DennisB DenLorsTools.com © Summary: Toyota’s with the 2.4 four cylinder engine have a common issue of blown head gaskets because of the aluminum threads in the block failing for the head bolts. The middle three or four in the back of the head are usually the weak point, which can become stripped. However, we recommend repairing all ten holes to prevent having a repeat head gasket failure due to stripped threads or pulled threads. This also prevents the possibility of the threads failing during the torque process right after putting the new gasket and head back on the block. This can be very frustrating and has happened to our customer’s more than once! Vehicle’s affected are the Toyota Camry, Rav4, Scion, Highlander with the M11x1.5mm head bolts.
