Oil Leak

Finding a dark puddle under your car is never fun. But oil leaks range from a $30 fix to a major job — let's figure out which one you're dealing with.

Oil leaks come from gaskets, seals, and fittings that deteriorate over time. The most common sources are the valve cover gasket (top of the engine — drips down the sides), the oil pan gasket (bottom of the engine — drips straight down), the oil drain plug (loose or stripped from oil changes), and the oil filter (improperly seated or old O-ring). Less common but more expensive are the front and rear main crankshaft seals, the timing cover gasket, and the oil cooler lines.

Florida's heat is hard on rubber gaskets and seals. High underhood temperatures accelerate the hardening and shrinking of rubber components, which is why oil leaks tend to develop faster in hot climates. To find the source, clean the area with degreaser, then run the engine and watch for fresh oil appearing. Sometimes UV dye is added to the oil and traced with a blacklight for hard-to-find leaks. The severity matters too — a slow seep that loses a quart over 3,000 miles is manageable, while a steady drip is urgent.
