3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I have recently bought an '01 330ci that has about 76,000 miles on it. The head gasket is blown and the mechanic that looked at it told me that the motor oil may be "burnt" so the entire motor needs to be replaced. Does that sound reasonable? The car actually appears to run okay except for the white smoke. (The guy only ran it for a few seconds. It started right up.) What are my options if the motor needs to be replaced? If not, what should replacing the head gasket cost me?
If the all almn. blocks get too hot they will warp and usually the threads for the head bolts get weak and you can not retorque a new head on it. I have seen this issue a few times at the last shop I worked at so the mechanic that told you it probably needs a new engine is right. I hope you got a good deal on the car because a 3.0L M54 is going to cost around $3500 for a used one. I think new ones sell for close to $8-$9K from the dealer.
