I have an 01 STS that has a mild intake leak at the rubber coupler between the intake manifold and water crossover assembly. I have tightened the 3 t-body bolts and the large clamp at the intake bit more but the leak is still there. I know the coupler needs to be replaced but does anyone know if I have to pull the intake off, or can I just remove the t-body bolts and clamp and squeeze it in there?
