low oil pressure

howzit
the oil pressure in my 89 EA Falcon S 3.9 CFI is low
when you start it up it sits between red(low) and 1 bar
then when you start driving around town it goes up to two bar but if you strat driving hard or cruise on the highway above 70kmh it starts going down
and sits between red(low) and 1 bar again.
if you start going over 110kmh it sits just in the red(low)
could somebody please tell me whats wrong
the head gasket is fine and there doesnt appear to be any oil leaking from any where else
all help greatly appreciated
cheers

Re: low oil pressure

NOrmally it should sit low on the gauge, but not that low, id say it probably is either the sensor isnt tight enough, or (unlikely) your pump has bitten the dust.

Re: low oil pressure

Have you started with the simple things like checking the oil level?

Re: low oil pressure

Number one after checking the level, and as the sender and gauge are electronic in operation, is to connect a reliable pure mechanical gauge to the engine in place of the sender unit. Start the engine and see if you get, at a minimum, 350 kPa or 45 psi (in the old money) at about 2,000 rpm with a warm engine. Only think about hitting the panic button if you don't get something like the above figures. Getting to the sender is a bit of a pain, but it can be made easier by removing the oil filter temporarily.

Yes, it may be the oil pump, but it also may be a blocked filter or a stuck open oil relief valve, and that's a sump off, unfortunately. But try everything else first. Oil pumps don't usually give a lot of trouble.

Re: low oil pressure

Try using better oil also, replace your oil with Penrite HPR30... my pressure was like that and is great now...
