So did a bit more research regarding what i though was crank walk issue. None of the bearings including the thrust bearing show signs of damage and the crank has no visible marks on it to suggest it has scored the block, so i dont think it is damage. I looked at a few pics of split ej25's and they also have the same markings which suggests it is a factory finish as shown below. Afew of you probably already knew this, but being my first engine build i am going to be extremely thorough.
next on the list is bearing clearances. I have a number in mind after doing some research, but will be chasing this up with real life people.
