M156 Valve Buckets

The Weistec Mercedes SLS Valve Buckets are engineered as a direct replacement for the M156 engine's stock valve buckets, addressing a known issue of accelerated valvetrain wear caused by repeated contact between soft and hard metals. These M159-design buckets are crucial for preventing premature wear, degrading engine performance, and potential engine failure. These valve buckets are designed to combat "bleed down," a common problem in M156 engines that leads to excessive valve lash, especially during cold starts. This condition is often audible as a loud tapping noise until the engine reaches operating temperature. The M159 valve buckets feature an advanced anti-friction coating to minimize wear on camshaft lobes and an improved hydraulic system that eliminates "bleed down." Installing these components ensures a quieter engine on cold starts and protects the valvetrain from accelerated wear. Key features include an anti-friction coating, an improved hydraulic system, and they are genuine Mercedes-Benz valve buckets. They are a direct replacement for M156 valve buckets, simplifying installation. The product comes with a CALIFORNIA WARNING regarding Cancer and Reproductive Harm.
