yah the pin on my timeing spocket sheared off as well and the hole looks like it is mal-formed so I just ordered a new timing sprocket. You might want to check the locating pins on the back of the sprocket that hold the crank position blade and spacer. I'm thinking I might replace the crank position sensor too in case it was damaged by the blade or spcacer when they sheared off.
