has my oil pump failed?

[Benn]

0 pressure and running it means damage. Simple as, unless you are some how very very very luck.

I wouldn't run a car with 0 pressure.

You need to get the oil pump off and try another, Id remove a crack cap too and look for scoring on the crank/bearing. If they haven't had oil on them they could be buggered.

Iirc the pump is 8 bolts. Then a philps to get the pump its self apart.

you can do it, youve got the skills marc

like phil said, yours might possibly look like a bit like this on the inside :

Thanks for the encouragement, am I right is saying it is similar as Haynes guide for the ohc 1.2/1.3??

Removal of cambelt, and pulleys and back plate etc to get to the pump? Bearing in mind it took me 5 hours to change the cambelt earlier this year....I am not joking.

If I am capable to do the pump, is there an easy way to see if I have damaged the engione/scored anything whilst I am there?

Whip big end bearings off rods. Generally you will see bearings picked up/spun/damaged. Otherwise without measuring crank theres no other way too tell. (Thats if bearings look ok)

^ yeah, pretty much the same marc, with a few extra bits in the way of the back plate.

the haynes says for c20xe :
---------------------------
- remove all the pulleys/sprockets/rollers/tensioner to gain access to the back plate.
- remove the sump, the oil pickup pipe, and the baffle plate.
- unbolt the oil pump
- clean up all the mating faces. smear the new oil pump gasket with grease and place it on the pump.
- grease the lips of the oil seal and refit the pump, being careful not to damage the oil seal as it passes over the crank.

if you spin the engine over so the timing marks are lined up before you pull it apart, will make things easier

hope that helps

if you have already taken the sump off you are only 2 bolts away from changing each bottom end bearing (big ends likely to be more wasted than mains). But its too early to jump to conclusions.

Thanks for that,I'll probably be a few weeks building up the courage to even start it..unless anyone is near Aberdeen and wants to help!

Have you tried the sender? My 1.3 was showing 0 pressure at idle but there was loads of oil in the cam box. Swapped over the switch and now shows the correct good pressure.

Unfortunately there is no question about the oil pressure, there is no oil getting pumped in the engine at all, I wish it was just a bad pressure sender.
