umm.. my 2 cents.
Have you checked your oil level? I notice that if I put 5L of oil the oil pressure runs high.. but if I put in 4.5L of oil its much lower.. so just wondering

You have oil pressure bleeding out somewhere, I wouldnt be surprised if you start hearing a knocking come soon 
A oil pump over time will create grooves and allow pressure to leak down, but how is sounds
BTW, my car at idle has about 10-15 psi of pressure, and when I rev it goes up to 40-60, but it also knocks alot, spun bearing... HAHAHA
