burning smell while engine running
 

im starting to smell a burning smell while i was let the car run in the driveway for a bit. could it be a belt or something?

94 es300 182,000 miles

Tapet cover gasket and/or rear crank shaft seal

if its the tapet cover then it shouldnt cost much to fix but if its the rear crank, then use thicker oil (cheaper way)

hope this helps and hope im right hehe

Did you have an oil change recently?

You have oil making contact with heat somewhere.
