Default Valve Cover Gasket

Have been seeing drops of oil when I park my 95 D21 four-cylinder. Decided today that I would investigate where the leak originates. Have read a bunch of articles that itís best to work your way down from the top. Story of my life.
The first thing I noticed was the valve cover gasket that seem to be heavily covered in oil. Not sure why I didnít really notice this when I did the tuneup.
So it looks as if this might be part of the problem since all Iím getting is a few drops here and there. At least I think it needs to be replaced. What do you all think?
It looks to be a pretty straightforward job and I want to use Fel-Pro gasket but the question that seems to keep coming up is whether or not to use a sealer or not. The Fel-Pro directions say not to. So again what do you all think? Iíve included some pictures to get a better idea of how much of a leak I have.
I have done some mechanical work on the truck since getting it in August but this will be the first time Iíve opened it up to see the internal workings. Any advice is truly appreciated. Doís and doníts ? What else to look for while Iím doing this.

It's pretty straightforward, just take the valve cover off and put the new gasket in then put it back on. There are a couple of bolts on the intake side that hold in brackets for the wiring harness. They are really hard to see but a 1/4 drive socket and an extension should be able to get it. Don't forget about the half-moon plugs, they should come with the new gasket.

A fel-pro one should be fine. I am actually running the one that came in my cheapo engine gasket kit I bought. It hasn't started leaking yet .

felpro sucks ass. they rarely fit imports properly. use a little rtv to help seal it nicely around the whole lip

Fel-Pro gaskets have always worked great for me, over too many decades to admit ...

Being old-school, I use Permatex #2 gasket sealer (unless something else, or nothing, is called for) -- the olive green goo that "never hardens." I often find it at parts swap meets for $1 a tube. I think another company makes it now.

I dunno about the ka covers, but the z24 was horrible for leaks, so I sealed the shit outta mine.

What about all the Crud/Oil on the engine and around the cover ? Can I use brake cleaner? What? I really don’t want to hose it down with water afterwards.

get soem castrol super clean and put it in a spray bottle. spray liberally.

take a soft brush to anything that does run off on its own. then hose it off. or use a cup of water to strategically rinse it.

I've always had good luck with Fel-Pro gaskets. I used them pretty well exclusively when I did my timing chain. The only gasket that has not been replaced from original on my KA is the rear main. Street_ruler is the first person I've heard of having a bad experience.

Not sure what the torque specs are, but figure those out and torque it to spec. Make sure you torque across from yourself, like torquing a wheel. That way you'll gently tighten it down evenly, and not pinch one side first.
