Oil supply/pressure question on 2.4 stroker

[TurboTims]

So I built a long rod 2.4 motor and my oil pressure goes up with RPM but once I get way up in the revs, like 6k, the oil pressure starts to drop. When I built the motor I had to plug a whole bunch of oil returns in the motor where the 2.0 head bolts to the 2.4 block. Well what I am wondering is, am I sucking all the oil out of the pan and is it getting stuck in the top of my head or does anyone have any idea why my oil pressure would drop with RPM? How are other people dealing with the fact that there isnt as much routes for oil to get back into pan or is there something else going on with my motor. I run 20/50 royal purple if that matters. Sorry this is posted in newb section but I just dont post online enough.

I can't say how effective it is as I haven't had your issue before but do you have the kiggly hla regulator up in the head?

Which 2.4 block are you using? I've had no oil pressure problems with my builds. Did you use a new OEM front cover?

What motor do you have, 4g64 (7 bolt), 4g64 6 bolt (G4cs), Galant 4g64, Also What holes exactly did you plug, What Head gasket did you used.

More info is required to give a better answer.

HOw far does it fall? they should plain out at some point because of the oil relief port opening enough to stabilize the pressure

2.4 block out of a 7 bolt galant. 2.0 headgasket. Plugged holes that gasket didnt match up with. No I dont have this kiggly oil pressure thingy ma jiggy. Oil falls to around the middle of the gauge. Its more then its at when its idling but less then it is at around 4-5k

If you can't find a solution otherwise you may want to give the Kiggly HLA regulator a shot. It limits the oil pressure to the head with the idea that it will keep the rest of your oil down below. Here's a link:

You also need an aftermarket gauge instead of using the stock one to know exactly where your oil pressure is at.
