Anyone help with AAN/ABY/ADU valvetrain specs?
right im new to Audi engines so looking for help after years of being specialist in Cosworth stuff!
after my A4 belt tensioner gave up i stripped it to fit new valves and found double valve springs, is this a standard AAN setup?
how do i identify the 5 cyl ~Audi cams, markings? or whats the duration specs on different cams when measured with a vernier or DTi? lift/ duration etc.
my engine was supposedly modified but to what extent nobody knows, was remapped etc and it made me curious with the double springs!
Cheers, Sean
