Default coolant hard pipe

i am having a leak right around where the coolant hard pipe goes into the back of the water pump...
i have replaced it with a new gasket still leaked, tried silicone alone still leaked, tried the gasket and a little bit of silicone and still leaked?? now i am not 100% sure but it seemed like it leaking from the gasket area.. Does the pipe itself leak alot ?? i have tried taking the pipe out but couldnt find a way is there any way without removing the manifolds? thanks any advice will be great

You can try replacing it

Its possible that theres a hairline crack in either the pipe or the head (or where ever its leaking at). A friend had this very similar problem, I changed his water pump and it still was leaking... Found a crack on the head.
