firstly how do you tell the difference between the top and middle ring on a zetec??
secondly if i have brand new 84.5mm oversize pistons and rings then how big does the bore have to be??
if i slide the rings down the bores there is between 1mm and 1.25mm gaps so is this exceptable on a newly bored lump??
my engines a smoker but i cant see anything at all wrong woth it other than it being just all new parts.
i think my ring are not it the right slots though.
please help
