smoking exhaust

[mojobaby]

thanks everyone for being so patient! I think I might have made a breakthrough today!
Firstly I've sent some photos to show the pipes, and the plastic cyclone oil separator(thanks Angel).
Basically the pipe runs from the dipstick, through the plastic cone and to the carb.
On the way there, there is a pipe from the cone to the rocker cover breather pipe, also just before the carb a T-piece runs another pipe to the inlet manifold at the base of the carb.
Today I checked air pressure at the ends of all pipes. There was a lot of pressure from the breather pipe and this blows towards and into the plastic cyclone cone. The tube was also bunged up with old hard oil sludge.
That didn't make sense to me so I pulled off the pipe at the breather tube and went up killer hill and NO SMOKE! What do you think?
I'm so happy now! My car is called Genevieve by the way!

Thinking logically - Never a good thing to do

For the cyclone to work you need some pressure - the cyclone should separate the oil and all be fine - is the cyclone definitely clean inside and not blocked ? (Same with the drain pipe from it) ?

thanks Andrew, the only real pressure came from the rocker cover breather pipe that leads to the cyclone. That pipe, I discovered later, was blocked half way down. I haven't connected it again and tried it, I'm just so happy that the smoking exhaust has stopped. The cyclone itself is clean inside.
I've had the car since 2002 but really only driven it seriously since we moved here from South Africa 4 years ago. The cyclone system has always been there but only started playing up in Feb when we had that hectic cold weather.
It was so bad that the inside of my carb was coated with oil
