Engine Oil Leaks: Causes and How to Fix Them

Engine oil leaks can be a frustrating problem, but finding the source of the leak is the first step in fixing it. One way to detect oil leaks is by inspecting the engine bay for oil stains or puddles underneath the vehicle. Another way is to check the oil level regularly and monitor any sudden drops. You can also use a UV dye tracer that can be added to the engine oil to help pinpoint the leak source under ultraviolet light. 

Causes of Oil Leaks

Engine oil leaks are a common issue that can affect any vehicle, regardless of its make or model. If left unaddressed, oil leaks can cause serious damage to the engine and result in costly repairs. In this section, we will explore some of the most common causes of oil leaks in engines.

Damaged Filter

A damaged oil filter can cause oil to leak from the engine, leading to potential engine damage if not addressed promptly. The oil filter’s primary function is to remove contaminants from the oil as it circulates through the engine. Over time, the filter can become clogged, which can lead to increased pressure within the engine and cause the filter to fail. 

Failing Filler Cap

The oil filler cap is an essential component of the engine oil system. A failing or loose filler cap can cause oil to leak from the engine and onto the ground. If the cap is damaged, worn, or not tightened correctly, it can allow oil to escape and lead to a significant loss of oil over time. If you notice oil stains or puddles under your vehicle or have a sudden drop in oil level, the filler cap may be the culprit. Inspect the cap for any signs of wear or damage and replace it if necessary to prevent further oil loss.

Excess Engine Oil

Adding too much oil to the engine can also cause oil leaks. When there is too much oil in the engine, it can cause the oil to foam, which can lead to increased pressure and force oil out of the seals and gaskets. If you suspect that you have overfilled your engine with oil, it’s essential to drain the excess oil and refill it correctly to prevent further engine damage and oil leaks.
