if your tailpipe is pouring smoke then you have internal engine problems and need to take it to a mechanic or you need to change your oil

Why is oil leaking out of spark plug in your 1975 Chevy 350?
It's not. You need to replace valve cover gasket on that side. Now if your engine is smoking out of the exhaust and running real rough then you may have piston problems on that cylinder causing oil to come out of the spark plug hole. Rebuild time.
