Rubber piece at the front of cylinder head

[sr20dorifto]

Hey, all. I've searched and searched and can't really find the solution.

I have a '91 fastback with a KA24DE. Recently, I looked under the hood.. routine check for everything under there. I saw oil and dirt built up all over the cover on the top of the motor. It looks like the oil is coming from those rubber pieces at the front of the cylinder head. Sorry I don't have any pics to clarify, but they are the ones shaped in half circles. They are just hanging halfway out of the head. How can I fix those? Where can I find replacement parts if need be?

Thanks in advance for everyone's help.

Edit: Here's a pic of the parts I'm talking about. Not from my motor, but i've circled the rubber parts.

You need a new valve cover gasket...

You don't really need this next piece, but it's recommended by Factory service manual to put below the half-moons. Just clean off the gunk that's there, torque it down (think it's about 10-12ft/lbs, just a lil more than finger tite) & you should be good.

Awesome!! Thanks!! I can pick one of those up tomorrow. I just wasn't sure if those were separate pieces. I already have a tube of gasket maker as well, so I'm covered there. So it looks like my Saturday will be spent fixing that and the oil pan.
