It's not a common repair, but I have seen the passenger side head gaskets
leak on these engines. There is no bulletin or recall for this. You will
footing the bill. Make sure that you check carefully for the origin of the
leak. The water pump gaskets on these engines also leak, and the position
of the water pump gasket can make it appear as though its leaking from
the cylinder head gasket area.
