Good morning, i need to remove my pump, it has developed a chronic leak, i believe it to be round the back as i changed the main and crank seal before it was fitted, what's the little one round the back at the bottom for, anyone know?
anyway, correct me if i'm wrong please, remove cambelt cover, turn crank until pump pulley lines up with holes, screw two intercooler bolts all the way in to lock the pulley, then remove all lines, pulley nut etc and pump can come away for re-sealing? . . .
i've removed a bosch from a scrap car before but not fitted one or taken necessary precautions to refit . . .
any thoughts? cheers, Matt

yeah essentially what youve said man nice nad easy to do. i always mark mine when i take them off a bracket as well so i know where to put them back as it was obviously running right. the seal round the back is on the advance mechanism. You can do it without stripping the entire pump. In my opinion though its worth re sealing the whole pump while its off.

Thanks mate, what else is there to seal? lol I did the crank, main body and throttle shaft seal before I fitted the pump
Edit..... I know there's plenty more to seal looking at the seal kit I still have lol, not sure I want to blast it to pieces tho, need the car Mon to Fri

it could do with a complete re-seal no doubt, it's kind of amusing, replace a seal and another starts leaking, path of least resistance and all that
