PCV- Good or bad idea for a performance engine?

Well Hello!!!:cheers:

Got a chance to start checking the motor today - , and found that my PCV valve is pretty much toast - glued up and "gunked"

Would I be right in thinking this may be causing my increased oil burning??
(Im guessing it is - crankcase pressure forcing vapour past the rings into the chambers?)

Also, my front seal has been seeping a little over the last few weeks......Reckon I found the culprit?
