    Could someone share a picture of the timing marks for valve timing/camshaft?

    I assume they should be the same as on the 400/412.

    Thank you

    The camshafts are just the same except that the inlet camshafts are offset by 2° (so that's an additional valve overlap of 4° at the crankshaft). At the end of the day, the only difference between these camshafts are the timing marks that are 2° apart.

    Bad picture of my 400i, but you get the idea...

    Great, thank you very much.

    What has to be removed to inspect this with the engine in the car?
