because there is no air conditioning topic, i figure i'd throw this up here...
ever since i've owned this boat (aug of 2004), i've noticed a fueley, oiley smell in the salon, ONLY when i put on the salon air conditioner after a run. a little background...
the boat has two a/c units - a new 7000 btu unit under the forward berth that does the forward stateroom and the head. the second is in the salon, under the port side dinette - it's a 16000 btu unit (original) that services the salon and the second stateroom (which is a mid-cabin room beneath the raised dinette in the salon). this is the unit that produces the "smell." it is ONLY after the boat has been run - ie: when we come down for the weekend, open the boat up and turn the a/c on, it has no smell. the a/c unit is on the port side, forward of and bulkheaded off from the engine room and the ducts don't traverse the engine room at all, although the one that goes to the mid-cabin probably runs beneath the port side gunnel, which could be contiguous with the engine room (?). but there is no smell in the second statroom - only the salon. also, after a run, if i do NOT put the a/c on, there is no smell.
the smell is hard to describe - it isnt gasoline, it isnt dripped oil on a hot manifold, yet it's some weird combination of both. it isnt particularly strong, but it is noticeable. does that make sense to anyone????:huh:
there are no fuel leaks or porous fuel lines - i have scoured the pathway of gasoline from tank to filters to carb and nothing has turned up - keep in mind this is a 3 year ongoing thing and in that three years, being a DIYer, i have spent an awful lot of time in that bilge and engine room. there is never any fuel smell in the engine room. i do have a slight oil drip that i just noticed, probably from the left valve cover gasket on the stbd engine that needs tightening, but it is easily absorbed by a bilge absorbant thingy that i keep in place. this amounted to about 1/2 quart from last october's oil change to this october's.
any ideas???:smt017
