    Timing problem with 2.5 stroker engine

    Hello guys! So i need some photos please if some one can take itToday Im commenced to fit timing belt on my stroker engine 2.5 with diesel block,BUT i met the following problem:
    Crankshaft pulley is align on the mark, belt is the standard AAN 151 tooth with custom tension bracket and standard AAN pulley belt. Both camshaft are correct align and as all know its appear some miss align on camshaft sprocket, which is original AAN unit. I need some photo please on standard AAN engine where is the shutter window for G40 sensor when is align on the marks .As you can see the miss align as per the attached photos:

    Factory mark on the crank pulley is pretty much useless - you should measure TDC and make a new accurate mark. You will find actual TDC probably around 10deg away from position in your picture, but most pulleys are different! Don’t forget smaller RS2 water pump pulley will affect cam pulley marks due to belt chord length between crank & cam sprocket.
    I make an extra mark to be able to set base timing & trigger offset. Measure properly is the only way to be sure
