Getting myself all confused here! I am just trying to round up all the little last minute bits and bobs that need to go on this engine before attempting to fit it.
About 25mm below the knock sensor is an M8 threaded hole in the block casting, its not rusty and has a ghost mark like something was screwed into it.
I dont remember taking anything off there, but senile dementure may have taken over as I have been trying to do so many things in the past few weeks that I may just have done.
Anything go in there?
