Purchase VAC - Professional VANOS Repair & Modification (Single VANOS) M50 & M52 / S50 & S52 US

Many BMW owners are faced with VANOS issues in their high mileage engines. These problems can make your smooth running BMW sound like a noisy diesel and rob you of low and mid RPM torque so crucial for good performance.

So What is VANOS?
BMWs acronym for Variable Valve Timing, a technology that lets engines produce more power and efficiency over a wider RPM range. A brief description would be to say that this technology enables an engine to have excellent street manners (creating power in lower RPMs) and also make power in the high RPM band (Aggressive, sports & track driving)

What do you offer?
For years we have offered professional grade VANOS repair and modification for daily-driver local customers and professional race teams, but now our services are also available to you, for repair and upgrades to your VANOS assembly.

Our VANOS units are repaired and upgraded to our high standards of quality (The best in the industry). With years in the BMW repair business and 40+ in high performance machine shop & racing world, you are assured our VANOS units are made to the tightest tolerances and with the finest components available.

What makes your repaired VANOS units the best?
In our in-house state of the art machine shop facility, the same where our world class engines are built; each unit is cleaned, fully checked, and refreshed using the best long-life components available, we don't settle for the equivalent brands that quickly deteriorate, but high quality Viton o-rings and long life seals throughout the assembly.

Our units are repaired on computer controlled machine equipment not available to 'home-brew' companies and are rare even in many other professional machine shops.
Internal oil flow and pressure is optimized for durability and quiet operation. We also modify the thrust-washers on the cam assembly and utilize the late style dual spring/hydraulic tensioner for improved functionality.

Our units surpass OEM and other repairers units by far and outlast them as well, and the efficiency of our machine process allows us to offer them all for a better price!
VAC repaired VANOS units are 100% rebuilt and checked, not just an in and out repair of the individual failed component like many others.

What Options should I select?
Repaired: for customers with aging or malfunctioning VANOS units. These are to be used along with factory BMW's OE cams, VAC Sport cams, or Schrick's 264/256 Sport cam set.

Modified: These units are intended for use with Sunbelt/ Bimmerworld / VAC Track & Race Cam sets. For these high lift cams, this limits the travel of the VANOS mechanism, allowing these camshafts to be used with OEM pistons.
Those fitted with our CP pistons can use Repaired as we have larger valve reliefs in our pistons.

VAC Tech Note: Our VANOS elimination kit is for a race vehicle that does not see low RPM use. If you have a full race vehicle, this is a good choice but if you drive your BMW on the street; we highly recommend keeping your VANOS system as it provides a significant improvement in low RPM torque.

For the Bimmerworld /Sunbelt Track Cams and our VAC Track Cams, it is highly recommended that you select the RACE CAM option when ordering if your installing these into an engine with standard size pistons.
This allows quick and easy installation for anyone using race cams, limiting travel to assure reliability and provides the safety margin necessary when the VANOS is at full advance. This modification is NOT required or beneficial when using OEM or Schrick camshafts.
