Blue-tinted smoke is an indicator of oil in the exhaust, could be piston ring blowby or valve guide blowby, a leak down test will help you determine what is going on.

Bad rings like to burn oil all the time, valve seals you manly see on start up and/or heavy acceleration. Your not going to get blue smoke from an intake gasket, and won't usually see that from a head gasket either
