I just wanted to ask a question about my dads 2004 525i. There was no damage or accident to the car but yesterday, a white smoke came out of the exhaust pipe upon ignition. I have researched it and apparently the 5 series has a problem with broken head gaskets. Currently, there is no warranty on the car and he has given it to his friend's repair shop. He has updated us that the engine of the car seems to have a problem and it is expected that the whole engine has to be taken out for inspection. What seems to be the problem in the car? Is there a possibility of replacing the whole engine? It is expected to cost quiet a bit.

P.S. Currently my dad is using my 328i and I am carless!!

idk about the gaskets but white smoke from the exhaust can also be caused by either by not having enough fuel or Catalyst converter being dead.

White smoke can and usually DOES come from coolant burn off in the oil due to a leaking or blown head gasket, cracked head etc. Hopefully he didnt crack the head or the blocks cuz that means $$$$ for a new motor. At that point your dad should just throw an M5 motor in there.
