I run ethanol free and have 0 mayo

Hello Guys,
Thank you for sharing, my M54 2001 E39 has been burning oil for years, power is still good though, I have changed the CCV 3 years ago but the oil consumption has been going up the last 1 year & now at the rate of 1L/500miles, I have finally decided to join the group & install a OCT.

What I did:
1. connect the hose from VC to OCT
2. Hose from OCT to PCV then to IM
3. plug the oil drain cap

I have been using 10W40 semi syn oil and after the OCT installed, I plan to use 5W50 fully syn oil.

Took me a few days to get done as I can only do it at night and due to problem sourcing for connectors and hoses.
Last night when I finally done and start the car, it run like crap for a few minutes as if it was running on 5 cylinders and engine died once (it was norm whenever I left it for a few days), what is the possible problem? anyway it was fine after it reach norm temperature.

I also discover that while the car is running, it was difficult to open the oil filing cap as the vacuum is sucking the cap, could that be the case of too much vacuum?, can too much vacuum damage the engine? BTW I used a 1 way valve which is normally use for brake application as PCV.

You need to use a PVC Valve--not a one way valve--I used a PVC for an old Ford 6 cylinder engine on mine--there are others you can use though--the way yours is set up now--you have too much vacuum being pulled and it's not controlled--you will still have the same amount of vacuum though after using the PVC --but it will be incrementally pulled from the carnckcase--that's what the PCV will do

Hello Poolman,
Based on your advice, i have bought the Mercedes Benz A 2710180029 Air Pump Check Valve M271, please refer:
http://www.everythingbenz.com/z/part...mp-check-valve
the valve has spring and plunger inside, I assume this is what you call a PCV?

what did you reduce your hoses to? too many clamps and cuts for it not to be a giveaway

I checked the pcv I just bought...it takes a little more pressure to blow through as compared to the 1 way valve i installed yesterday.. I have now installed the pcv, same strong vacuum at the oil fill cap, reading through the previous discussion again, such strong vacuum is normal, so I m going to test the car at a distance tonight.

Finally tested the car, felt more power & faster response, I will update on oil consumption in a week time.

Now, i see it!...how my car burn oil, drove in 42C today, when I stop at the traffic light, notice smoke coming out from my car, took it aside and discover the hose from OCT to IM has crumple due to heat and vacuum and oil is blowing out from the valve cover due to pressure, I know this has been mentioned b4 but as i cannot find the 5/8" fuel hose, I used the gas hose.. big mistake, I release the pressure and took the car home, temporary replace with 3/8" fuel hose that I kept, all seems fine now but now i have to change the valve cover gasket next.
