welcome, its good to have you on board!
note that the more info you include in a post, the better we are able to help you diagnose/correct a problem
at first thought it sounds like your valve stem seals.
if you want to do further testing before tearing it apart, it would be wise to do compresion tests dry and then wet (with oil). if the wet test gives higher readings, you're leaking around the rings. a small difference is normal, but a large difference means rings are worn out.
depending on your engine's age/history, its likely that both may be getting worn out

Color of smoke?
Blue = Oil (most liking from valve stems, but can be rings as well)
Black = Running too rich
White = Water/Coolant leak (possible head crack or leaking gasket)
Or, white is also just the normal exhaust color when cold and it's warming up the condensation collected in the exhaust pipes. You usually only worry about white smoke if it's heavy and won't go away.
Definitely need more info.

8) you it smokes when it is parked, does that mean when you go out to start up for the first time after it sits a while? if this is the case then it is likely condensation in the system that is burning off, or you may have a cracked exhaust valve seat.
or when you shut off after running for a while? if this is the case you may have something leaking on the exhaust.
or does it smoke after you have run it a while down the road, then you pull into a parking lot and let it idle for a minute before you shut it off? this might be due to a rich mixture.
as cobrasix pointed out though the color of the smoke would also be helpful.
maybe the car is in such a good mood it is having a cigarette :rolflmao: :rolflmao: :rolflmao:

Old thread revival... I figure it's better to keep info consolidated rather than start a new thread.
My 65 Falcon 200 runs like a champ but lets out a puff of oil smoke after it's warmed up and idles for a couple minutes. If I stop at a long traffic light it'll do it. The hotter the engine and the longer it idles, the bigger the puff of smoke. No (visible) smoke while driving down the road or idling but it does smell like an old tired engine.
I'm pretty sure my engine is just tired and needs to be gone through, but maybe the "six" gurus know something I don't. I was thinking about throwing some valve stem seals at it but I wonder if it's even worth it.
What do you guys think?
Thanks in advance.

If the engine is in good condition otherwise I would say it is worth it you can replace valve seals them with head still on the engine. Cost for parts would be low and only special tool needed is a small valve spring puller. Pull the valve cover and look to see if the valve seals have cracked or deteriorated.
Fist look at the plugs, for any kind of oil, either burnt or not. that will tell you which cyl to look at the most when you go through seals.
valve stem seals are really easy compared to some other things, if you do one (exhaust) then do the other (intake) for that cyl, it minimizes the likliness to know it's the rings if that cyl is smoking or not.

Thanks for the responses, fellas. I pulled valve cover off and the valve seals were virtually non existent. I'd say the most complete seal was only 25% there. There were remnants scattered throughout the head.
I put a new set of seals on it and although it may have improved, it still smokes after idling. I'll check it again tomorrow when I've got light and time to let it get nice and hot... we'll see. If it improves enough to make it not embarrassing it'll be good enough for me!
