When I start up my B18C, it sounds like a belt is slipping or like its sucking/blowing in air somehwere. There is kinda of a little squeak too. When its cold outside, it will do it for like 2-3 seconds then abrubtly stop. If it is warm outside it does it for like 1/2-1 second then stops. Its coming from the cam side of the motor and have listened to it, but I can find exactly where its coming from. Again, this only happens when I start it and never goes for longer than 3 seconds. Anyone have any ideas/suggestions on what to try/what it might be? I want to drive my car 3 gours north this weekend, but not if this is a larger problem than I am thinking it is. Thanks.
