I think I overtightened my plugs, thoughts on next steps?

(2002 Chevrolet Silverado 1500)
I think I overtightened my plugs when I replaced them. 2002 Silverado 4.8 Vortec. I used standard ratchet and not a torque. Should I take them out and replace with new torqued properly or let them ride? Haven’t driven the vehicle yet just let it idle about ten minutes. Seems to be running fine but am getting some light smoke out of exhaust. Some is either light white or light blue. Not a lot but seems more than before. Paranoid after reading multiple blogs that removing them might cause damage and just let them go to next change out. I changed PCV valve as well. It was totally clogged.

Don’t worry about the spark plugs - even if over torqued it won’t hurt a thing.... Provided you didn’t hunker down on em like tightening a wheel lug nut.. Pretty sure that’s not the case here.

Spark plugs aren’t related to smoke from exhaust.

Now the new PCV valve may be picking up a trace of oil and sending it through the engine - but still nothing to be concerned about.

IF that problem gets worse - possible oil partially ponding inside valve cover.. That is just a possibility worth mentioning.

Happy motoring!

Some aftermarket PCV valves are junk!

Spring tension incorrect for starters.
