I have a 65 Corsa with a rebuilt Engine and heater system. (Fan Motor, Heater Tubes etc.) I get a gas smell when the engine comes up on boost or under load, like going up a hill. What can I do to get rid of the smells ? Rick Sanford Werres Corporation 800-638-6563x236 office 301-748-4441 cell rsanford at werres.com www.werres.com
