Finally gave up on the engine and have bought a 40,000 mile replacement which arrived today. Changing over all the missing bits I decided to swop the rocker covers and couldn't believe my eyes...the swines have taken the injectors out and stuck the cover back on. So I need to swop out my original injectors to the new engine...I got the bolts and spacers out and I can turn them a little left and right...but how on earth am i supposed to pull them out? I can't see anything else holding them in place so I guess it is just the O rings being tight. Should I wrap some wire round the springs and tie them to the engine hoist and try pulling them out of the engine? I can't get a lever in there and I can't think of any suitable tool...even if I has a slide hammer I have no way to attach it. Any suggestions.... anything considered.
