your not the first and wont be the last. im not to up on the puma engine bust most others you will see the pin if you drop the sump. i take it youve tried to get the pin out but it wont? all i can suggest is take the sump off,either try and straighten the pin with some grips or snap it off. then the bolt part should come out.obviously you will need another pin to to time the engine. hope this helps
