oil in spark plugs tube and oil leak out of engine

all the oil leak out of engine after a oil change? and i have oil in the spark plug tubes

Oil in the spark plug tubes is common. Replace the valve cover gaskets and soak up as much as the oil as you can out of the tubes with rags. Not a bad time to replace the plugs and possibly the wires (might be bloated from soaking in oil.

As far as the oil leaking after the oil change. Make sure you didn't "double gasket" the oil filter. If the old gasket from the old filter stuck to the block it will cause an oil leak when you spin on the new filter.

93' 2.2L had the back two valve cover nuts not even hand tight. 3 spark plug tubes filled up with oil. 2 center wires had rubber expand many, many times their original size and forced them out of the tubes. Took out the plugs and #3 had definitely not been firing for a long time. (Son that refused to learn about cars has been driving it all winter and spring) So I figure with those two wires popped out and #1 also full of oil he was running on two and sometimes one cylinder. Good job for that car. I took off valve cover, cleaned out tubes, replaced plugs and wires and got a gasket set that I put sealant in the four angled corners of the large gasket. Anyway, what I was wondering is, what is recommended for the valve cover nuts to keep them from coming loose? They are as tight as I feel I can go without causing damage. Should I just check them every 3 months? Should I use some type of locktite?

Valve cover gasket has nothing to do with the tube leak.

That is correct!! Replacing the VC gasket will not fix your problem at all.

You need to take off the rocker arm assy, there is a set of rubber gasket there. Normally the tube leaks oil from there.

Get ready for valve lash adjustment.

One month since I changed my valve cover gaskets, including the ones that seal at the spark plug tubes. I pulled each plug wire and no oil in any tube. I'll continue monthly checks.

If you replace the seals under the rocker arm, you should be good for another 7 years.
