Saxo VTS Rocker Cover Oil Breather Problem

[Yop]

Been racking my brains as to why this is happening and can't find the solution or an answer, so hoping you guys could shed some light !

I'm getting massive amounts of oil coming out of the rocker cover breather. I can do 4/6 laps at Cadwell and my catch tank is completely full !

Any suggestions why it's doing this ? As it's doing my head in !

Head gasket issues, exhaust gas pressurising oil

Head gaskets been replaced about 400 miles ago that's the only thing, and not getting any collant/oil mixture. My thoughts are pointing towards the rings. Because evey now and then if you let off from around 6k and roll it down to 3k it puffs out a big cloud of blue smoke, and sometimes when letting off from full throttle. Just want to be certain it's the rings before I dive in and change them

you changed cam box covers to plastic ones?
check that the big breather hole lines up with one in head
do a cylinder leakage check --not compression check
can you feel large pressure coming from breather pipe ? on idle and worse as you rev it ?
