Aluminum Valve Cover Upgrade - M52 S52

Product Details

BMW's Single-VANOS M52 and S52 engines were equipped with plastic valve covers from the factory. Nearing thirty years post-production, this material choice has proven to be problematic. Due to years of exposure to extreme engine temperatures and chemical-rich engine oil, these plastic valve covers will eventually warp. This results in a valve cover that will not seal, requiring a complete replacement of both the plastic valve cover and associated gaskets. 

To remedy this, many enthusiasts opt to swap for the magnesium valve cover found on M50 and S50 engines. Unfortunately, magnesium is no less resistant to heat-induced warpage than plastic. 

Thankfully, Bremmen Parts is aware of these issues and has created an exact-fit, high-quality performance replacement for all Single-VANOS M52 and S52-equipped BMWs. This cover features durable aluminum construction, which eliminates the warping issue found on OE plastic and magnesium valve covers. Unlike the OE magnesium cover upgrade, Bremmen's aluminum cover retains the forward oil fill location found, allowing you to retain your existing engine beauty cover. 

Whether you're replacing a warping plastic cover or preemptively replacing this failure-prone component, Bremmen has you covered with a direct-fit aluminum valve cover upgrade.
