo can leak but it shouldn't be a massive leak
i put a new one , it still smell oil burn on the car if i open window a bit i think the OM611 has the worst oil breather
Thank you for your videos, i have a w210 e220 cdi with almost 500.000 kilometers, it is an old taxi car and i bought it to learn more. Where can i clean carbon deposits and make sure the engine is getting enough air because i feel the car is very slow in 1 and 2 gear, but if you accelerate at maybe 100km/h it is really fast.
HI have you looked at the EGR vavle? they clog up stopping the turbo kicking in. it will be on the air in take side
You have to delete or clean all exhaust line, both cats.
@@Orzoweyes how do you clean the exhaust lines?
@@mbz4652 I used first instance DOT4 brake fluid, then diesel and water without pressure, vertical mode. The result is pretty clean. Be sure you are able to throw those fluids after in the correct sump. Remember take a long hot drive to clean the white smoke after doing it, about 10 miles up to 80 mph.
@@Orzoweyes Thanks for the reply
Oil traveling into the manifold the second is via the turbo?? pleas elaborate on it I have replace my oil seperator but their is still a serious oil leak?
Did you find out?
I can see that the hose in my car is all wet and the oil is going down the pipe (when i unplug the hose i can se oil dripping) . It is leaking quite a bit. Could it be the orings or the valve itself ?!
first double-check the oil level to not be overfilled and then inspect the valve and see if it's clogged, etc ..
@@doit_vehicles i just opened it and i saw that the valve is a bit torn, maybe that is the culprit, but, i saw that there was quite a bit oil on the top of oil separator. Is it always filled that much ?
Can faulty pcv valve cause black smoke on this engine ?
no , black smoke is usually from burning too much fuel
Hello
Where is pcv valve located in Mercedes ml320 model2000?
Thank you
if it's a v6 engine you will find one hose on bank1 and 2 hoses on bank 2 . Located on top of the valve cover
doit_vehicles it’s v6 and if you can support your answer by photo it will be more helpful. Thank you
Hey, i have the same engine on my Benz, some mechanic told me it burns too much fuel because of this separator, is it possible? Runs too rich, or could it be an injector or something?
It's possible that the intake valves are full of carbon build up which is also cause by oil leaks inside the intake . The carbon on the valves will restrict the air flow therefore making the engine to run rich .
@@doit_vehicles i guess i will change the separator and do a intake clean up then, i appreciate the answer very much, have a nice day :)
@@AreskCSGO I hope u will fix the issue , Cheers !
@@doit_vehicles i cleaned the air flow sensor and i will change the oil separator this days, a lot of oil in there :) thank you for the tutorials
@@AreskCSGO does you inspect oil stick? Becouse when i bought my e270 oil was on the max but after 3 days it is go low like he waste 1/4 of oil, and my searator and hose are full of oil :D
I had an catch can installed on a om611 and never catch any oil, I don t recommand it
What was the cause of the can not catching any oil? Was the can good installed or is it in general not a good idea to install a catch can on this engine?
@@mbz4652 no idea
