A little blow-by? 120-130 1967

The odo says 90K and appears to be correct, not 190K miles.

The flame trap vent hose goes to atmosphere, and the carb to filler cap is soaked with oil. I want to take off the flame trap, but need instructions. I don't see any screws on the B18.

The hose to atmosphere is probably because there is a little blow-by at the rings. Now, this poor car hasn't been run much in the last 5-6 years and I wonder if some of the rings are just stuck. Would a soaking in Marvel Mystery Oil help? Should I even do it? I plan to be gone for the weekend and could let the MMO just sit for 4-5 days.

I will be putting in new plugs, one of the old ones gapped out at .035+ because of a lot of wear. All 4 plugs came out coated white after a 15 mile highway run.

The engine does 'sputter', regardless of timing setting. I will have to borrow a compression tester to figure things out. I hope it is not a bad valve.
