Secondary Cause: Leaking Fuel Injectors or O-Rings Fuel injectors are precision units designed to deliver a fine mist of fuel into the combustion chamber, and they rely on specific seals to maintain this directionality. Over time, the O-ring seals at the top of the injector, where it meets the fuel rail, can dry out, crack, or simply wear out.

When these seals fail, high-pressure fuel can leak backward into the engine’s intake manifold or, in some severe cases, bypass the piston rings and drip directly into the oil pan.
