I have a heads and cam L76 in a G8 GT. I have a high volume oil pump that is 6 months old. I changed the pressure sensor so its not the problem. I checked the HP tuners and it said it's at 25 psi at idle when you rev it its at a good pressure. Has anyone else had this problem? What's going on what should I do?

My cammed L76 would idle at 35 psi on start up but when warmed up would run around 25 psi too. I never had a problem with it.

What was your pressure before you changed the oil pump? 25psi at hot idle is fine as long as it increases with rpm.

I never checked pressure before I did the after market oil pump.

25psi at idle doesn't seem that low. What is your idle set at? Most guys I've seen are between 25-32psi. Mine is pretty high with the Melling high volume. Idles around 35-40psi when warm.

Edit: What bypass spring do you have installed? I'm assuming it's a melling pump.
