I don't know the full history of my engine, it has about 120 000kms on it. It had a genuine head gasket, bearings and timming belt in it So it doesn't look like the engine has been pulled apart.
I realise the difference between the pistons, my pistons have the thinker top ringland. (should of said N1 type pistons)
Also is "n" with a single dot above it are the markings for N1?Because my oil pump also has this marking.
I could be wrong.... would be keen to hear from someone who has actually pulled a Neo apart.
I'll be able to throw up a few pictures on here in a week.....
