At DrVanos.com we have addressed all the well known problems related to the U.S single vanos engines and provided solutions to those problems in a complete, ready to install kit. Each vanos is fully rebuilt using modified bearings to eliminate the dreaded rattling noises, then high-performance Teflon seals and Viton O-rings are installed to restore lost power and increase the life of the unit. Our vanos units will stand up to more abuse making them ideal for street/track cars, race cars, and forced induction applications.


The Single Vanos comes as a fully rebuilt vanos unit with modified bearings to eliminate the dreaded 'Vanos Rattle'. Every vanos also comes with new high-performance Viton O-rings and Teflon seals installed to restore lost power and improve gas mileage... two solutions in one package!

The Stage I Vanos price includes a fully refundable $100 deposit. You can return your old vanos to us using the supplied UPS return label in the box and we will refund your $100 deposit to you within 1-2 business days for a net price of $275.

The Stage II kit adds REM coated cam gears and thrust washers which will further reduce chain noise and cut down on friction, allowing the vanos to work with less effort. This is a great upgrade for any car that sees more than the typical daily commute, and will stand up to the abuses of Auto-x and Club Racing or Forced Induction applications.

If you are using high profile race cams, such as the Sunbelt cams, then we can add a shim to limit vanos travel adding a margin of safety to the valves at very high RPM's. We offer a standard (Small) shim for mild race cams and a thicker (Large) shim for more aggressive cams. The limiter is NOT recommended for stock cam profiles as it will reduce overall torque at lower RPM's.

We have made it even easier to return your core to us! All Vanos units come with a pre-paid UPS return shipping label included in the box. Simply use the provided zip-loc bag for the vanos, place the included shipping label over the original label and drop it off at your local UPS Store. *US Customers Only*
We have created specialized installation documents for the Stage I and Stage II kits and offer tool kit rental as well. You can download the installation documents from the menu at the left. Instructions are in PDF format.
Tool kit rental is available with the purchase of a Stage I or Stage II kit, and includes the cam alignment blocks, crank locking pin and gear turning wrench. The rental cost is $25, plus a $75 deposit.

The core charge allows us to send you a rebuilt vanos at a much lower price than a new unit would cost from the dealer. By sending out a complete, ready to install vanos the customer has the ability to replace their vanos as quickly as possible and then return their old vanos for the core refund. This helps to keep your downtime to a minimum so you can get back on the road without waiting for parts.

The Stage I core charge is $100 (Vanos Only)
The Stage II core charge is $200 (Vanos, 3 Cam Gears and 2 Thrust Washers)

We ask that you return your old vanos unit to us as quickly as possible. Once we receive your complete core we will immediately refund the full core charge amount back to your Paypal or credit card account.
