For the past Month I've been having an oil leak on the passenger side of the engine, at first I thought it was the valve cover gasket so I changed it like two weeks ago and the oil leak still, finally today I spent the whole day trying to figure out where is the oil coming from.....so I cleaned everything good so I would see from where is the oil coming from....
finally I found it... is where item #8 http://www.realoem.com/bmw/showparts...73&hg=11&fg=50which is the shut off valve connects with item#7 which is the hose that goes to the air pump, now Im wondering ....is there suppose to be oil coming from the shut off valve I thought only air or gases where suppose to travel through there is this normal or do I have a bigger problem in my hands...please advice if you had this problem before
never heard of this before... I too would not expect oil in that line, only secondary air itno the heads.
I had an oil leak when the dealer failed to replace the rubber grommets under each valve cover BOLT. 8 months after they did the gasket they redid it but replaced the grommets.
Ok, so after some more digging through the engine bay I narrowed it down to the vanos, which in fact is leaking through the vanos solenoid.... on top of the shut-off valve...
so I 've been doing some reading on how to fix this leak and it looks like a simple change of O-rings but I dont know how to do it....do I remove the circuit board and look for the rings or do I remove each solenoid? here are some pics of the vanos solenoid part...can somebody explain exactly how to do this? http://www.realoem.com/bmw/showparts...74&hg=11&fg=15
I know it looks clean but there was oil in there when I took the cover off....
also, I dont have any vanos codes so I know this part is in working condition it just leaking oil....
Ok, so since nobody seemed to know on how to remove I continue with my project on my oil leak...so I removed the vanos solenoid circuit board with the solenoids its pretty simple just wiggle them a little bit and they will start to come off....but one at a time little by little until the whole board comes out....
Once I had it out my suspicions were correct one of the O-rings wasn't 100% pics below....now to wait for the dealer to get those O-rings, I ordered them today they should be getting them in a couple of days....
I will update when Im finish, I just wanted to share with everybody just in case somebody goes through the same problem
Excellent info. Reading this made me wonder...if you took this to a franchise dealer would they do the same fix or would they say you need a whole new vanos system?
