See attached pictures. I did not measure vacuum after the mod yet. The crankcase remains under vacuum for some time after the engine shut off - i don't see any issues with that.

axgordon, thanks for the pics, they look great. Since that PCV needs to be vertical, call me stupid but could you not put it vertical facing downward and use a 90 degree elbow with hose to eliminate the "hose loop" on the upward facing PCV?

Conceptually, this is similar to E23 (1983-1987 735i) with simply a hose slating upward as the CCV, talking about simplicity.

Two things come to mind...
1. For those who want to sell the car in the future, the next owner will likely has some questions for all these "snakes" running around on top of the engine. You will need to explain it to him/her. 2. The E23 (1983-1987 735i) Intake Manifold sits ABOVE the engine. So the CCV system in that car is simply a tube going upward, see photo for #11 in E23:

axgordon, interested now to hear about the shop owner's opinion on the piston rings. He believed that replacing piston rings on stock CCV setup on M54 would solve oil consumption in higher mileage vehicles? Or alternatively you could keep the low tension piston rings and do the "CCV Bypass/PCV install" like you have done and solve the same issue?
You are correct I just rolled 80k miles a week ago so I'm not as "up there" yet.

trader4,
I am talking about brand-new stock system from showroom. From an engineering standpoint, E23 is more simple than M52/M54 setup. 1. In the E23, the mixture of oil and vapor goes up the slope (the simple tube). Vapor keeps going up while oil, being heavier, drips back down the valve cover area. 2. In the E53 M54 setup, the Intake Manifold sits LOWER than the valve cover. So the mixture of oil + vapor goes DOWN the slope and pools at the Separator area. In theory, oil being heavier goes down the dipstick housing and vapor gets sucked into the Intake manifold. However, when the membrane opens up (under certain vacuum condition), some oil gets sucked into the I.M.

let me clarify this - the oil consumption was corrected by replacing worn out piston rings with a new set of the stock rings from the dealer. The shop owner stated that old rings were worn out and did not seal / removed oil correctly. I did not experiment or have an answer on possible re-positioning of PCV valve. Personally I am totally OK with the loop... for now

No worries, I imagine worn out rings would cause consumption, but is not the rule across the M54 nor is it something I've read that is something that is done often (replacement of piston rings)
If you guys want a real, OEM solution to delete the CCV, using all OEM parts, perhaps the E46Fanatics guys will tickle your fancy: (M56 Valve Cover with integrated oil separator, VCG, oil fill cap gasket, and breather hose is all thats needed), the M56 VC fits on the M54 with no issues. The Permanent M54 CCV Delete - E46Fanatics
