Low oilpressure

[robert ylitalo <robert.ylitalo@kiruna.se>]

According to the former owner of my car it has a low oil pressure.
This he has seen when he have revealed the camshaft. He says that it 
should flow oil but know it only comes a little.
How can i verify this and how much oil should there be?
All instrument lights except the ignition lamp turns off when i start 
the car and it runs very well.  
The oil is new and they have gone through the engine, If anything is 
wrong what could that be
