Bought a jeep willys to restore/fix up, whatever. It has the flat head four cylinder 134ci and new carb, it runs pretty good but tons of white smoke from the exaust. I tried some marvile mystery oil, let it sit in each cylinder for an hour or so then blew it all out and started it up again hoping if it was a stuck ring or rings etc. Any help greatly appreciated.
White smoke usually means water. The muffler can be full of water that will take a while to steam away or you could have a head gasket issue.

So if it's not water in the muffler then we are talking a cracked head/block or blown head gasket right? How do I tell which is my problem?
I'd recommend asking around on the Willys tech list,

Blue smoke means oil. White smoke means steam, so you may have a cracked head gasket. Before you pull the head, you might try some stop leak. If the steam stops, then you'll know that was the problem. If the leak is too bad, water will get into the oil and can destroy the main bearings.
Have fun restoring that Jeep. A friend gave me a '61 Kaiser Willys CJ5 with a Koenig body. It sat under a tree for ten years. I'm restoring it now.
Thousands of those flatheads are in service on sailboats as auxilliaries: known as the Atomic Four. =20 Few crack.
Thousands more live on as forklift engines.
Continental built many, Graham used Continentals along with a lot of others. I have 4 uncracked Contiental 6 heads in the garage, one is aluminum. The straight eight was more prone to cracks in the deck than the head. Back on topic, a 4 cyl flatthead should take about 15 minutes to remove. Once you have each head nut about flush with the top of the threads, wd-40 the studs and lightly tap each sideways front and side, to free them in the bores to help get the head up over them, then finish removing the nuts. Never re-use a head gasket, even the solid copper kind.
Maybe true of the Willy's Marine engines, but Grey Marine? Thousands.
