Default Need help 427 low oil pressure ?

Hello All,

I am hoping you guys could guide me with your knownledge and experience.

I have a 427 side oiler that has low oil pressure. I have reading the threads and I see that most of the 427 with HV oil pumps or even standard pumps are running between 60 - 80 psi at idle. I have also come across a thread that this person is running 25 psi.

In my setup I am running 2 oil filters and a armondo oil pan. I am not sure of the oil pump if it is a HV or not. My current pressure reading is 10 - 15 at idle running 10- w30 oil with Motorcraft oil filter. I know this is not normal which is why am seeking advice.

I plan on changing out my oil pump and would like to find out what springs and relief valves I should check or replace. I am running a solid lifter roller cam to keep in mind.

Is there anything else I should check before pulling the pan?

Thanks b
