replacing the intake manifold gasket consists of a few steps ::: Step 1. take loose the intake tube from the intake and breather box. step 2 remove the wiring harness from the intake mahifold there should be 4 injector plugs 3 plgs on the back of the manifold step 3 you must take loose the fuel lines both the supply line on the left side of the fuel rail and the return line on the fuel pressure regulator step 4 throtle cable must be taken off of the throtle body(and also dentent or shift cable if it is an automatic trans.) step 5 there is going to be a bracket on the underside of the manifold that more than likely will have to be gotten from the bottom should be a 14mm take loose from the manifold not the block step 6 there will be 8 to 10 12mm bolts that hold the intake manifold onto the head all of which are hard to get with the head still on the car but it can be done for a couple of them u will need a wrench and possibly even a swivel socket step 7 remove the intake and pay attention to the hose that runs from the intake to the oil breather on the back of the motor its a bit tricky to get back on if u dnt have samll hands step 8 make sure the gasket area of the intake and head are clean before installing the new gasket step 9 reverse the instructions to replace the intake and make sure you torque the intake stud nuts to 16 ft/lbs
