No, not rings if it only does it at start-up & goes away while driving....that's oil leaking past the valve seal while the engine sits & burning off when you start the engine.
Is it just on start up? If so, could be something as simple as hardened or cracked valve stem seals.
Oil from the top seeps down the stem and into the cylinder while the car is parked, then burns off in a quick cloud when the car is started up. It's almost undetectable at other times.
Lucus oil treatment will help with this....not as good as repair but it will help. Other don't think it's tastes as good though...at least as not as good as chicken.
Get one of those valve spring compressors that just squeeses the spring and one of those adapters for an air chuck so you can pressurize the cylinders and keep the valve up in place while you take the keepers out and remove the spring and seal.

and, if you don't have air (or the adaptor), grab about 20 feet pf 1/4" rope, tie a knot in the bight end, roll the piston for the cylinder in question down, stuff the rope into the cylinder, then roll the piston up.
Hard.
That will hold the valves shut while you remove the keepers and springs for seal replacement......
Could this be the same problem I have with my MGB? Not at start-up, but just puffs some smoke once in awhile. Not on decelaration, just now and again when driving in traffic. Not at higher speeds.
