ashbuster Posted October 5, 2012 Share Posted October 5, 2012 (edited) hey guys lately ive had a burning rubber smell coming into the car and its mainly when high revs or flooring it everytime ive looked around the car but i cant find the problem. its not the tyres i know for sure. last things done to the car before this started happening was the exhaust was pulled up high and cable tied up higher so the carbon diffuser can be fitted, this diffuser is touching the exhaust (whats it smell like when hot?) also the crank pulley was changed and the idiot hit my aircon rad when he was doing it. its really annoying i cant seem to find the smell because it completely goes when im pulled over. could it possibly be my auxbelt slipping? and how would i know for sure, ive tried smelling all over the engine bay and cant smell anything forgot to mention, no warning lights show up and it doesnt overheat, coolant isnt going down and oil level is fine in the box and engine.

skippyboyo1 Posted October 5, 2012 Share Posted October 5, 2012 I'm struggling to understand what u mean.... Have you cable tied your exhaust up and left it like that? If So you need to get to a custom exhaust company and have it altered properly. Your exhaust should not be touching your diffuser as you Will melt it Quote Link to comment Share on other sites More sharing options...
Noz Posted October 5, 2012 Share Posted October 5, 2012 cable tied exhaust... smell or no smell you want to get that sorted dude Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 5, 2012 Author Share Posted October 5, 2012 dont worry about the cable ties, its only on the bracket parts to hold it up a little, i still have the rubbers on as normal, 1 cable tie around the bracket to hold it up a little simple.. i was told in another thread it wouldnt melt it???

skippyboyo1 Posted October 5, 2012 Share Posted October 5, 2012 If its touching the diffused it 100% will, carbon will burn Quote Link to comment Share on other sites More sharing options...
Kaan W Posted October 5, 2012 Share Posted October 5, 2012 Carbon burns? Yes at some degree of heat carbon will burn but not from the silly tempereture a back box reaches. If your back box was glowing red then yeah lol. Besides my difuser was touching the whole underneith of my back box and never had problem. I would put my guess on the aux belt slipping mate.

thomo8568 Posted October 5, 2012 Share Posted October 5, 2012 Have you got an auto? I was getting a strong smell in my car when my tps was playing up. Was more of a clutch smell tho. And only there when giving it some beans. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 5, 2012 Author Share Posted October 5, 2012 (edited) yeah mate its auto, clutch smells simular to brakes i would imagine, and this is different, more of a rubbery smell and the aux belt im using is one i was linked to by nic in another thread. the vents on my bonnet are right above it allowing it to get wet which im guessing doesnt help i smell it and cant smell the burning smell, wouldnt the smell still linger from the belt? just wanted to add i dont think it would be the backbox on the diffuser because i dont think i wouldnt be smelling that inside the car at 60mph would i? right at the rear, plus the smell is just like rubber / like tyres car still pulls and drives as it should Edited October 5, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 6, 2012 Share Posted October 6, 2012 Is the crank damper goosed again? Was it a new one or a used one? Tipex test it. O2 sensor lead draped on downpipe? Sadly only a small percentage here will be able to advise, as N/A owners will not have smelt burning rubber enough to meaningfully comment.....

ashbuster Posted October 6, 2012 Author Share Posted October 6, 2012 (edited) checked the lead and its fine, clueless on this one unless its what i thought and its the auxbelt slipping but how would i know for sure? without revving the shit out of it with the bonnet open, im in an area where they will all moan and complain lol i now live in farmland this is the belt i ordered http://www.ebay.co.uk/itm/350587553982?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 brand new i checked the routing and its fine Edited October 6, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...

Carbon 100% Burnes as stated. The diffusers are made part fibre glass so Burnes, I say this as I've had one burn. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 6, 2012 Author Share Posted October 6, 2012 (edited) today i lifted the bonnet and revved all the way to redline slowly and even tried quickly and all sorts and no burning smell at all. had the old people come out looking getting ready to complain but they dont know me so they didnt lol. even tho im nice to old people anyway im baffled even if carbon does burn i couldnt see it smelling like rubber ??? ive sanded this stuff with a air d.a and it didnt smell at all like rubber, the resin doesnt smell anything like it, Edited October 6, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 7, 2012 Author Share Posted October 7, 2012 would it make a difference that the car was revved in park rather than being driven under load to see if the belt was slipping? Quote Link to comment Share on other sites More sharing options...

ashbuster Posted October 7, 2012 Author Share Posted October 7, 2012 didnt think so , any ideas what to check next mate im running out of ideas Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 7, 2012 Share Posted October 7, 2012 Not something daft like overly wide tyres rubbing on the arch, inside or out, or on top if it's crazy low? Not sure if you are saying it's happening only when driving, or if it's reproducible when the car is stationary. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 7, 2012 Author Share Posted October 7, 2012 (edited) its baffled me lol, yeah mate my tryes are fine and not rubbing anywhere there is plenty of room and yes mate only when going along, cant seem to get it to do it while stationary. ill remove the diffuser tomorrow and try again but i really cant see it being the diffuser because it cant smell like rubber surely but atleast it will rule that out too i should have some spare time tomorrow to go over it properly Edited October 7, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted October 7, 2012 Share Posted October 7, 2012 Unless the back of the car is virtually on fire you won't smell an exhaust touching a faux carbon diffuser inside the car when on the move. I would look for the source in front of the heater intake at the base of the windscreen. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted October 7, 2012 Author Share Posted October 7, 2012 thanks chris ill post back tomorrow hopefully i find it the car had new antifreeze in but my aircon rad is damaged but that shouldnt give off a rubbery smell should it.
