“When I drive my car back to home, sudden noise from the front of the engine and found out the power steering pump and belts were off and sheared off some bolts around the holding. After the repair at the time on 5/1/2012, engine starts discovering oil leak around the front cylinder head housing. Keeping the oil level up to the require level for the past year. As of today 11/21/2013, I discovered the reason why the cylinder head housing is leaking oil is 2 sheared off bolts on top of the head housing. …”

“Head bolts to the engine are made of aluminum. These bolt the upper portion of the head gasket. This is a known problem. At least 1 aluminum cylinder head bolt is broken and there may be 3 more broken in my car. It is a known issue with this e61 touring vehicle. Bmw has designed an aluminum head bolt that is known to break at the tensions they specify in their manuals when they created the car. Currently, unless the broken bolt pieces are recovered the engine may have complete failure while driving and cause an accident. …”

“Bmw over-torqued the four cylinder head bolts on all n52 engines during manufacture, including my car. The bolt heads are popping off on all the cars, resulting in potential catastrophic engine damage at speed and minimally thousands of dollars in repair costs. The issue is a well known defect in how Bmw built these engines (affecting many, many 5 series cars) but is taking absolutely no responsibility for this. This is not a maintenance issue or anything owner-related -- it's purely a mistake by Bmw that they refuse to take responsibility for and to cover repair costs. …”
