I started out to do my water pump thought it was leaking so started to do it from this site.When i jacked up motor i noticed it was leaking(or thought it was leaking)from upper oil pan gasket.Well i decided to abandon water pump c/o but the screwdriver i had holding again slipped out before i turned motor back. So i did the upper gasket etc. If i do opposite with the tensioner and screwdriver do you think i could line the timing back up i already started car sounds horrible.
