I have said it before and will say it again. The pcv vavle sticking will cause loss of oil. I have lost 2 quarts in a short period of time. if not checked it will cause engine failure due to not enough oil. I have removed my pcv valve and put in a breather and plugged the intake line and have fixed my oil lose problem. Before I decided to remove the pcv valve I had replaced it ,this was not enough a few weeks later I had oil loss again. That is when I decided to remove the pcv valve and my problem was solved.

Sorry Jolly Roger VX, missed your post . shawn
