Engine valve cover gasket for Peugeot and citron 
In a perfect world, an engine would remain clean and free of leaks, for an indefinite period of time. However, the notion of such is little more than wishful thinking. With age, and ample mileage, every engine becomes susceptible to pesky leaks which can lead to a number of aggravating issues.

Leaks of this nature can originate from multiple sources, often varying significantly in severity. The most common of these leaks allow warm engine oil to escape from an engine’s block and cylinder heads, coating the exterior of the affected engine in the process. 

Perhaps the most common of engine oil leaks, are those that originate from an engine’s valve cover(s). In fact, the vast majority of moderately aged engines will exhibit some degree of valve cover-related oil leakage, leaving an untold number of motorists to contemplate the repair of such issues on an annual basis.

Read on to learn more about the specific duties of an engine’s valve cover gasket, as well as the root cause of valve cover leakage.
