Common problems with BMW 545i engine- 

1)BMW 545i engine Valve stem seal  

The work of the steam seal is to prevent oil present in the cylinder head to dip into the combustion chamber and also control the intake of lubrication in the exhaust valve. Also, the seals are made up of very poor quality material which degrades and brittles over time. So the steam valves of the 545i engine can develop some cracks and also allow some oil to pass through the combustion chamber. Also, there are 32stem valve seals in the 545i engine that may create a possibility of having one gasket faulty. So you need to be very careful regarding your gaskets to prevent any type of engine failure.    

2)BMW 545i engine Alternator Gasket/Bracket oil leak 

There is also a problem with the gasket oil leak like there is a common problem with the Valve stem seal. The oil leak is because of the design of the BMW 545i and has a cheap quality gasket that also degrades over the passage of time. Also as time passes the engine heat makes the gasket brittle and develops some cracks causing the oil leak. To predict a gasket oil leak you can observe the engine for any oil leak.
