This is my first post after my introduction post (and there will be a lot more FE related questions...)

My 390 FE is leaking a lot of oil. Now someone told me that if the pcv is not operating properly, the presure inside the crankcase is working the oil out via old seals and gaskets... Is this true?
Can I test the PVC?
If it's broke, vcan I delete or bypase the PVC.
Thanx
