I usually run around 75 psi at around 4K rpm
last month this dropped down to 60-65

Usually this is a sign of rod bearings in the y8 (past experience)
However I replaced the rod bearings, and still am getting this low reading, directly afterwards

Could this be a sign of even bigger problems?

You getting 50psi at 3k?
What's your idle PSI?

Around 25....which is not low

I guess I am used to higher pressures...and not I may be getting "normal" pressure

would a leak cause this problem? my car was running low psi and i changed my oil pan gasket recently and now its fine.

Crazydave

have you changed the oil lately, are you using the same grade,
also how hot was the oil?

Fresh oil, same grade as always

Oil was as hot as it gets when car is fully warm...actual temperature not known

Point is, 2 months ago with this same scenario, I would get 15 psi higher readings on average

My oil pressure dropped about 5 psi in the past few months, but its also been warming up outside... The hotter the weather gets your oil pressure will drop a bit.

Crazydave

Also the harder you drive the car, the lower the pressure will go,

When I was on the track I would drop from 75 psi to around 45 or 50!
I had to stop and it cool off for a while, and I should have changed oil grade.

I agree, but last august when I was running same grade oil, I had 100 psi at startup, and a constant 75

Its not oil grade...its not the heat...there is more going on...and I will find out what it is!

Im running a turbo y8 and my guage at first start up is like 80-85psi.. After running it and then idle is around 9psi.. Cruzing at a normal 65mph its like 65psi.. Let off the gas and its around 46psi..Under boost load at WOT its like 85+.... I hope Im ok too..

Well I tried some 10W30 last night, helped a bit. Temporary fix to a bigger problem I guess
