M54 leaks oil!

Lots of things have been done during last year, but it still fckn leaks.

If I missed something? Possible.
If I used bad gasket on something? Possible. If I used good gasket and installed it in wrong way? Possible.

What is there in M54 which can leak oil?
At this point I don't care about burning oil in cylinders, but I want to stop leaving marks on parking lots.

What can leak motor oil in M54? All other fluids stay, that one doesn't.

It doesn't leak while parked. If I went high revs then there are visible drops leading to my car. Something in the upper part of engine?

What gaskets have you replaced? Valve cover, OFHG, oil pan?

Try putting some fresh cardboard under the car as soon as you park it. You may be able to tell the approximate area where the leak originates, just remember that leaks will often travel....

Already changed valve cover gasket, oil filter housing gasket, oil pan gasket, crank case ventilation/oil separator, and crank shaft gasket.

I would think it's something on intake manifold side, according where oil drops appear first, but it's hard to be sure because those bottom panels can collect some oil and lead into some direction.

Did you check the Vanos oil feed line hoses? Maybe the PS fluid is leaking and not oil?

Powersteering pump and hose I changed, and power steering fluid level stay now, motor oil is reducing. Vanos feed lines might be something to look at yes..

+1 on the Vanos line. Mine was starting to leak. Replaced it with one of these. Good luck...

Only leaking while driving, I would vote for VCG or the VANOS oil hose.

This ^^^^^^ is probably on the right track. VCGs (especially the Victor Reinz ones) often get pinched in spots, leading to leaks..... Both of the above-mentioned areas should be on your "Usual Suspects" list

M54 leaks oil!

Sounds like youve taken care of the usual suspects. Maybe the valve cover itself is cracked or warped or something went sideways during the install process.
Id degrease the engine from top to bottom, drive it for a day or so, have a look see to narrow down the source of the leak. There might even be dies that you can add to the oil to help with the process.

Might be I took care of some things, but basically I'm thinking of redoing everything, unless can think of something I didn't try yet.

I had to do the valve cover gasket a second time because of the pinching as FastBob mentioned with new gasket. Do you smell oil burning in the car with the heater running? A typical indicator.

There should be a slight vacuum in the crankcase at idle, if there is pressure, that can provoke leaks at the engine seals and gaskets.

Ok, right now I'm preparing to take intake manifold off for seeing better what's going on there. Preparing to redo oil filter housing gasket and CCV. Ordering what's needed..

Which one of those disa valve rebuild kits is good?

I see few in ebay, but they are obviously not same.

I did the rebuild kit from German Auto Solution where they have a metal screw/bolt to replace that plastic screw and also a better o-ring.

I agree with the German Auto Solutions DISA repair kit. That is the kit I used and it is very high quality, and easy to install.

Before installing the repair kit, make sure the DISA you have has a good diaphragm in the actuator and that there are no large missing chunks from the valve seat.

There is an air bleed hole on the control solenoid of the DISA assembly. Stroke the actuator diaphragm all the way to the valve closed position and hold your finger tight against the bleed hole to block any air from flowing through the hole, then release the actuator diaphragm. The actuator diaphragm and connecting rod should move toward the valve open position only a small amount and stay at that position without moving any further. The diaphragm will only return to the valve fully open position when your finger is removed from the bleed hole. If the actuator connecting rod and diaphragm slowly or quickly move all the way back to the valve open position while blocking the bleed hole, the actuator diaphragm is leaking and that DISA assembly cannot be repaired.
