low oil pressure
rectently purchased a 1995 b740i for my daughter. within a few days she had her first problem. no oil pressure. none at all!!!
first thing the mechanic said was that the bolts holding the oil pump in place in this particular have a tendancy to back out, thus the oil pump loosens, and creates a LOW or NO oil pressure situation.
he pulled the pan on the bottom of the engine, and he was correct. however, in my case the bolt directly above the chain driven oil pump sprocket, had loosened so much that it dropped onto the chain as it turned the oil pump sprocket. the sprocket was bent and the chain broken, but otherwise no damage.
