Oil Smell through HVAC - Advice/Thoughts Please
Posted by: 1083HP (97314) on 2017-05-15 16:44:19	Share \| Report

Hi All,

Have an oil smell (suppose you could call it burning oil smell) coming through the HVAC when it is set to regular vent (fan only). If I turn on the A/C or press the recirculate button (with or without AC on), there is no smell.

Thoughts ? Don't have an oil leak (atleast no dripping on the driveway) and it doesn't seem to be burning oil. Anyone experienced this before ? Thoughts on what it could be ? Surely it is some sort of oil leak or oil burning situation - just wondering where/how it is entering the HVAC system and why it's gone when AC or recirculate is engaged.

Thanks for any feedback/prior experiences!

  - If it is a valve cover gasket, there's good reason why you might not be seeing in the driveway. - SteveAR 2017-05-15 17:31:52 (181 views)
