Crankcase valve leak

I noticed today that there was an accumulation of oil around the crankcase valve (or whatever you wanna call it) towards the front of the engine. When I wiggled it around I could see a little oil kind of seperate in between the lips of it.

Here is a pic of what i am talking about:

Is this normal? If not how do I fix it and what has caused it?

i have the same issue, except mine is starting to throw out quite a bit of oil. I was told to grab the piece and pull it out of the valve cover ... then put a new one in. However, it simply won't go. I could use a screwdriver or something, but want to confirm it really is supposed to just pop out of there???

Those are for crankcase gas ventilation. A little oil is okay but not too much. Pull the hose off the elbow and see if it is clean inside. You can also pull the elbow out with a good tug.

Here is some info about the Crankcase Valve (CCV)

What does it matter if it is clean inside?

If you just replace the elbow will it stop the seepage?

The rubber part in the valve cover gets hard over time and looses its ability to seal so it leaks. Yea if it's too bad then replace it.

Or just put an "O" ring under it. Did that 5 years ago and it hasn't leaked yet...
