I am guessing you mean camshaft bent. The load goes in that direction, due to valve spring pressure, that is why the pattern. Do you ride in temperature under -5deg C? if not I suggest you use an oil with 50 wt as the hot end of the scale. Unless I miss my guess that journal is the last place in the engine to get oil, so it will have the lowest pressure. Sooo, when idling in traffic on a warm day with thin oil, there will be very low pressure at this point in the engine, hence the marks. Speed the idle up to 950 from the stock idle will add about 25% oil pressure in that situation. This is well documented on this site and I am sure others, it is a rocket specific problem right from the get go. Yours is an 06 model, CHECK the size of the oil feed insert in the head. Hope this is useful.
