Great video, best so far on Catch can install on this engine. I will go mine like yours. The catch can, you can insert inside a coarse steel wool to catch any dirt. Makes a good filter. Thanks for the excellent video step by step and straight fwd tutorial. Always love your video production. Bright lights and no music. easy peasy....
Thanks for the kind words . Had the steel wool idea in mind when installing the catch can, but want to see how much oil is accumulated in the can before putting the wool in.
Great video. The leaks on the oil cooler in this motor, the M272, is a common issue. It would be great if you make a video about the change of the gasket or a solution for this. Thanks!
Recently I’ve had the problem with oil suction into the intake and would also rather think about something you’ve done. Everything was much easier: I changed 2 intake gaskets before the throttle body and since then everything works fine. Old gaskets let some air in and changed the proper vacuum in the motor ventilation. Now there is no oil consumption anymore
Never thought of this solution before. I thought I was the only one replacing the manifold only to have it throw a code again 1 year later 🥲 I did have the separator leaking on one side so I fixed it. However you are right, I still see oil stains on the throttle side so this might actually be a great solution before replacing the manifold again. I think you did OE separator to catch can to manifold. Is this better than other configuration or is it just random? Also did you notice any performance issues ?
I had your same issues, even after replacing the factory pcv still getting the codes. The car is on its 3rd manifold and might need a 4th soon without the catch can. I did clean the throttle and used an intake cleaner spray after installing the catch can and haven't had the codes ever since. I will still use the intake cleaner spray with every oil change to clean all the old oil deposits from before the catch can to extend the life of the current manifold. Yes, I did OE separator to catch can to manifold like you said. Did it that way since it was the easiest way I saw and don't want to delete the factory system, plus its reversable if I ever wanted to go back with no catch can. No performance issues other than not seeing the check engine lights again.
@@ZakiGarage I am having a code 0521 - The charge movement flap (cylinder bank 1) has a malfunction. I will clean it but I wouldn't be surprised if I still had to replace it and add the catch can to avoid this happening again. Beloved E class never fails to keep the suspense. (Edit: No check engine light and the code has been there for the last 1 / 1.5 years at least)
@@walidmorsi7156 if its the charge movement flap I'm guessing ether you have a bad vacuum line controlling the flab (I'm assuming its controlled by vacuum lines) or the most likely you'll need a new manifold. Better not to leave it like that for long, don't want the flaps to break off and go into the engine and destroy it, I think I read about that somewhere. And if going to do the manifold do recommend changing the oil separators and all the intake vacuum lines along with the catch can to prolong its life like you said.
Good question but I wouldn't know the answer to. I would guess using the filter and venting to atmosphere on modren engines would create a vacuum leak that would cause idle issues.
Had it installed since the factory oil separator system lets lots of oil into the intake manifold. With time it causes engine issues and replacing the manifold costs thousands $$.
Great video I just installed mine as well on the m273 and its been a few months and there is nothing in the catch can is this normal? I was nervous there may be an obstruction? Would I get a check engine light if there was an obstruction in the catch can or any of the hoses? Also does it matter which side you use for in or out? Mine was not labeled but I think the side with the filter is my inlet.
Mine also is very slow in gathering oil, its been 6 months for me and still just a small amount of oil gathered. But the most important thing is no more oil on the throttle body and into the manifold and smooth engine. Sprayed an intake cleaner with the engine running with this instillation, engine has never been smother for me. I also had concerns like you but I wouldn't think there is an obstruction. The In\out direction could be a reason but I'm also suspecting the length of the hose. I'm wondering if oil condenses in the lines and returns to the oil seperator before it gets to the can.
@@ZakiGarage this was my concern mainly as well that oil went back to the engine. In fact I notice a small wet spot on the bottom bolt area of the crankcase vent that I installed new at the same time as this catch can.
The PCV system on this engine is supposed to separate oil from going back into the intake manifold. Unfortunately, the PCV doesn't separate the oil well and lets oil into the intake manifold. Over time oil deposits in the manifold will make it fail eventually. The catch can is to prevent the oil from going into intake manifold.
Its a Catch Can, there are many vids that explain how it works. But it prevents oil getting into the intake manifold from the PCV sys. The oil getting into the manifold will cause engine issues.
