I'm getting this burning smell off my engine after I've been out for about 20 minutes. There's no overheating. I checked the coolant. Checked to make sure the fan is rotating, and the belts are all ok.

What do y'all figure it might be?

Well, I'm filthy and spent some time practically in the engine compartment and I still can't find anything. No loose hoses or wires, everything seems to be in place. Dang it.

Are you leaking any oil or other fluids that could burn off against the block?

The valve cover (? top of the engine where you pour the oil in) has oil on it but I can't see how the oil was leaking up...

I was on some sorta steep grades monday but I don't think that would cause any issues.

IMHO

A common source of burinng is when road debris (like plastic bags) are swept up under the car and contact the catalytic converter. The cat is very hot (~900 degrees internally). Get under the car and look at your exhaust -- with it not running, unless you're crazy like me, and look for items stuck to the cat or on any other part that gets hot.

If the car is running and you can't see the source of the smoke looking in the engine compartment make sure you're not leaking oil. Look for changes in the amount of oil under the car when parked in a clean spot. A common problem is that oil or grease gets on a rotating part and is slung around -- contacting a hot exhaust part. That will cook off making smoke. if someone just changed the oil, they may have spilled some causing this.

Check you wheels. Make sure you're not leaking brake fluid (which should be announced beforehand by poorer braking action) -- or that there is no fluid visible near your rotor or brake calipers.

Look more carefully for wires or hoses that may be loose.

CAREFULLY observe your drive belt. Look for evidence of glazing or wear. Check to make sure the tension is right. Important: RUN THE ENGINE and make sure the belt and all of the pulleys that it contacts are is turining. You could have a frozen alternator pulley and your belt could be just rubbing away at it (instead of turning it). That could make smoke.

Hope this helps.

No oil leaking, it's brand new, so there's no spots under him. I checked to make sure everything was turning like it should, but I'll crawl back under it to make sure there's nothing stuck somewhere, though I can't see that I would miss it, I get distracted under there. No smoke, just the smell and it's really starting to irritate me.

But thanks guys, I'm rolling through the suggestions. :D

Mine always smells like that after I service the driveshaft. A little grease bcomes out the seals and blows onto the muffler-> the burning smell. Good luck.

Are you serious?? I thought that's what that big black thing was for. Tubey thingamajiggers in each sneaker and then the wirey thingamabobs go where the laces are. Drys them real nice. You only have to drive a few hundred miles before they're done.... :p wiseacre.

My first thought is - you better get a man over there to take a look at it. :flipoff:

Second thought - I don't have a clue. :confused:

Third thought - Go buy a Honda. ---->:flipoff: <---- :D
