Help! I was trying to locate a valve train tap which I thought might be a stuck tappet. I had the rockershaft off and gently pulled up on the number 2 pushrod, when oops! it seems I pulled the tappet out of place. It fell out of the way of its home as I can see the cam lobe through the pushrod hole. How do I go about fixing this foul-up? Please tell me that all I will need to do is drop the oil pan, find the tappet and replace!?
