My GSR was recently rebuilt was running fine, until the oil light started to take a very long time to go off then i start the car. My friend told me that it may be my oil pump goin back. So i bought a Brand new Type-R pump and installed, change all the bearings once again.

Did all of that last night, put the engine back in the car started it, turned the key to build oil pressure, and the light took a whil to go off. it looked at the oil pressure gauge and it was reading 35-40 psi and when i rev the motor it wouldnt increase.

so i left the car by friend who is a mechanic when he went and check the car he started it and the oil light once again took for ever to go off.

I really would like to know what else would cause my engine to have low oil pressure readings, and cause these problems.

Almost everything in the motor has been change ( ordered new in the rebuild) . it doesnt smoke not overheat.

Any suggestions please.

 

clogged oil pick up possiblely?

 

make sure the guage is working good and go by that,and not the dummy light. also was you bearing clearances checked? thats where your oil psi comes from
