Can I do this myself?
The installation process is different for each car, and while some are relatively easy for the average DIY owner, others require some special tools and basic understanding of cam timing and TDC (Top Dead Center). We provide specialized documentation for the single and dual vanos installation as well as tool rental. Both of these engines are very straight forward to work on and the installation can be done by the average DIY owner.
The Euro E36 M3, E39 M5 and E46 M3 vanos units are somewhat more difficult to install and may require specialized tools. A professional BMW tech who is familiar with the vanos removal/installation process is recommended for the procedure.

Installing the single vanos is a straight forward procedure, but does require a few specialized tools to maintain the proper timing between the crank shaft and the cams. Installing the single vanos without using the locking tools may result in poor performance or a 'Stuck Vanos' code.
The Dual Vanos installation (E46, E39 6-cylinder) is also a very basic procedure that can be done by the average mechanic, and is not any more difficult than the Stage I single vanos installation. The cam gears and timing chains do not need to be removed, so there is no possibility of accidentally affecting the cam timing, and the BMW tools are not needed for the dual vanos installation.
The Euro E36 M3 and MZ3 vanos units are quite different from the US spec single and dual vanos units, and are somewhat more difficult to install. The same basic principles apply, but they can require specialized tools to install the vanos correctly and to ensure that the cam timing is properly set. Please visit our Euro vanos page for more details.
We do not offer specialized documentation for the Euro kits at this time, but you can download the BMW documentation (taken from the TIS CD) from the left side bar.
The E39 M5 vanos installation is moderately difficult and quite time consuming since you are dealing with 2 vanos units, while also making sure the cam timing is correct for both the left and right banks. A skilled BMW technician is recommended for this procedure in most cases. Please visit our M5 vanos page for more details
The E46 M3 vanos is reasonably easy to remove and can be done without special tools. Please visit our E46 M3 vanos page for more details.
We do not offer specialized documentation for the E46 M3 vanos at this time, but you can download the BMW documentation (taken from the TIS CD) from the left side bar.
