I have a 96 olds ciera 3100 3.1l sfi the heads are starving for oil it makes a lot of valve noise and it had about 20lbs pressure so I pulled the motor and replaced the oil pump and cleaned a lot of sludge out of the pan after I put new oil in and cranked it it still has the noise and only 5lbs pressure I put a bottle of engine flush in it and ran it for 5 mins like it said the noise stopped but still no pressure I drained and refilled it with 10w 40 noise is back still 5lbs pressure what else could it be? thanks

I know its one big big pain, but if you get that pump tool that goes down the distributor shaft, you can prime the pump. You have to remove the distributoer for that . I know! Is there ay way you could hook up a compressor to where the oil pressure sending unit is and pressurize the engine with oil ?? I don't know if that would work. I wouldn't use much pressure, maybe 15 lbs. Or would placing a tube over the dip stick hole and presurrizing the engine that way?? I'm just trying to think of a way to move the oil to get that pump primed good.
