seems to be familiar with these cars, but my baby smokes out the exhaust wicked until it warms and then a bit when i drive. what gives with this? i go through a bunch of oil and i found only one plug goes bad pretty fast. it is oily and mucky looking. it doesn't leave puddles of oil. i know it must be burning it. i just bought this at the end of last year. looking to restore it. i am going to change the valve cover gasket for starters. do i have a bad valve at my bad plug?

Guides.
Shot.
Shut it off, oil drips down 'twixt guide and stem, puddles on the backside of the valve, start it up, gasoline washes it down, combusts, and you've got smoke.
CLASSIC start-up smoke, goes away when warm.
If I had a dollar for every LBC guide I had to have re-done in my career, I'd be livin' in the Bahamas!

Well, if it's bad enough, pull the valve cover, pull the rocker shaft and rockers, then see how much play there is in the valve spring retainer (move the top ends side-to-side and fore-aft).
Seen some so bad they wobbled.
If that's what it appears to be, and start-up, not much else (rings leak residual down when off, away from combustion chamber, etc), pull the head, take it to a machine shop for a teardown, quote, and rebuild.
