Valve Oil Leak

Valve oils are essential for lubrication as well as combustion purposes in an engine. Due to too much heat and pressure, there is damage to the valve cover. This results in leakage of 1M valve oils. 

Fuel Leak

A fuel leak is also very common in the 1M engines particularly when the car gets older. This happens due to the breakage of valves or pistons also in some cases. In addition, some parts of the engine can break too, due to which fuel leakage happens. 

Oxygen sensor problem
