70SportSedan Nov 5th, 04, 8:58 PM Hi, today I got my 307/350 1970 Malibu (recently bought) on the street; everything was going fine, except for the fact that I could smell burning rubber every time I floored the accelerator pedal. What's wrong? The worst thing for me at this time would be a transmission issue... Thanks in advance Claudio onick Nov 5th, 04, 10:41 PM if it only happens under hard acceleration, i would suspect transmission. Hopefully you are not burning anything electrical. Start by checking under the hood for anything that might be touching your exhaust manifold or headers. Tom's 68 Nov 6th, 04, 6:21 AM take a look under the car at the exhaust system make sure there are no exhaust hangers that have some of the rubber touching the pipe how new is the exhaust system? 70SportSedan Nov 6th, 04, 11:48 AM Onick: It does happen only under hard acceleration. Time for a tranny rebuild? Never drove an automatic before (they aren't common over here), so I couldn't tell how good or bad the transmission is. By the way, there is no smell under the hood. Tom: I'm afraid the exhaust system is the original, with some repairs. I got the muffler fixed just today, it had a big hole! Thanks for your replies Claudio onick Nov 6th, 04, 1:37 PM i'll send this post to the tranny section, see if those guys know the sypmtoms. http://www.chevelles.com/forum/ultimatebb.php/topic/28/6282.html Tom's 68 Nov 6th, 04, 5:07 PM did you notice that smell before you changed the muffler? Wally Nov 6th, 04, 7:04 PM Maybe the back tires are spinning smile.gif smile.gif smile.gif Tom's 68 Nov 6th, 04, 8:45 PM yeah love that smell 70SportSedan Nov 7th, 04, 9:09 AM Originally posted by Tom's 68 conv: did you notice that smell before you changed the muffler? Yes, before and after Originally posted by Wally: Maybe the back tires are spinning smile.gif smile.gif smile.gif I'd be very happy graemlins/hurray.gif Thanks Claudio Tom's 68 Nov 7th, 04, 4:00 PM how about loose belts? Olle Nov 12th, 04, 12:42 PM Originally posted by Wally: Maybe the back tires are spinning smile.gif smile.gif smile.gif :D LOL! That was my first thought too. Have you checked your engine/transmission mounts? Is there anything that can move, rub or touch hot parts when the engine moves under acceleration? Rick Bandy Nov 14th, 04, 10:58 AM I've been having the same problem.....let me know what you figure out! :rolleyes: http://www.chevelles.com/showroom/RickBandy/lightthetires.jpg 67Chevelleguy Nov 15th, 04, 2:58 PM Maybe the back tires are spinning yeah, that is a very common problem in Chevys, especially Chevelles. tongue.gif :D smile.gif ACLineman Nov 15th, 04, 5:14 PM My first thought was belts too. Higher RPM + Loose or worn belts = burning rubber smell, and not always squealing either. How did you suspect transmission with burning rubber smell???? 70SportSedan Nov 18th, 04, 4:51 PM Changed and tightened belts, no more smell!! I did suspect transmission because of my ignorance graemlins/sad.gif smile.gif Thanks to everyone! ACLineman Nov 18th, 04, 7:23 PM graemlins/beers.gif By the way, how is the sportfishing down in Chile? 70SportSedan Nov 20th, 04, 3:52 PM I'm not a sportfishing fan, but I would recomend my country for that purpose. South of Chile is plenty of fishing lodges, being november-december (trout) and march-april (salmon) the best time for fishing (I've heard). Fishermen from USA are abundant also... smile.gif chevelle_ss_396 Dec 10th, 04, 2:59 PM CLUTCH. I bet your clutch is bad. I've had that problem with both of my Saturns ... Good Luck ACLineman Dec 10th, 04, 10:57 PM Originally posted by 70SportSedan: Changed and tightened belts, no more smell!!
