I have a question about camshaft timing. Yesterday i was timing my ADU camshaft/engine. And i realized that my 7a/head in the Urs4 is not installed the same as the ADU head i have for my RS2. The RS2 is all original though, the Urs4 have Tommisbillet cam sprocket. I'm thinking i might be wrong on the Urs4/7A head because of me not knowing how the cams should be alligned. The RS2 with org camshaft sprocket should show me the right set off of the camshafts, while the Tommis is adjustebel, and i may have timed the camshafts a little wrong. The Audi Manual is'nt that specific about the timing i think. So i'm asking you, what is the right setting f the cams according to the pictures?
