After fitting another new oil pump (initially fitted the wrong one!) and a new distributor (after the oil pump wouldn't spin and sheared the dizzy shaft!) I still have poor oil pressure, as the engine sounds like a bag of nails, and the oil warning light flashes continuously.

I now realise that in my haste to fit the oil pump I didn't prime it. I dunked it in oil and span the shaft a few times but didnt fill it with oil. However due to the buggered dizzy it was never started just turned over a few times when I thought my luck may be in.

I fitted the new dizzy today and it started first time but I turned it off as soon as the oil light didn't go off. I have since done the research I should have done before and poured oil down the oil filter housing where the 1.8 bar pressure sensor is.

But the oil light still flashes. My concern now is that I've fubard another pump.

I'm clutching at straws but could it be an air lock in the pump, or how much oil should the pump hold? I put about 200ml of engine oil down the sensor hole. I read about packing it with vaseline so that the oil doesnt run out....could it just be that it took so long to dribble the oil down the hole, it had ran out the pick up by the time I went to start it?!

Please dont say i have to take the sump off again!!  :cry:

Sounds like no pressure so I think the pump is in trouble :smiley:

Have you tried spinning it over woth the coil lead off and seeing if it will build pressure that way.

I replied to this on the other guys thread!  :tongue:

No I haven't but would that not be the same as me trying to start it with a broken dizzy (the hall sender was out)

Yes, guess so, if it is not building pressure then you have oil pump issues.

if you can find a way of running the pump shaft with a drill that can sometimes sort you out. leave one of the oil pressure switches on the filter housing off while you spin it up, when you see oil coming up out the hole you know you have oil pressure :)

Been out this morning and took the coil lead off, and both oil pressure senders out. There was a little dribble that came out the one on the head so put that back in really loose.

Turned the car over about 5 times, about 3/4 seconds each time and had no oil come out the hole by the oil filter. I dipped a little vac hose down there and it came out with no sign of oil on it.

Therefore I'm guessing my pump is out. Thing is it is a brand new unit!! Once out is there anyway I can check it? I was going to try the drill trick see if it picks up oil.

Is it possible that a release valve is blocked......these are built into the unit are they not?

And my major worry.....if it isnt the oil pump then am I looking at a duff bottom end?!  :sad:
