Burnt Rubber Smell

Bandit Runner

Senior Member
Lately I've been noticing a distinct burnt rubber smell after driving the 4Runner. I don't notice it inside the truck, but as soon as I park and get outside I can smell it. My son and wife have noticed it also.

Has anyone else ever had this happen? Any ideas on what it could be?

Thanks

Common: Belts slipping, dragging.
Less common: Hot tires from dragging brakes.
Also: Rubber part or hose has come in contact with hot exhaust somewhere.

Belt? Either loose or a failing bearing somewhere. Although I would think you would get a squeal.

I would also look for anything rubber near the exhaust, or the manifold. Maybe one of those rubber mounts for the exhaust broke and is dangling on the pipe somewhere.
 
Leaking valve cover gaskets like mentioned already. I had the same problem described.

Dripping oil onto the exhaust manifold = burning rubber smell.
 
Thanks for all the responses. You guys are awesome. Looks like I probably have the leaking valve cover gaskets.

Sounds like you may benefit from this video that [MENTION=102606]infamousRNR[/MENTION] and I made.

To those that do the valve cover gaskets, make sure you reseal the half moons in the back of the cylinder head with FIPG or RTV equivalent and replace the cam plugs as well. Also consider replacing the spark plug tube seals as well while the valve covers are off.
 
My valve covers have been leaking for many years now but recently it has gotten worse. It smells like "burnt rubber" and is most likely your issue.

Put me down for a valve cover gasket kit.
 
Chassis Grease

Another take: If you've recently greased your u-joints and driveline it could be excess grease getting onto the muffler and exhaust.
