Strange burning smell

[al & chris]

Got a strange burning smell seems to be coming from exhaust. I noticed it when opening a gate when engine was running. Will check oil level tommorow but think that will be ok, no lights on dash and does not normaly lose oil. Any ideas ? Its a 2.5 diesel and i dont use veg oil or anything although i did put some redex in a couple of weeks back.

No not for a long time. Sure its coming out of tail pipe. Engine not hot just normal temp .

Maybe some sheet plastic off the road wrapped round the exhaust...? Or prop shaft..?? I've seen the prop wrapping plastic on a lorry i was in on the M4 a few years back.. Had to cut it off back at the depot..!

Just checked oil thats ok. Nothing stuck to exhaust. Runs fine so maybee its just a smelly load of fuel.

Back brakes or handbrake binding?

Not brakes have checked them.

Here is a reply from Olebrock on another similar thread, I think it may have hit the nail on the head........

Hi, I have just logged-in and seen this. It has taken me several months to sort my 'burnt rubber smell' - I solved the problem. Dont laff but the cause (on mine) is due to the high heat from the middle box (the one after the cat) and spreads to the (2) rubber exhaust mounts giving the burnt rubber smell. By wrapping aluminium (kitchen) foil around the top metal bars which the rubber mounts onto has solved my problem. You need to wrap the ally tight around the metal bar so that it acts as a heat-sink. I have removed the rubber mounts expecting to find them burnt but they are still ok and I re-fitted and used the ally trick. Maybe silicone exhaust mounts would solve the problem but until the rubber ones need replacing I'll stick to them using the missus foil. Give it ago - remember the foil must stay tightly wrapped around all the time, if the smell comes back I bet you will find the ally has become loose.
