Valve Cover Gasket Located at the top of the engine, the valve cover gasket creates a barrier between the cylinder head and the valve cover. Common Sealing Points and Gaskets The majority of engine oil leaks originate from worn or improperly installed sealing points designed to keep the oil contained within the engine block and timing cover.

When this rubber or cork gasket hardens or cracks, oil seeps out along the seam, often running down the front or back of the engine and dripping onto the ground below. Identifying the source of an engine oil leak quickly is the most critical step in preventing severe and expensive mechanical damage.
This usually occurs because the gasket was not properly lubricated before installation, the filter was not tightened sufficiently, or the rubber gasket from the previous filter was left behind on the mounting surface, creating a double seal that distorts the new gasket. Mechanics often clean the entire engine bay with a degreaser and then run the engine for a short period while observing the fresh flow of oil.

Oil Drain Plug The oil drain plug is a straightforward component, yet it is a common source of leaks due to human error or wear. If the washer is damaged, the bolt is over-tightened causing the threads to warp, or the plug itself is stripped, oil will drip steadily from the lowest point of the oil pan.
