Hi all, just updated from a 2008 D22 to a 2015 D22, why well the 2008 had a minor exhaust manifold gasket leak and heated the head gasket and melted the plastic of the head gasket right near the port were the oil runs back to the lower end of the motor has anyone ever had this happen??? I must say so far the newer D22 seems a little better on fuel and has a softer ride so possibly a cheaper suspension not sure though, even though I had an issues with the last one I'm still happy with the Navara and the price I got it for. cheers all.
