Not 100% on this but I would pull the plugs and compare them to [http://www.hioutput.com/tech/plug.html These Images].
But it sounds like your van is misfiring and the lose of oil pressure could indicate several things like worn bores/piston rings or valve guides. Good Luck and Remember.
Change Your Mind, Not Your Oil.
Use the First In Synthetic Motor Oil's.

A pressure trigger is a trigger for initiating assisted ventilation. A pressure trigger consists of a measuring pressure and starting assisted ventilation when the pressure reaches the desired level.
Only if you haveherpessimplex virus already in you or on your hands
When it fires with very little pressure on the trigger.
Called 'trigger; finger. Surgery is one way ........and it might just go away.
Guards the trigger against accidental pressure, and reduces the chance of an accidental firing of the gun.
Migraines are triggered by things that change the physiology of the body. Anything that can create changes within the body may trigger a Migraine. Barometric pressure that is too high may create changes that trigger a Migraine attack for some patients. For others a low pressure may trigger the attack. Still others are triggered by the change of pressure.
Atmospheric pressure changes can trigger Migraine in some patients.
A mechanical breath delivered by the ventilator can be initiated either through a detected change in the flow in the circuit, or a detected negative pressure (so flow trigger or pressure trigger)
it should produce a trigger pulse at a time.
Automatic-rifle bullet are usually gas powered and the achieve great speeds by rapidly accelerating out of the rifle, usually in response to a trigger.
Baroreceptors
try looking at the pressure gauge on the side of the trigger body
