trying to quit smoking
Well, I just got a 66 chevy truck running that has been setting for several years. It has a 283 and 103,000 origional miles. All I have done so far is new points, plugs, and an oil change. The thing smokes a bit and I was curious if there were any good additives out there to put in the oil or gas to remedy this problem. Other than that it runs great and just has a slight valve train noise (can barely hear it). Thanks

Does it smoke all the time, or just upon initial start up?

smokes a little
Well, I'd install new valve stem seals and while I was at it I would have the valves ground and new springs installed and new valve guides. Then I would pull all those old rings and install new rings all round. While I was at It I would install new main and rod bearings and a new oil pump and timing chain. But Thats just me. Or live with a little smoke?? Did you happen to check the compression? How do the plugs look?

There are several additaves (Z-max, valvoline high mileage) you can use, and some may make your truck smoke less, but from the experience that I have had with those, they work well for a while, and then they quit working and the car is worse than it ever was. If it was me, I would try to live with it, and when you get enough money saved up, rebuild the motor. You could just get the valve guides done, but if the rings are bad, that will not help. If it is only your valve guides, then your truck will smoke right when you start it, and then quit. If it smokes all the time, I would guess it is the rings.
good luck, Adam

You said that you just got it started. I would run it for a while. it might stop on its own, once things wear in a bit.....just my thoughts.

I'm with Poncho52, drive it for a few months see if anything changes. My dad got a low millage 78 nova that had been sitting for years. It smoked when drove it but after about 3 months of daily driving it stopped smoking all together.

I will second the vote for Lucas Oil additive. I had smoking coming from my #1 cylinder and a little from my #3. Put this stuff in when I did an oil change and 4 months later and still nothing. It will depend on how bad you smoke. Bad smoking is usually more of a ring problem unless all your stem seals are going out. In my experience a slight smoke or startup smoke originates from oil coming in through the valve seals.
However as mentioned before the only true fix is to rebuild/recondition the heads (and re-ring it if nessesary).
