Does anyone know what this is. I replaced the valve cover gasket and the oil fill cap, but oil is still running out underneath the cap. There has to be a block farther down that is keeping it pushed back up. Any ideas would be awesome!
Thanks Chris

It sounds like your crankcase is not vented. The flame-trap is supposed to be serviced regularly.
The Volvo doesn't have a PCV valve by definition, but has a flame trap (Volvo's equivalent). This needs to be replaced and the fitting cleaned. There is also a small diameter vacuum hose which needs to be clear. Replacing is normally easier than cleaning it out. Make sure the brass fitting on the intake manifold end of the hose is clear also. If any of these are plugged, you can develop chronic oil leaks plus the fact the throttle housing will get dirties sooner.

Stephen Henning's response is right on the money. My 760T doesn't have a flame trap but the air/oil separator plugged on the freeway. I coated my engine compartment with about 2 quarts of oil from the dipstick tube by the time I reached the next off-ramp.

Your flame trap is clogged, I'm surprised it hasn't blown out the rest of the oil seals by now.
I've also seen the tabs on the oil cap that hold it to the valve cover bent enough that it's not held down tight enough.
Also the rubber gasket on the oil cap can disintegrate or get ripped and fall off.
