What was supposed to be a "simple" head rebuild turned into a complete engine overhaul and rebuild - block rebored, stroked, polished head, new pistons, rings, etc. This is on my 1999 GR (GU) RD28Ti. Now with the complete rebuild, is there a recommended break-in period for the new motor? Are there certain things I should and should not do during the break-in time? This will be my first time breaking in a new diesel as all of my other vehicles have been petrol, so any advice would be greatly appreciated.
