I know these old cars smoke but is there an additive or something I can do to stop the smoke? It's not bad but if there is a fix then I'd rather have no smoke.

What kind of smoke?? Blackish over rich combustion smoke, or blueish/white oil smoke, or whitish anti freeze smoke?? They ALL have different smells, IF you are familiar with them. Also, is it at an idle, or on acceleration or on deceleration or when you stab the throttle, AFTER a long decelleration? OR is it that stinky-poo belching out of the oil filler? Jut the facts, we just need to know the facts!!---Bill W.
(Chief had one, where rats/mice filled the headpipe with Hickory Nuts, while it was disconnected, they couldn't get past the muffler baffles & just laid in there, SMOLDERING for days! They emitted a "woodie" type smell. If it's just mouse nest stuff, it should burn up in a few days & go away. I don't know what burning mouse poop smells like!)

i think worn valve guides can smoke a little too. i saw an engine at the dump where someone had put little O rings over the valve stems on the spring side to try and keep the oil out but IDK if it helped.

I'll drive it later today but it seems to be a light white color at idle.

At idle if it's more bluish in color and doesn't dissipate all that quickly then it's usually the valve guides and burning oil..

If it's light white and it dissipates somewhat quickly then it's most likely water getting into the combustion chamber. Could be anything from a head gasket to a cracked block. This would be seen either at idle or while driving.

If it's blue smoke while accelerating then that usually indicates piston rings.

Not meant to be the exact answer but a troubleshooting guide. Compression tests and a vacuum gauge can help to aim you in the right direction.

Good luck.
