What are the effects of oil leakage from the BMW valve cover gasket?

[LeAaron]

BMW valve cover gasket oil leakage has the following effects: 1. Aging and brittleness of the valve cover gasket: Loss of sealing ability leading to oil leakage, which can be resolved by opening the valve cover and replacing the gasket; 2. Oil seepage: Blockage of the PCV valve in the crankcase ventilation system causes excessive internal pressure, ultimately resulting in oil seepage under pressure. Below is more information about the valve chamber: 1. Introduction: In the engine structure, the cavity space where the valve ends are located is called the valve chamber. In typical automotive engine designs, the valve ends are connected to the camshaft via lifters or pushrods; the camshaft controls valve movement, with modern engines often positioning the camshaft above the cylinder head. 2. Structure: The valve chamber is covered by a camshaft cover, forming a nearly enclosed cavity with the cylinder head (also connected to other cavities via oil passages such as return and supply channels). The engine valve cover is simply referred to as the valve chamber cover.
