I just bought a 94 730i, UK specs. There appears to be an oil leak. Whenever I turn the car off, it leaks a saucer-sized amount of oil and then stops, and it doesn't leak while I'm driving.
I've heard this might be a head gasket and am gonna get it checked out soon, but can anyone fill me in on what else it may be? Ive heard it might be a loose bolt or something, I just want to make sure I know what's what before heading into the mechanic's. Basically looking not to get screwed on this.
