Professional Rebuild ServiceDrVanos is the original vanos repair source having rebuilt and repaired over 1000 vanos units with excellent results since we opened our doors in 2007. We are the only vanos repair source that offers a complete vanos solution for the Euro 3.0l and 3.2l E36 M3. While you may find some imitators selling a few small parts that are commonly available through the dealer, DrVanos is the only company offering custom designed high quality seals and O-rings to address ALL vanos related problems. Our professionally rebuilt units are complete with specially designed intake and exhaust piston rod seals to replace the factory seals. These specialized piston cannot be purchased through BMW. Our rebuild service also includes modified gears to cure the infamous 'diesel rattle' noises, something generic kits cannot offer. Without all of our unique upgrades your vanos repair is incomplete, so don't be fooled by 'off-the-shelf' rebuild kits consisting of a few factory bolts and gaskets.
What we doDrVanos offers their rebuild service for the 1993 - 1999 Euro E36 M3 - 3.0l (S50b30) and M3/MZ3 3.2l (S50b32) vanos units.The Euro M3 Vanos is well known for having problems with the main intake and exhaust piston seals, as well as solenoid O-rings failing causing various problems such as poor performance, hesitation, or rough idle. There are no less than 19 seals and O-rings within the Euro 3.2l vanos which are all made from a material not well suited to the heat of the engine. We have addressed these shortcomings by replacing ALL of these seals and O-rings with high quality, custom made Viton or Teflon parts. This material is much more suited to the harsh environment and high temperatures seen in the vanos, and will easily last the life of the engine.
What's that noise?The common 'diesel rattle' that is heard on the Euro 3.2 and 3.0 vanos units can be attributed to the splined gears that fit at the back of the vanos. Each splined gear has a bearing assembly inside which allows it to spin freely with the camshaft. These bearing assemblies are designed with a very loose tolerance from the manufacturer causing them to rattle or resonate at certain RPM's. At DrVanos we modify these bearings to bring the tolerances much closer together for a tighter fit, eliminating the dreaded vanos rattle for good.
What else?Also included in the rebuild service are new gaskets, filter, and upgraded oil pump retaining ring. The oil pump is also rebuilt and the solenoids are pressure tested using the factory BMW solenoid test box to ensure everything is working properly before shipping the vanos to you.
