Hi, use to have one 3-4 years ago, sold that one and now bought a 1992 black Ty. The Ty has some minor smoke when I get punch the gas. The smoke seems to be comming from the dash/steering column area. The smoke goes away after about ten minutes of driving. The guy told me (bought on ebay, shipped) it was the vavle stem seal. So, he did tell me. My question is, is this a major problem and if so, how much would it be to fix it. Overall the car runs good (13-15 psi of boost). Thanks, Steve
