love ke70 Posted December 17, 2006 Report Share Posted December 17, 2006 hey guys, just rebuilt a 1995 323 astina. i know, thats where i went wrong, but its my sisters car, so i gotta do the right thing. anyways, all went well except the oil filter seal not sealing so i pissed a sump full of oil onto the shed floor. another new oil filter and some oil and all went well. drove it to work in the typical running in, aka thrash it, style of driving and all was well. got back in that afternoon and oil light stays on.... so i tow it home, and think maybe dodgy sensor, remove sensor, fit new one. nothing. remove sensor, start motor (yes, nothing in the hole...no oil comes out. nothing. not even a token drop!!!) so, sump comes off, check, pick up still in place. next, oil pump comes out...well its still there remove oil pressure relief valve, split pin, washer and spring comes out. but piston isnt having a bar of it. doesnt want to move. is this normal? could this be cause for no oil pressure? what else may it be? I'm at a dead end. cheers, andrew Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted December 17, 2006 Report Share Posted December 17, 2006 Hi, If the piston in the oil pump is jamed in it is the pressure relief valve so I would imagine you would havve to MUCH pressure. But wwhat could of happened is the piston jammed and then over pressured the motor and pushed all the oil out or it got burnt. So while driving was there much smoke? Also the small piston with oil on it some can be hard ot remove so have you tried so wire and pushing it from the other side where oil touches it? as the oil can stick it in a bit sometimes?

love ke70 Posted December 17, 2006 Author Report Share Posted December 17, 2006 i drained 3 litres of oil from the sump. try again. wire wouldnt help its in so tight Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted December 17, 2006 Report Share Posted December 17, 2006 MMM well inital idea out the windown. Did you pull the oil pump apart? As the main rotor that spins to pump oil could be slipping on the shaft as I have seen some wiht a pin in it or a press fit so maybe it is slipping?

love ke70 Posted December 17, 2006 Author Report Share Posted December 17, 2006 flats on the crank and in the pump. no slippage. and even with slippage itd still spit a token drop I'm sure Quote Link to comment Share on other sites More sharing options...
Jason Posted December 17, 2006 Report Share Posted December 17, 2006 pick up to close to sump? (if its those flat type ones) Quote Link to comment Share on other sites More sharing options...
love ke70 Posted December 17, 2006 Author Report Share Posted December 17, 2006 what do you mean by flat type? its all stock unmolested stuff, so I'm figuring thats not gonna be the issue. Quote Link to comment Share on other sites More sharing options...
camerondownunder88 Posted December 17, 2006 Report Share Posted December 17, 2006 Is all the oil pump housing tight like it not pumping but cover of pump lose so oil coming out there? Or internaly is it all meeting up eg oil holes so it can flow? Also when you ran the motor with no oil pressure did it make any noises or a bearing hitting from low oil pressure etc?

love ke70 Posted December 17, 2006 Author Report Share Posted December 17, 2006 oil pump was all good. all holes are meeting up when ran with no oil pressure she got a bit tappety, hydraulic buckets you see. Quote Link to comment Share on other sites More sharing options...
