Yeah it only happens when i coast along the road or going down a hill, then when i push for the gas to go back up the hill or more speed, that is when the blue smoke comes out.
But apart from that the car runs fine.
The way I interpret that is you only get the smoke when accelerating up a hill or alternatively when the motor is under load.....not when coasting along the road.
That's not how I interpreted it
"apart from that the car runs fine" suggests that it quite possibly is not worn rings a compression or leak down test may be able to tell you more...
The reason you get a puff of smoke when you accelerate (for those that don't know) is the engine is doing little work (not under load) so oil builds up in the cylinders and isn't being burnt off as soon as you hit the accelerator a whole heap of accumulated oil gets burn off and you get a puff of smoke.
But AFAIK worn rings aren't the only way for oil to get into the combustion chambers as suggested worn valve stem oil seals could be the culprut and as these will be cheaper and easier to check I would look here first. Doc suggested the the viton ones available from the austinamerica website (according to this site the original valve stems seals weren't all that reliable).
added to this the fact that otherwise there is not a problem power wise this sounds like the case that stem seals are to blame
Is it using excessive amounts of oil
How long was the hill you were coasting down if it was a long hill then the oil may have accumulated over a longer time and you might be worrying about a small more normal amount of oil getting into the cylinders.
If I am wrong with any of the above sorry and correct me but I would be hesitant at saying you need a rebuild.
