BMW S50B30 VANOS adjuster unit solenoid valve seal kit - Upgrade kit

We offer a complete seal kit / repair kit for the VANOS adjuster unit solenoid valves in S50B30 engines used in BMW 3 series models. 


BMW models with S50B30, S50B32 and S62 engines will start leaking oil from the solenoid valves once the original seals wear out to a point that they are not able to withstand the high pressure inside the VANOS adjuster unit anymore. The grooves of the solenoid valves are uniquely shaped in a way that makes them not suited for the use of o-rings. Therefore we developed special u-shaped seals made out of heat and wear resistant Viton® (temperature range from -20°C/-4°F to +204°C/+400°F). The seals are CNC-milled to our specifications within tolerance class DIN ISO 2768-1-f (fine) in Germany to ensure a high level of accuracy.

Here you have the opportunity to purchase these 4 seals (2 small seals, BMW reference number 11 36 7 830 828, 2 large seals, BMW reference number 11 36 7 830 829).


Attention: The solenoid valve seals are a very tight fit. Before installing this type of seal, the entire surface of the seal and the VANOS adjuster unit housing must be covered with a thin layer of engine oil.
