oil leak from breather hose..... how do i fix it???

when i get on it over 3000 rpm i get a wicked oil leek from the grommet that holds the breather hose from the passenger side rocker cover to the throttelbody. the vacume is so strong that i get oil in the throttlebody. is that normal? i can lose like a 1/2 quart if i really stay in it.by the way it has a wicked oil pump in it 60 psi when cold 55 psi when warm under full throttle.the pcv valve in the other cover is fine. also if i pull the dipstick out there is a little bit of air coming out of the dip stick tube btween 1000rpm to 1500 then i goes completely away all the way up to full throttle.is this normal? the car runs great and idles steady at 700rpm and it just gave me 22 mpg on a road trip...what u think? sorry so long

You get air out of the dipstick tube, but only at low RPM's? That's strange. You sure the PCV valve is good?

Any air coming out of the oil filler hole on the valve cover?

yeah the same happens from the oil fill cap on the drivers side but above 1500 it all goes away...i thought i had piston blow by.. but a reputable shop hooked me up to a scanner and checked it out and the car to him was running imaculate...21 mpg shows me that he pretty accurate.but the oil leak from the breather hose is pissin me off .the pcv rattles when i shake it does that mean it is ok it is only a year old.

Yeah, they're supposed to rattle, and snap when you plug the end (engine running).

That's a weird one. Any engine I've seen with pressure in the crankcase always made more pressure the higher the RPMs went and could be tracked to blowby.

i also noticed that after i accelerate to like 4k rpms then let off quickly the pipes puff a small amount of blue smoke but it dousnt do it on acceleration , only when i let off suddenly..i am gonna do a compression check on each cylinder in the mornin.hmm valve seals? maybe needs a valve job? would that account for the air in the pan and under the valve covers?
