Well they said they have seen strange issues with after market cam sensors in the past so we will see, I also think its unlikely ( I already changed this but for another after market) but we will see, If it works I will be happy, but I think its unlikely it will solve it. I've got a feeling its going to be something annoying like the crank pickup ring being in the wrong position or which I really don't want to find out that someone at some point has done something weird with the cams, maybe uprated, who knows if this would have an impact? maybe the oil channels are blocked in the head.. can't think of any other possibilities.
