If i ever take my runner up past about 3400 RPM's which is extremly rare it makes a funny smell


i sware it smells like oil but this thing doesnt burn a drop?

Nothing leaks on this thing and it doesnt consume any fluids..

what the heck is it?

 

may be the grease from your front drive shaft u joints is splattering all over the exhaust ?

 

Anything new installed?

 

hmm no new mods but my T-case was rebuilt all my axles have been recently greased and my ALL of my fluids flushed

 

nobody has any ideas?

bump

 

Maybe, at the higher RPM's, you're running richer and your O2 sensor is having to work a little harder and that's what you're smelling.

 

i dunno i probably could use a new O2 sensor mine is probably still orginal...and i DEFINTLY know i need a PCV valve

mine is 117,777 miles old

 

I'll second the "DEFINTLY" part on the O2 and PCV... Damn 89, you've got some serious mileage on those.

 

maybe check engine coolant? i know mine made nasty smells when i was at high rpm's, and i checked the engine coolant and was almost bone dry. i added more and now its fine.
