idosubaru Posted January 4, 2006 Share Posted January 4, 2006 look at your axles, a broken CV boot will spray oil on the exhaust and it burns off and smells like burning something...oil you might say. pop the hood and look down where the axle (only shaft that goes from the tire to the transmission), there's a rubber boot on each end of the axle. inspect it to see if it's broken. note, the broken or cracked portion could be on the side you can't see by looking under the hood, inspect all the way around. usually it'll be obvious by grease spattering and coming out of it. it'll be wet. the grease gets on the exhaust and smokes off. this isn't a huge deal. $150-$200 to replace but it's not urgent...except the smell. you can wait a looooong time to replace axles. any oil spots on the driveway, in the garage. that would point to an oil leak. small leaks are not the end of the world, nice to know where they are coming from though. i would not suspect a rear seal leakage though unless someone had the motor out previously (unlikely with low mileage). do you know why it was salvaged? that might help to know.

1 Lucky Texan Posted January 4, 2006 Share Posted January 4, 2006 Is the A/C working? The defroster engages the a/c compressor - and the refrigerant system has oil in it - a sensitive nose might smell it if the coil has a leak. Though it wouldn't smell 'burnt'. If it smells 'sweet'/toasted marshmallows that would be coolant. Doesn't take but only a drop or 2 of grease or oil to make a big stink on the exhaust!

nipper Posted January 4, 2006 Share Posted January 4, 2006 Defroster bypasses the REC switch, so fresh air comes in, and you suck up any fumes from under the hood. You have a fluid leak of somekind dripping on the pipes. nippper Quote Link to comment Share on other sites More sharing options...
