Leaks

As cars get older and driven, heat cycles and use can lead to rubber gaskets inside your engine to become tired and break down allowing vital fluids to leak out of your car which can lead to major mechanical failures. Engine Oil, Power Steering, Coolant, Transmisison fluid etc.

Oil Filter Housing

One of the very common oil leaks in most BMW models is around the Oil Filter Housing. This housing is metal or plastic and is bolted directly to the engine block. This housing not only has all of the engine oil going through it but also shares coolant passages as well. Over time with all of the heating and cooling that housing sees, it weakens the one rubber gasket they have separating everything. Once this gasket lets go you run the possibility of leaking both oil and coolant but also could have them mix internally which is detrimental to the health of your engine.

Improper service of the Oil Filter Housing leaks can lead to other issues like serpentine belt failure which can leave you stranded. Serpentine belt is used to connect devices like the alternator and power steering pump to the engine. In some cases the waterpump is powered from the serpentine belt which can lead to engine overheating if failed.

Valve Cover Seals

Valve covers are prone to the same issues. Valve covers are responsible for keeping your vital internal engine components safe away from the environment as well as maintaining a sealed area for oil to be sprayed around the engine. Failure on the valve covers can be very dangerous. Leaking oil can travel down the side of the engine and in some cases end up on the exhaust. The beginning part of your exhaust on any car is where there is the most heat. This heat can bring the oil to its flash point and start a fire that can be very hard to control.

Oil Pan Gasket

The oil pan is where the majority of engine oil sits in a car at any given time. The oil pan is also the location of vital engine components such as the oil pump itself as well as your crankshaft and rod bearings. Leaks around the oil pan can lead to quick engine oil loss and damage to those components which can be a costly job.

Turbo Line Seals

Almost every turbo out there is designed with high heat and lubrication in mind to keep it spinning at its highest potential. There are lines that come from your engines oil supply and send it through the turbos to cool and lubricate the metals inside. This oil is only held inside by small o-ring gaskets and one small mental crush gasket that over time can leak and cause oil starvation to your turbos eventually causing them to fail or even start leaking oil inside of the engine causing smoke and burning oil smells.

Transmssion seals

Almost every automatic transmission has an external oil cooler attached to it. These coolers are connected to the engine coolant system to assist in heat transfer away from the transmission. Leaks in these lines can lead to low fluid levels and even damage to the vital gears and clutches. Manual cars suffer from leaks too. Output shaft seals, shifter seals, pan gaskets, fill and drain plugs can also leak fluid.

Front Or Rear Crankshaft Seals

Engines like the N54 and N55 are unfortunately susceptible to serpentine belt failure due to other oil leaks. Those leaks break down the rubber and in some cases can send the belt up behind the crank shaft pulley, pushing that belt into the engine oil pan. This belt material in the pan can lead to clogging up the oil pick up starving the engine of oil and causing damage. Rear main seals are also exposed to intense heat and rotation and cause oil to leak out behind the transmission.
