Just went out and looked at a couple more things... I pulled the PCV
valve hose off and I have good strong vaccum there... plugging the PCV
valve nipple on the valve cover, and with the oil filler cap removed...
theres pressure puffing from the oil filler cap hole in the valve cover.
With what is either smoke and/or vapor visible. With the PVC valve
hose reattatched - I can still feel pressure from the oil filler hole.
Not good...
