Default Crankcase Pressure

I've read a few old posts about this but didn't find anything new. Oil pressure in my 427 has always been high. I had one of my crankcase ventilation hoses come off on a trip and didn't notice it until I got home. After that, oil pressure seemed to drop back to normal. Can this cause any damage? The hose that came off was the one on the left that connects to the throttle body. This was just after installing the powder coated/ported TB from Bauer (the TB looks great BTW).

Be careful of that high pressure your big engine build up in crankcase, because that can blow some gasket for you. Some people get the oilfiller cap with the airfilter on, I did my own. With a cheap airfilter, I drilled a hole thru the filler cap and push the airfilter rubber hose down in some silicon, and then from other way I push up an PCV, because I don`t want the TB draw air in from an open filter in the filler cap.
