BMW cars are built for precision, performance, and an unmatched driving experience. But even the most refined machines need regular care to keep running smoothly. One of the most frequent issues BMW owners face is oil leakage — a small problem that can turn into a major headache if ignored.
Understanding why oil leaks happen can help prevent serious engine damage and save you from expensive repairs later.
At XL Car Care, a trusted BMW Service Center in Delhi NCR, we’ve handled countless oil leak cases for BMWs and other premium vehicles like Jaguar and Land Rover.
experienced technicians know exactly what to look for and how to fix it the right way. Let’s take a closer look at what typically causes oil leaks in BMW engines.
Worn Valve Cover Gasket
The valve cover gasket seals the top of your engine and keeps oil from escaping. Over time, constant heat exposure causes the gasket to harden and crack, leading to leaks. If you’ve noticed oil around the valve cover or a burning smell when the engine is hot, this is usually the culprit.
Replacing the valve cover gasket at a professional BMW Service Center in Delhi NCR ensures it’s installed correctly and that any related issues, like clogged PCV systems or warped covers, are fixed at the same time.
Damaged Oil Filter Housing Gasket
Another common source of oil leaks is the oil filter housing gasket — the part that connects the oil filter to the engine block. When this gasket wears out, oil can start seeping out slowly.
At XL Car Care, we often see cars that were serviced elsewhere using low-quality parts or improper fitting techniques, which can make the problem worse. That’s why it’s important to visit an experienced Jaguar Service Center in Delhi or Land Rover Car Repair and Service Center in Delhi NCR like ours, where only genuine components and precision tools are used.
Faulty Oil Pan Gasket
The oil pan gasket sits at the bottom of your engine and seals the oil pan to prevent leaks. When it gets damaged, you might notice oil spots under your parked car.
Replacing this gasket isn’t as simple as it looks. BMW engines are complex, and the process often requires removing suspension parts or underbody panels. At XL Car Care, our certified technicians follow BMW’s service procedures to make sure the repair is done properly — no shortcuts, no loose ends.
Cracked or Worn-Out Engine Seals
Over time, engine seals such as the crankshaft or camshaft seals can deteriorate. These seals are under constant pressure and temperature changes, which can eventually cause them to fail and leak oil.
Our advanced diagnostic systems help pinpoint even the tiniest leaks, so they can be fixed before they turn into something serious. Along with BMW, we offer the same expertise for Jaguar Repair and Land Rover Car Repair and Service Center in Delhi NCR, ensuring every luxury car receives precise and reliable service.
PCV System Malfunction
The Positive Crankcase Ventilation (PCV) system helps control pressure inside the engine. When it malfunctions, excessive pressure builds up, forcing oil out through seals and gaskets. This is especially common in turbocharged BMW engines.
At XL Car Care, our team checks the PCV system during every BMW Service appointment. If a valve or hose is blocked or damaged, we replace it right away to prevent future leaks and performance issues.
Overfilled or Improper Oil Change
Oil leaks aren’t always due to a bad gasket or seal — sometimes they happen because of incorrect oil changes. Using the wrong oil grade or overfilling can increase internal pressure, pushing oil out of weak spots. Even a simple mistake like reusing an old drain plug washer can lead to slow leaks over time.
That’s why our technicians at XL Car Care handle oil changes with utmost care, following manufacturer guidelines for oil type, level, and torque specifications. You get peace of mind knowing your BMW’s engine is serviced exactly as it should be.
