i have a 1997 gs-t and i carelessly drove it with no oil . it started making a ticking, clicking sound and eventually grew louder and was not drivable. from reading around i understand that i probably have bent valves, damaged pistons, and off timing. so the question is: will i be able to fix the car just by replacing the whole head? are there any other components damaged? and what will it take to fix this problem?
