MOPED - VALVES & VALVE STEM GASKET

Despite their high reliability and long service life, moped valve stem seals are wear parts. In particular, high temperatures, strong mechanical stress and chemicals can clog the moped valve stem seal and a reliable seal is no longer guaranteed. Symptoms of a defective valve stem seal can include extremely high oil consumption, excessive exhaust smoke as well as blue exhaust gases during cold starts. However, there may also be another defect on your moped. However, you should not wait too long before replacing the valve stem seal, as oil carbon can build up on the valves over time, which can lead to further engine problems.
