That's a good start. Thre is also an oil trap, under the intake
manifold- a balck, plastic box sot of thing. Cheap to replace, hard to
clean, and they can become clogged which will/can also cause leakage.
Again, as I mentioned, check for negative pressure in the crankcase
when the motor is running. If there is negative pressure, then the
things I mentioned are not the problem.

Take a bright light and look into the valve cover through the oil fill
cap. Also, make a probe (a bicycle spoke might work) and "scrape" off
the bottom, inside of the oil pan and see what comes out. it will give
you an idea of the amount of crud in there.
The problem is that when this stuff is excessive it is a sign that
other things are wrong- it's not the crud that is the problem, but
what caused it to accumulate.
Try that cleaner- I don't think it can make things a whole lot worse,
but FIRST try the crankcase pressure/vacuum check:
-Take a piece of stiff plastic (like 3-5mm thick, clear plexiglas).
-Moisten one side with a thin coat of engine oil.
-Remove oil fill cap and lay plastic on opening of valve cover.
-Hold in place lightly. Look at oil film to assure that a good seal
has been achieved.
-Lift plastic off. Remember how much force it took to lift.
-Replace Plastic, hold in place, and have someone start motor.
-Hold plastic place lightly for about ten or fifteen seconds. Look at
oil film to assure that a good seal has been achieved.
-Lift plastic off. It should take more effort to remove than it did
with the motor off.
