I need an ///M doctor opinion
Hey people... so this morning I pulled into my job's parking lot doing about 20 mph its a long entrance.... when the left front tire touched the 15 degree incline I heard a snap! I could tell that some thing was not right but I parked and when to work. Then at 5:30 I started the car and to me it sounds louder and I could feel more vibration even at idle.
I drove home shifting at 3k hoping that it won't leave me half way home... but I made. I just took this pic and I would like to know what you think might be broken now. |

Krap! I phreaken knew it.... but I was hoping that it wasn't.
How many motor mounts do we have on the Z4ms? I see two so far. How difficult is it to replace them.... do you know? |

Thanks gents, I guess it was a prefect timing.... I just got my headers from Donovan yesterday, so I guess I'll be doing both jobs at once.
Any danger if I drive it gently the way it is? |

I wouldn't even attempt to drive it with a broken motor mount. It's most likely not the mount that's broken, but rather the bolts holding the engine to the mount are broken. I just proactively replaced mine with the motorsport bolts a few months ago, hoping to avoid issue like this.

Well, I just order a set of AKG motor mounts... I guess I'm going all out now.
I know this will make the car louder and the vibration will increase... but I'm not worry about that since I drive with my windows down 95% of time and my shifting problems will be gone. I'm also putting up my euro headers at the same time so the Z4M is going to sound and feel really nice once I'm done. http://www.akgmotorsport.com/catalog...Trans%20Mounts |

When your car is cold, stick your hand down into your engine bay and you can feel the actual bolts if you know where to look. |

Just so I'm clear, you need to order 4 of each of the screws and a washer for each, correct?

Correct 4 bolts for each mount.
I'd highly recommend looking into the NordLock washers (available thru places like McMaster Carr) BTW The passenger side mount is accessible only from underneath. However the drivers side mount can all be done from above, just need an assortment of ratchet extensions & swivel joints. |

I imagine that if the bolts have not snapped, then you can remove and replace one at a time without perhaps keeping a jack/block of wood under the oil pan?

Ah, another project!
Questions: 1. If using the Nordlocks, should loc-tite also be used? (seen both sides of this in posts, Nordlock website seems to say "no") 2. When using Motorsports bolts and Nordlocks it seems the torque spec. is 22Nm. What is the 59Nm +90 degree spec. I see mentioned. As always, thanks! |
