When you swap a P-pump onto a 24 valve it seems to cause a lot of extra crankcase pressure, probably because the p7100 is lubricated by oil where the VP44 is not. Also I think the P7100 returns oil right close to where the 24 valve breather is on the front case, so that's another thing to think about. Some guys say to ditch the 24 valve breather and get a 12 valve tappet cover since that's where the breather is located on a 12 valve. You'll probably still need the valve cover breather to help relieve the pressure.
