Valve job? Cheapest way?

1991 Buick Spirit smokes early for five minutes in morning, from exhaust. Tried every carburator and gas cleanative fluid. Mechanic says Valve job'.


Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
