please help me !!

If your asking a question like that I would recomend taking the vehicle to the shop. The entire top end of the engine must come apart and if you don't know what your doing you could hurt yourself or destroy your car.

That is an incredibly detailed process. Your best bet is to go to the auto parts store and buy a repair manual for your vehicle. That will detail it for you. They will also have all the torque specs and tightening orders that you will need.
