Let me explain the issue...
ALL bosch VE injection pumps have a vane style low pressure pump in the front nose, for lifting fuel into the pump body, and holding the correct regulated pressure inside the VE housing to work the advance system...this pump is a hardended steel pump, in a steel ring housing, the back side of the rotor / vanes however, run against the ally ve case housing...what has happened, which is fairly common, is the vane pump is worn / totally shot (teflon coating gone, scored steel on steel) which I can normally get around by replacing just the pump, but this is so far gone, A totally new one was really the only option as it has scored the hell out of the casing itself (only ally).....this again normally isnt an issue, as casings are everywhere, but these BMW pumps run a strange nose / bolt hole design, which are acaully pretty damn rare / expensive, and as ive just found out, can no longer be purchased new...
That is the issue...I could put a second pump back in, and it might work for a bit, but meh, its a lash, and Chris said hes got overheating / rust issues, so isnt that keen anyway I dont think...
