Main Factors That Cause an Engine Oil Pan to Leak

An oil pan consists of a dark-colored part in which oil is stored. An oil pan’s primary function is to transfer the oil to the parts in the car and after lubricating them, the remaining oil returns to the oil pan and continues until the oil pan is empty. The purpose of lubricating is to reduce friction and increase efficiency will make the parts run in an organized and smooth way.

The gasket covers the oil pan which results in making oil contained. An oil pan also prevents the oil to be leaked while lubricating the parts. The main thing which may result in leaking the oil pan is the material by which it is made.

Temperature Difference

One of the common reasons for oil pan leaking is the change in the temperature. The car remains cold when the engine stops working and gets hotter when the engine is in motion and is doing work. This reason helps the metal parts to expand and contract which may result in a hole in the oil pan which cause leakage.

Untightened Bolts

The importance of bolts is very important in an oil pan. As if any bolt from any area gets loss or is to tighten properly then the oil pan is unable to close completely and the oil leaks from different portions. The reason of loosen the bolt in the changed temperature at different intervals.

Bad Gasket

The oil pan gasket is a part of the engine oil pan. With time things wear down so the same case with the oil pan gasket it also wears down and starts leaking along the sides. It sometimes feels like the engine oil pan is leaking because the oil collects around the gasket. The leakage of oil due to the gasket can be prevented by using cork gaskets.

Contact Points
