Rb20 Oil Pressure

[rb20bmw]

hey guys i have an rb20det in a bmw. the problem i'm having is that i have a lowish oil pressure. I am running a remote oil cooler and filter. has anyone had experience with this dropping oil presure? at idle its sits at around 10psi mesured from the remote filter and on revs it reachs 20 psi. any help appreciated

I just finsihed rebuilding mine and oil pressure when cold sits up around 60 - 70psi measured on the HKS sandwich plate.

as in on the plate that replaces the filter for the relocation kit?

has it got a thermostat on the relocator? check your flow direction to on the lines.

[rb20bmw]

no there is no thermostat on the relocation kit. i'm pretty sure the lines are correct. is the centre line from the plate on the block the pressure line? asin the one that would normally flow into the centre of the filter

What filter are you using with the relocator, Z145a etc?

Might be worth putting as much oil as you can fit into the lines, and remove the CAS and crank it to get pressure up.

its a z30 filter. there is oil flow through the cooler cause i can feel it getting warm. the lines enter the cooler from the bottom is that a problem?

anyone got an ideas i dont wanna pull the motor out just yet

Yea I have two guages one in the factory position and one in the plate that goes where the oil filter normaly goes both read pretty much the same.

Does the guage stay steady or does it pulse? how much oil did you put in the sump?

[STATUS]

oil flows out the side hole and back to the engine via the centre. (retainer thread) but if cooler is getting hot then it is flowing.

[rb20bmw]

well the engine is going in for a bottom end rebuild. the sump holds around 10 litres as its custom to suit the conversion and with 3 litres in the sump the pickup is still under the oil. goona make a new custom pickup using speed flow fittings so there is no chance of a leak from it anymore. i think the pick up is what caused it in hte first place
