Solving the Problem of Oil Spitting Out of Your Oil Cap

AvatarByCarl Frisch

Oil spitting out of the oil cap is an issue that can arise in vehicles that use engine lubricating oil. This problem occurs when the oil level in the engine is too high and causes the pressure inside to build, resulting in oil being forced out of the oil fill cap. The issue can be caused by several factors, such as overfilling during an oil change, a faulty or blocked breather valve, or a failing seal on the oil cap. The presence of excessive engine heat can also lead to this problem. If not addressed promptly, this issue can lead to more serious damage and failure in engine components. To avoid this problem, it is important to follow manufacturer’s instructions for checking and topping off the engine oil level and replace any faulty components as soon as possible if required.
