My 914 daily driver has been having a bad smoking problem lately, it started out just smoking at idle after coming off of the freeway, and I would see a small amount of smoke while shifting between first and second gear. Though today while I was on the freeway in 5th gear doing probably 60mph, there was a steady stream of smoke coming out of the tail pipe. My car has a 2.oL engine with duel Dellarto carburetors, it runs very rich with a bad exhaust smell, but it has since I bought it a couple years ago. Last week I changed the oil, I was using a 10-30 valvoline, but I switched to a 20-50 brad penn oil. I haven’t done much to the engine in the time I have had the car other than change the oil and adjust the valves. Oh, the smoke is a mostly white grey color, so my question is, is this an obvious problem of warn rings that would warrant a rebuild? Or is there other solutions to try, (there is no reduction in power that I have noticed)
Any and all advice would be greatly appreciated; it has gotten to the point that it is unpleasant to drive the car.

When was the last time you did compression testing?

Adjust your valves, warm the engine, pull the spark plugs, open the throttle, have a helper crank while you measure compression with a tester from FLAPS.

Probably the rich tune has led to early ring wear due to the fuel washing oil off the rings. This is causing oil to burn up, which causes lots of smoke.
