Fuel smoke and fouled plug

Update #2

New intake gaskets got me up to 14 lbs of vacuum. At my altitude that’s right where it should be.

The smoke is still there, but is now 100% burning oil. First start up there was a slight bit of smoke. Shut it down to take the vacuum gauge of and put the air cleaner on. Started it back up thinking I was going to take it for a drive and had much heavier blue smoke. #8 plug is pitch black, no more shiny to it.

Im almost certain it’s a bad valve seal, unless anyone can think of anything else?
Update 3

Discovered I have Teflon seals. Checked to make sure they were all seated properly. Everything check out. Buddy of mine who builds motors says with these types of seals you’ll always have some oil burning.

I am back to square one though. The smoke and rough idle only come on after the car warms up, maybe 20-30 minutes of driving after 10 minute warm up. I think I’m back to chasing ignition problems. I can’t get the car to accept the vacuum advance either. Hard to start when it’s hot too, like the battery is dying.

My next steps are battery, electronic distributor, and plug wires.

P.s. I’m mostly venting at this point ha ha!
Maybe I missed this early on but what are you running for a PCV system?
