The aluminum bolts on the timing cover are broken causing an oil leak. If the all bolts are made of aluminum then what about the transfer case? I've heard about near accidents because of bolts breaking either because of the material difference between the bolts and the magnesium in the motor. It has occurred on other models of Porsches. Porsche should recall and fix the aluminum bolts on all parts.
