I'm looking at a 2000 540i 6spd and the owner describes it as having a couple problems that I'm wondering if they are known as common issues and what it would take to get them fixed.
In addition to the water pump squeaking, he says oil is leaking into the engine so after the car is turned off and sits for a bit it makes smoke upon startup. He said it doesn't smoke after it has been running for a little bit.
Not sure if the two issues are related or not. Is the water pump built in to the block and a PIA to replace? Any idea what could have failed to let oil leak into the engine when off?
