engine smoke from oil fill?
I have a 223. I put it in a few weeks ago and got it running. Prior to this it was not started for 3 years(supposedly), it was not run on the road for at least the last 10-12 years or longer. The guy said he did start it in the driveway and let it run occasionaly. After I run the engine for 5-10 minutes you can see some minor smoke coming from the oil fill cap/post. Its not road worthy yet, no brakes so I only start it a few times a week myself. Is this common or a sign of something that needs to be replaced. the engine is not even really warm yet when it happens, you can still touch the engine with your hand.
Thanks in advance for any advice.

What year truck?
61 and 62 have a road draft tube to help pull the blow buy out only when the truck is moving.
63 and 64 has a cone check type PCV valve piped to the intake. and creating a negative condition in the crankcase.
It is normal to see it with the road draft type

Well,
Don't form any condemnation yet until you get it road worthy. Once you get a few road miles on her, it may clear up. Right off it sounds like blow-by. (wear on the rings). If it has a PCV valve, be sure it's clear and able to draw a vacuum.
I think the best thing you can do now is to get her out on the road and make her feel wanted.

That seems unusual to me. I have a '63 F100 223 and it has a PCV valve, although it is a factory adaptation to the opening in the side of the block used in earlier models for the draft tube.
It's possible my truck came from California where tightened emission standards began in those days.

Look in your vin number the fourth letter will be the point of manufacture.
I had sitting side by side two 63 trucks in the yard one time.
One built in California and sold in Oregon
and one in New Jersey sold in Pennsylvania.
California had the PVC cone system tied into the base of the carb
New Jersey had a road draft tube.
Bolth were built within a month of each other.

my own '64 had road draft. The vapors you're seeing are not at all unusual. Actually, a pvc system would make for a kinder environment to your engine innards. There's moisture and corrosives in what you're seeing escape. Good to get that stuff outta there. PCV is a great improvement over road draft tube in that regard.
That said and based on my rather obsessive research, '64's originally came in a mixture of pcv and road draft. I'm sure '63's did as well.
