Do you know exactly what cylinder is misfiring. From my experience white smoke coming out the tailpipe is a sign of oil burning most common cause is oil burning.valve stem seal most likely worn or cracked. Best to change all seals. Easier to do with heads off but then that means you will need a head gasket kit. However the valve stem seals can be replaced without removing the head just have to be careful and make sure the cylinder you're doing the valve change on is at TDC top dead center. What's the average compression reading on the cylinders what's your lowest compression on the cylinders.
