    This review comes late as we rebuilt the Single Vanos (95 M3) in the Winter of 2010-2011 as the vehicle sleeps in the garage. The purchase was made online, it came within a week, well contained and protected. All the parts were labeled. DIY directions printable from the net. Accessory/Adjunctive tools available to purchase also to ease the rebuild from the site. It was a little stressful doing it for the first time. Car had 94K on it. Not much of a gurgle gurgle. Gas mileage 22.2 MPJ before, 24.3 after with major tune up of other parts.

    PRO's: Excellent quality of materials, both the O rings, telfon ring, and the bearing. Better than OEM. The most METICULOUS, EASY TO READ directions, one could imagine. He/She(ROJ??) left nothing to the imagination or guess.

    CON's: Not many....You need some time, if you are not a mechanic like me. You need a bench vise and a bench....Took us about 8 hours, but we did not want to rush it. You need a 1/4" torque wrench for accuracy...With all the parts and accessory tools, you are probably looking at $200 for everything. You could get a rebuilt or new Vanos unit for more and save you time if you did not want to perform this yourself.

    Overall: 4.5 out of 5 stars..This was a very good experience. Did it with a friend would had more skills than I. The directions will not let you fail. Smooth smooth mid torque response now and increase in gas mileage. Would recommend performing valve cover gasket, plugs, ignition coils, crankshaft and camshaft sensor if you have the time and money.
