BMW Oil Leaks
Oil leaks are one of the most common and frustrating issues faced by BMW owners. Whether you’re driving a 328i with the N20 engine or a 535i with the N55, chances are you’ve encountered a small oil spot in the driveway—or worse, a burning smell from under the hood. At Torrance Motors, we specialize in diagnosing and repairing BMW oil leaks quickly and cleanly.
Common Oil Leak Sources in BMW Engines
BMW engines are known for performance and precision, but some components are prone to wear and leakage over time. The most common culprits include:
- Valve Cover Gasket: A notorious leak point on the N52, N55, and B58 engines. Often causes burning oil smell and oil in spark plug wells.
- Oil Filter Housing Gasket (OFHG): Fails on most engines around 60k–90k miles. Can leak onto the serpentine belt, leading to serious damage.
- Oil Pan Gasket: Leaks from here are messy and can coat the undercarriage in oil. Requires engine support or subframe drop to repair.
- Turbo Oil Lines: On turbocharged engines like the N54 and N20, return lines can leak over time.
We’ve seen it all—and we know how to fix it right the first time.
Symptoms of a BMW Oil Leak:
- Visible oil on the ground under the car
- Burning oil smell when engine is hot
- Smoke from engine bay or exhaust
- Low oil warning light
- Oil buildup on engine components
Ignoring oil leaks can result in serious engine damage or even a fire hazard. That’s why our BMW-certified technicians inspect each leak carefully and explain exactly what’s causing the problem.
