So just replaced the 2 coolant pipes under the intake manifold and car is running fine but there is a burning toxic oil smell that I cannot place.



  • I ONLY smell it inside the car when car is in idle, not when it is moving
  • Smell is not coming from the vent, outside whether it is air/recirculating inside air, as I am smelling the vent air from the AC and it smells clean
  • It doesnt matter if I have the windows up or down, the smell comes into the car in idle
  • Smell starts pretty much within minutes of driving
  • Car temp is good this while time, coolant is good
  • Its been about 2 weeks not so I am thinking it cant be some spilled oil that is burning off, it should have all burned off already then
  • No visible smoke anywhere




So I am just confused as to how the smell is coming into my car, and obviously where it is coming from and the cause.
