It looks like it unhooked itself a while ago. The end of the cable actually wore away at the slot for the valve so I need a new valve. The end of the cable still looks fine to me. Middle PV looks fine. I am going to replace the head gaskets (I think there is 2) in the cyilinder to make sure. Not sure how else to fix the milky oil on the PV.unfortunately milky oil is usually a sign of moisture. you may have an issue with the head gasket o ring. best case is condensation and buildup from not working properly.
as for the unattached pv, is the cable pulled out of the slot and obviously doesnt look right? or was it simply unhooked? you can have it repaired cheaper than buying a new one. was it stuck in the housing? whats the middle cylinder pv look like?
stuck valves or mis adjusted valves are the leading cause for pull throughs.
