vanos valve repair

hello im new to this forum i would like to ask a few questions regarding the vanos valve. i have a 2005 z4 with approx 79,000 miles. i have noticed that the car is not as quick as when i first purchased it 3years ago. i was thinking about repairing the vanos o-rings as precautionary now my main question is on this perticular model do i have to set the timing? and do i have to lock down the cams? i have noticed on you tube that they just pull the valve out. is it this straight forward ? thanks
best regards Manuel

There is a section dedicated to your car, move your question there. This section is for E89 Z4, starting with MY 2009.

Rebuilding the Vanos (O rings) requires removal of the valve cover. If you replace the seals and all associated geaskets yourself it is about a 4-6 hour job @ about $120 in parts or you can buy a rebuild Vanos assy & associated gaskets @ $1500. I've done this on my wifes' & son's 3 series E46 with M54 powerplants. Here's a couple of links that have some great infor. Might as well replace the plugs while you have the top end opened up and upper the O2 sensors as well.
