Okay. thanks to Radium King, JFP and 911Monty, My eyes have been opened. YEah, I can see it now... makes total sense. that ALSO leads me to understand what MaxD was getting at, about the engine turning backwards....
y'all are a wealth of knowledge here.
now, excuse me while I back-up a little bit, as I take a long look at the way Porsche engineers designed that entire system, and shake my head in wonder. (as in: I wonder why in hell they still had jobs after that mess?) 
Of course, I've seen worse, because I've owned Jaguars, RangeRovers and Maseratis.  |
In your previous thread, Post #12, I asked if you got the clutch released before going backwards in your spin when I asked about the scavenge pumps. Have you checked their condition? The sources for pressure in these engines come from compression/combustion, thermal/ water, and mechanical/ oil pump. Since you don't have water in the oil there is really only 2 sources you need to evaluate for pressure in the valve covers. The AOS is a source of vacuum not pressure. It is basically a regulator between the intake vacuum and the crankcase.
