ve been an idiot today. Dont ask me why but i did rotate the inlet camshaft with the timingchain off and the exhaust camshaft in Place. I have my 3.8 engine out of the car so i did rotate by hand with the help off a plier. I felt a Little recistance in one position. I rotated a couple of turns until i relized that it was the valves that hit each other. I must have left my brain elsewhere. Have i bent the valves or im lucky. It is free to call me an idiot.
