Engine / Oil Problems .. Please Help

umm, i think they use an agent through the engine, they don't just fire the bugger up dry and run it for 20 mins...

My Oil Pressure is 4 normally at idle. Then after really hard driving it goes up to 6. I think it overflowed. I couldn't see very well but I opened the bonnet one night and the little holder just to the left of the right engine bay suspension top. Is this it? If it overflows is this bad?

Whats an ideal Oil Pressure and what should I do? Just let some out? What does the Oil Pressure mean if its high or low anyways?

2.2 at idle(700~800rmp)
