Excessive Crankcase pressure - G35

[Higgs1]

I have a friend with an 03 G35 coupe. It has excessive crankcase pressure when you pull the dipstick or oil fill cap.

I replaced the pcv on the passenger side front valve cover and the problem continues.

Do these cars have multiple valves in the pcv circuit? Has anybod had this issue before? I haven't done a compression check yet based on the fact the car has 40K, but if there arent any other areas to check I will do that next.

Any help would be appreciated.
