What is a Small Oil Pan?

[EmmanuelAnn]

Oil pan is the lower half of the crankcase, also known as the lower crankcase. Functions of the crankcase: The crankcase is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. It also prevents engine oil from deteriorating and avoids leakage from crankshaft oil seals and crankcase gaskets. Introduction to the crankcase: The crankcase ventilation check valve is installed on the valve cover. Depending on different engine operating conditions, it automatically controls the recirculation amount of blow-by gases in the crankcase by utilizing changes in intake manifold vacuum. If the crankcase ventilation check valve is damaged, it can cause increased pressure inside the crankcase, accelerated oil consumption, and affect exhaust emissions.
