    Strange problem: oil leaking from air shutters

    Hello. Upon relighting my Anthes natural gas furnace, I noticed a gurgling sound followed by oil dripping from the air shutters! This furnace is located in my garage and has been turned off for the past 7 or 8 months, with the natural gas supply line closed. The oil is light, and straw colored. The furnace has a Honeywell gas valve with a 24V transformer. Is it possible that this oil is transformer coolant? If so, could it possibly be toxic? (the furnace is at least 20 years old). Thanks in advance for any help.

    What are you referring to as "air shutters"?

    Is this a ducted type of furnace or a unit heater that only heats the garage?

    Is it vented? How is it vented?, and ye shall find;..

    If I'm following your description, it sounds like its something in the supply line. Maybe water thats condensed in the line. The transformer used doesn't have oil in it. You might want to have a contractor or gas supplier take a look.
