Blue Smoke after Changing Spark Plugs?

[GumbyJarvis]

So changed em today, and new wires.

Afterwards and for the 3 mins I let it idle and drove around the yard, blue smoke was coming out of tail pipe

though there was a MINIMAL amount of oil on the old plugs, will this go away?

Blue smoke on start up usually means valve seals

Blue smoke while running, bad rings

The thing is, it just happened after changing plugs, and there was SOME oil on the old plugs that fell into the cylinders...

Is this an engine where the plugs sit down in tubes within the valvecover? If so, its possible that each plug dropped a fair bit of oil (leaked into the tubes) into the cylinder when you pulled it out. That'll smoke blue for a surprisingly long time (minutes).

Valve cover leak, removed plugs let the oil down into the combustion chamber.

Yeah, went on a backroad for about 10 minutes, going 60-90mph, no more smoke, this is going to be fun, valve cover leak gahh!
