um it's possible it may not be fully game over yet for the engine... You can try putting some ATF and cranking it by hand.. hopefuly it will loosen it up (assuming there's no physical damage) |

I am curious as to how the engine seized? Was it a small leak at first and developed into a large one? Did you run it with little oil while on the highway to cause it to seize? Reason why I asked is my old X5 4.8i had a small leak for a week and all the sudden started leaking a massive amount while driving on the highway (you could see oil leaking when looking under the car). I was so fed up I just traded it in with the leak and accepted the small amount the dealer offered so I unfortunately do not have any answers as to what broke.

Shop was able to restart but it's running badly. Smoke test shows leakage in the right bank. I'm hoping it isn't a total engine write-off (truck is perfect otherwise), but bracing for the worst. |

That is how everything starts,for me too.Modern BMWs work at coolant temperatures up to 230F,and to keep the coolant from boiling the pressure is up to 20 lbs.There is no small leak in a system with a 20 lbs of pressure.Every small leak turns into disaster sooner than later.Once a leak starts,the system starts to loose pressure,causing the coolant to start boiling,which in turn raises the pressure even more,which in turn is pushing more coolant thru the small leak and so on.
My first '99 528i had a pinhole in the expansion tank and i was checking it every day and everything was under control until it was not anymore. |

No kidding,ehhh
But I am curious how a small oil leak turned into this huge leak without mechanical damage to the engine.Maybe there is a crankcase pressure related somehow. |

Gain just a wild ass guess, but it's on of those things that are part of the trademark like the kidney grill, the roundel, inability to design cup holders, thermostats, waterpumps, and so forth... |

You are right: I've replaced the gasket of the alternator bracket/oil filter bracket in all my BMWs for them the M44 in the first Z3 to all the M52s and M54s cars... In all of them was never catastrophic just an annoying seepage. Btw, I'm entirely unfamiliar with the V8, I just got interested since you hardly read of a BMW engine seizing... |
