Smoke From Engine Bay
Happy New Year all! Been doing some reading and just wanted to get some second opinions.
Been running okay, but it started up and got some smoke from the engine bay and kind of a weird sound. Thankfully the smoke went away quickly and I think the sound got a little better but still seems to be there (can't think of a away to describe it, just not quite right). Still getting 25mpg on freeway, maybe not quite as peppy but it's hard to tell because of winter tires/excess stuff, a/c seems to blowing fine but not ice cold like it should be, in fact not even as cold as outside air temperature which is 40F here right now. Car isn't throwing any codes or anything, although haven't checked a/c unit codes yet.
After cracking hood I am leaning toward one or two ideas for the smoke:
1. I have a pretty constant light oil seepage because I've never done those gaskets, usually just get a slight film going down side of engine and I assume it kind fo burns off slowly somewhere. It asks for a quart or two of oil between changes. Maybe there was a little more seepage than normal and that caused the noticeable smoke?
2. Looking at the ac pulley, there is a fine black line of splattered oil or burnt rubber that is right in line with the pulley and sprayed all up the windshield fluid reservoir. Comes off on my finger so maybe oil but I don't know maybe rubber or something? Anyway the pulley looks like there might be the beginning of some rubber seals warping, or maybe it's always been like that I've never looked at it. But from other forum posts it sounds like maybe it is beginning to seize which maybe explains the a/c not blowing cold? So maybe that pulley needs to be replaced or the whole thing?
This sound familiar to anyone? Leaning to #2 since the #1 has been pretty unchanged for many years. If so is it safe to drive, worth fixing?
