Best to take a pic of the engine and compare...
Here's one that doesn't leak - yet...
There are several hoses that go to that engine...
The obvious one is on the top valve cover - that heads off to the air box (Air filter) - it's the other half of the PCV valve breather - it takes in air to equalize pressure inside the engine - that valve cover is only supposed to keep fumes from escaping and oil leaking out.
So, if oil is leaking out - two things cause this...
Poor gaskets - old ones - they do fail causing leaks.
OR PCV valve - lost vacuum - doesn't pull fumes from the engine anymore.
So for oil to leak from the valve cover - means the valve gasket is blown - that valve cover gasket - not the cylinder head gasket.
Means the top of the motor has to be cleared off to get at the cover.
But before you do that, do some easy checks so you won't be having to repeat this whole process.
See the PCV valve hose in the "Gap" between cylinders 2 and 3 intake manifold?
That PCV valve is an assembly, a cover that bolts to the side of the motor, and the PCV valve itself rests in it. A hose of 7/8" diameter routes off of it to the intake manifold. and draws vacuum all the time. The hose is rubber - so it does flex an as it ages, can collapse. Caused from vacuum overcoming the resiliency of it to maintain shape and allow air to get sucked into the motor, instead it gets pinched off closed completely and never ventilates.
The PCV routes air - FROM the Air Cleaner (Airbox) thru that upper hose - thru the crankcase - into the PCV valve then into the intake manifold - so it's an Air quality - Idle Quality "hit" that the engine uses to maintain Idle speed and mixture to keep the system running
What it (PCV) does is help sort out oil and the splash and spray from the fumes and air that goes bad from combustible by products. But let's those fumes that would otherwise collect and do damage in there - get purged in a vent to the intake it's why it's called Positive Crankcase Ventilation Valve - it purposely causes a negative vacuum pressure in there to PREVENT the fumes from collecting and generating a
positive pressure - blowing the seals.
IF you didn't have the PCV valve in there - you would have lost the motor a long time ago from excessive blow-by pressures building pressure in this system until it finally popped and oil fumes and the stench of burning oil leaked out.
So, in some ways, you're accomplishing what other carmakers used to do, the older cars provide a tube for that crankcase vapor to escape to the outside - making a messy smell for others to follow. You just don't have that tube.
You'll have some work to do.
Take off the Valve cover, and the Intake Manifold - so that means a tear down of most of the top of the motor to replace those seals. It's time consuming and physical work - not a simple job - lots of steps to it.
