I'm brand new to this forum and it seems great. I have a 2002 BMW 530i. A couple weeks ago white smoke came out of the tailpipe. I took it to a place and they said I had a blown head gasket and my temperature gage broke and that's why it didn't say it overheated but no smoke came out from under the hood. I took it to another place for a second opinion and he replaced the following: Upper Radiator Hose because he said there was a leak in the plastic, and the Intake manifold gasket. He said he found a vaccuum leak. the intake manifold was leaking and a breather hose for the crank case. He replaced the boot and the intake gasket. He also said the temperature gage wasn't broken. All this cost me 674.64. When I was driving it home there was still white smoke coming out. I let it sit in my driveway for hours then started it up and white smoke again. I drove for a couple minutes, stopped, waited, then started again and no white smoke. I'm very frustrated because I don't know what's wrong with it and I'm dreading getting up in the morning and starting it to white smoke! I don't know much about cars so please help me with suggestions. Thanks!
