Normal? Maybe....all mine do it! You are probably running rich or maybe a
little valve guide wear that is letting a little oil creep into the engine when
its sitting.
Get someone to follow you, warm up the car, find a steep hill. Then while
decending the hill let up of the gas....if the observer observes a puff of
smoke
when you do that, its an indication of worn valve guides. Most likely tho,
your SU Carbs need to leaned a wee bit.
