Thanks Nicam, Yes that's the situation, I might have to take the rocker cover off and see what it is, It's solid because I tried to move it thinking it may have been an oil feed but no movement at all. The compression info is invaluable thanks, i'll try to investigate tomorrow and report back!!

Hi!! All seems well as the obstruction was the rocker nearest to the injector being at it's highest point so I brought it down to it's lowest and hopefully that will be fine. The final 2 injectors havn't arrived yet but should be here soon so we'll see!!
