If you drive a BMW 6 cylinder vehicle 1993-2006 your Vanos (variable valve timing unit) is most likely failing. The O-rings fitted to the pistons within the Vanos unit wear prematurely because they are constructed of poor quality Buna rubber which is not suited to the elevated temperatures of their location. The seals fail and lead to Vanos unit failure. BMW do not provide replacement seals, they do provide complete Vanos units at vast expense but these again are fitted with the same poor quality seals that will fail again.
It is also common for the Vanos unit to develop a rattle which can often be heard within the vehicles cabin. This rattle is caused by wear in the variable valve timing gears. This wear allows axial play and causes components to rattle. Removing the Vanos pistons axial play reduces this rattle significantly.
By installing our improved design Viton seals and PTFE rings you will restore your Vanos unit to full health. Our seals are specifically designed for the environment in which they are fitted, well suited to the vast temperature range of the Vanos unit, constructed from improved materials designed to last. Our seals and piston rings have undergone extensive testing and will not deteriorate over time like the OEM part, designed to last the lifetime of your vehicle. Our product will restore your Vanos unit resolving the common symptoms which occur with failure noted above.
Our vanos piston rattle rings remove the axial play in the pistons reducing engine rattle sounds and wear.
