The leak is from the pipe behind the exhast manifold, what is the name of this pipe and how do i fix it?:confused:
 
One common source of a water pump leak is the o-ring not installed properly. You must replace the o-ring in the crossover inlet pipe by putting it on the pipe end first, coating with coolant, and then insert pipe with o-ring into water pump – do not put the o-ring into water pump first as it will not seat properly and will leak.
Also do not use RTV on the water pipe. The o-ring does the job of sealing the water pipe to the pump housing and doesn't need anything else. The RTV will reduce it's ability to seal and flex and can actually create ways for the coolant to leak. Make sure that the water pipe is free of any corrosion where the o-ring sits and that the o-ring is lubed with coolant before putting the pump on so it isn't cut or torn. Take a scotch brite pad (the green kitchen scrubbers) and polish the water pipe end if necessary. Use a new o-ring. Make sure you don't scratch the inside of the water pump.
 
I have seen any rubber hoses near manifold or turbo to get really weak and stretch and wear around where it clamps. I have also seen this on the smaller Oil Filter/Cooler water hoses(small few inches) to turbo inlet for water cooling too.
