I’m not knowledgeable in cars, but the other day my alternator went out in my 2010 Touring. First the “check battery system” light came on, then a few moments later every single light started flashing. Apparently the “valve cover gasket" was leaking into the alternator and killed it. That's according to the mechanic. So I have a new alternator, and he told me I'd be ok driving it a couple weeks (which I'm uneasy about) before I have to get the gasket replaced. My question is what is an average cost for the parts and labor for this kind of job? I think I have been getting ripped off by him, so I'd like to know going in what I'm looking at cost wise. I don't think I'll drive much until I can get it fixed because it makes me very nervous. Any help would be appreciated. thanks!
