Gaskets leak after many years!!!
First, try snugging them down. Try using just a spintite - nutdriver and a firm twist is enough. Do not crank em down with your ratchet , the covers bend and distort, causing worse leaks if overtightened. Looking up the torque spec would be advisable... but a very firm twist of the wrist is usually just right.
This will fix your leaks about half the time. Totally fixed, it will not drip at all!
Yeah, the other half of the time you need to put in new gaskets, still a small job and inexpensive.
I have never had to replace a pan gasket (just for oil leaks) but have had a couple get so loose that the pan bolts could be turned with your fingers!!
On a vacation about 30 years ago our car suddenly began taking a qt of oil every tank of gas. Wow, thought we were in trouble but a couple of days later I saw a big puddle at our campsite.... the pan bolts had become so loose the pan could be rattled up and down!!! A few minutes under the car and it returned to no drips and no oil consumption at all!
Good luck!
