What bolt? I originally was trying to get just the snout off the blower without taking it off the intake because I didn't buy a replacement gasket until I realized that I couldn't clear the alternator (accesorry) bracket. I guess the M90 has a different setup which allows you to do it unless I missed something which I would be very interested in learning. Either way, I pulled the blower off today and changed the coupler, now I HAVE to get those gaskets/o-rings.
Was probably a good thing that I did it that way too, the blower gasket was HAMMERED from 131,000 miles and part of it had actually sucked in somehow (the part of the gasket that is on the farmost passenger side) and broken. Hadn't ever been off since it was built.
