Low oil pressure and what to do?

Low oil pressure and what to do?
what causes the oil pressure to drop intermittently when engine is warm? It is between 1800-2100 & 2700-3000 and if throttle is blipped the pressure increases and the buzzer and light goes out.

RE: Low oil pressure and what to do?
Sounds like a blockage in the pick up or a stuck relief valve

I may be a mechanic, but i can't fix stupid

The buzzer should only go out ( once it is buzzing) if you turn you ignition of and then on again.
I thing you need to do a mechanical pressure test to confirm weather it is oil pressure or an elec fault.

I have had similar issues on my playbus, changed the oil to shell helix and the problem went away

the 5 cylinders need a thicker oil but you can add wims charge to thicken up your existing oil and see if it sorts the problem

castrol gtx is not good for 5 cylinder engines

I was also in believe that the oil maybe at fault, but also heard. as above that the pressure relief valve may be at fault.
Wich Helix (hx5-mineral. or hx7-synthetic) and what grade?

RE: Low oil pressure and what to do?
Thankful for the advice. added about 850ml of Wines charge and made a big difference. Still gets buzzer etc but less and pressure is higher when hot. Will do the oil change and should sort it all I believe.

RE: Low oil pressure and what to do?
bennie, not to sound funny, but a newly rebuilt motor should not need thicker oil, should run fine on 20 w 50, i would talk to the rebuilder again, maybe they have the senders connected incorrectly, or i would try new senders as well.
