I have a 2003 Toyota Highlander 2. 4l that had engine failure due to 3 headbolts on the intake side of the head become loose as other numerous folks have experienced. The engine blew the headgasket and lost compression/power and died. The seems to be a very well known issue by Toyota, repair shops, and salvage yards. Seems someone should hold Toyota reponsible for repair cost - I. E new engine since this is an obvious manufacturing/engineering design flaw. Beware of Highlanders, camrys and ravs since they all have this 2. 4l engine.
