black94ls400

I am getting a strange smell when I put on the heat on, this odor is like smoke coming out of the exhaust Co2, and there is a hummy noise coming from the back on the passenger side when I stop for a light and also noise from the front of the driver side. Any help is welcome blackls400 1994

I got a ls 400 94 with 122k miles, after check it up at the dealer, they found taht I need mounts for the engine and tranny, rear knucles. Parts alone at the dealer would cost close to $1000.00. Now, the car did not come with a cd changer, only am/fm/tape, is it possible to place another lex radio with the changer, would there be any complications. Do any of you know where I could find these parts at a much cheaper price. By the way I smell gas I put the heat on, any fix on that matter thanks, black94ls400 Brooklyn
