The problem is the following:
I used to have the followings readings before September 9th:
Oil Pressure at start up in the mornings: 70-80 psi
Oil Pressure at idle once engine gets to operational temperature: 15-20 psi
Oil Pressure at WOT (15 boost psi with a 16g turbo): 110-120 psi
Now, in the morning of Monday September 9th I started my engine, I was ready to go to work, but somehting weird happened, my oil pressure gauge blinked twice and then I saw different readings from it since that moment, and the readings goes as follows:
Oil Pressure at start up in the mornings: 120-125 psi
Oil Pressure at idle once engine gets to operational temperature: 28-30 psi
Oil Pressure at WOT (15 boost psi with a 16g turbo): 140-150 psi
I thought my gauge or the sender unit was broken, so I borrowed a mechanical gauge from a friend to test, and the readings are pretty much similar, so my oil pressure gauge seems to be working correctly....
I haven't changed anything in the car, the oil I'm using is 20w50, the Balance Shafts were removed more than a year ago... I'm using a K&N oil filter... I do have an external oil cooler...
Any ideas on why the oil pressure changed suddenly?
