Hi, I had to get a new cylinder head. Got a C20XE engine without a distributor (I think). Then I bought a used Cossi head from a 16V turbo. I had in my engine tuning camshafts, but unfortunately I can’t find the description of the waves anymore. When I built the shaft on the new head from the turbo, much of the waves can’t be turned on me. Where the individual cams are, there are too big edges in front of the hydropumps. I had to d The previous owner of my engine, who also installed the camshafts, used two identical camshaft wheels (same part number). Therefore, there is something wrong with the markings. Once you can put the wheels in 5 different ways on the shafts (where the wheel is screwed 5 holes which are also labeled) and which is also very funny that the wheels are once a notch On one gear, the marking 8 teeth is removed from the notch. Can’t explain what these yellow markings should be for. So 1st question: Can it be that I need another camshaft with a little less stroke? Then I should not have milled away. Does the turbo have other waves? 2. question: Does the turbo have a different hydropump than the XE? 3. Question: Someone’s idea of what the yellow markings should do?` I thank you in advance
