Installation Errors

Improper installation of car parts can lead to oil leaks. This includes over-tightening or unevenly tightening components like the oil pan or valve cover, incorrectly attached oil filters, faulty seals around the oil pump, or improperly fitted hose clamps on pipelines.

Physical Damage

Your vehicle's oil pans and gaskets are vulnerable to damage from road debris. Potholes, stone chips, and other hazards can puncture or tear these components, resulting in oil leaks.

Excessive Heat

Engines and oil have maximum operating temperatures, but when exposed to excessive heat, oil can thin out and seep through seals. High temperatures can also accelerate the aging process of gaskets, seals, and hoses.

Overfilling Engine Oil

Adding too much oil to your engine can cause an overflow, leading to leaks through valves and breather hoses.

Common Leak Locations
