Like I said this time it had been sitting, but it does smoke some even when it doesn't sit, but always goes away...is this just a symptom of an old vehicle...oil level is fine, maybe some lucas would help?

Smoke on start up that goes away can have several causes that I know of. One it could be actually steam from moisture in the the engine and exhaust system.
It could be oil that has seeped around the vavle stems and leaked in to the combustion chambers. Normally it is a blue puff at start up only.
Or it could be oil bypassing the rings that have lost some of their ability to seal untill you get some heat in the engine. Do you have to add oil often? Do you have to add coolant often? What color is the smoke? Does it do it when it is warm outside?
