Default Oil all over the Valve cover, WTF

I'm trying to figure out why there is oil all over my vc. It's a B-series. Idk why but it looks like its coming from the 4 inner seals that hold it down. They are tightened all the way. And then some is coming from the oil cap area to but thats down all the way!

killin me please help

Check whether the PCV valve is stuck closed.

Is blue smoke coming from the exhaust?

I bought new ones from Honda but I'm still getting the same problem.

Not tight at all. But how would that cause it?

Excess pressure is somehow building up under the valve cover - the PCV is possibly unable to ventilate properly.

Yeah, I think it may be similar to the B16. Sorry, I don't have the B18C diagram.

So all I have to do is squeeze this and I should hear a knocking sound by the PCV?

If you have one of those little mini air filters on the PCV system, thats where its probably coming from. Some oil comes through there... You should also have oil on the underside of your hood, and a puddle right underneath where the filter sits.

Oil coming through the filter? You can see the oil coming from the black seals on the inside of the VC....

Didnt see that. Make sure they are seated inside properly...

I just read that you had oil on the VC, and that you had one of thsoe filters. When i had one on I had oil coming through hitting the hood, and getting on the valve cover.

A clogged PCV can lead to increased crankcase pressure.

Isn't the PCV the black box under the IM? How much does one of them go for?

Check whether the breather filter is clogged with oil. The PCV should be an elbow-shaped metal tubing with a valve inside.
