Two problems related to engine oil leaking have been reported for the 2004 BMW 325. The most recently reported issues are listed below.
Vehicle leaks large amounts oil from valve gasket cover and oil filter housing compartment. I believe the engine block must have loose bolts which is causing the oil to leak and further cause a hazard in a possible engine fire due to this assembly of the engine. I am assuming BMW is well aware of this issue and believe a recall should be available.
The contact owns a 2004 BMW 325i. The contact stated that while driving approximately 30 mph, the engine stalled without prior warning. The engine restarted and the vehicle resumed; however within five miles the failure recurred. The vehicle failed to restart and was towed to an authorized dealer. The technician stated that the engine exhibited a crack. The vehicle may possibly be repaired for the defect. In 2007, the engine was leaking a significant amount of oil and an unknown repair was performed by the dealer. In addition, the air condition compressor was replaced by the dealer three times. The manufacturer was notified of the problem. The approximate failure mileage was 50,000.
