Paul,
OH NO. My mistake!
The crank case ventilation is routed through two breather hoses. One of them is connected to the vent port (engine block) and routed up to that "contraption" called "port" (larger one) on the intake man. Then, I believe they just loop it through that piece of PVC or high temp plastic to come out on a smaller port (broken off), I guess they have some sort of venturi inside, that connects to a smaller/shorter hose. This hose connects to the intake manifold ( bottom metal ) The hose is capped at the intake manifold and any pressure inside the crankcase can still escape, well,

to the environment. Also, this is not a permanent fix. On Monday, I will attack this part to restore the correct path. I just did replace a suspension control arm the other day and had put lower priority to this. Aside, I was awaiting the pintle caps from the injector re-man, since the ones that came with them, were too soft and fell off the end of the injector(s). So, I could do the works while I had the fuel rail off and with just a few more bolts take the intake manifold out too.

"Nope, don't want to pressurize the crankcase", this thing is leaking already enough!
Basically, it was just a test to prove the theory!
Plus, all prior work done (headache works/patches etc) on this vehicle was not done by me, I bought it last year and am catching slowly up, with years of neglect.
