Hold on there guys....

Hang on a second everyone. Yes, these motors are known for needing valve stem seals; no doubt about that. However, Agron80 indicated BLACK smoke being emitted from the tailpipe, not the blue tinted smoke correlating with oil burning. Black smoke is indicative of an excessively rich fuel mixture. Perhaps there is a mixture problem with his car in addition to its needing stem seals.
