That is a break down of the cooling system for a turbo model.
I assume you replaced the water by-pass pipe gasket, part 16278A in the diagram.

YEA I JUST CHANGE THAT GASKET AND I STILL HAVE A LEAK THATS COMING FROM AROUND THAT AREA I DON'T KNOW WHAT ELSE IT COULD BE ANY SUGGESTIONS
Did you remove all of the old gasket material? It usually takes a half a day and alot of elbow grease. Personally, I wouldn't have used the permatex. Just get those surfaces as clean as a dinner plate. And last but not least, did you properly torque the nuts? They don't list a torque spec, but if I remember correctly they are 12mm nuts, so I would torque no more than 13ft/lbs. I would also be looking at the water outlet housing and where it meets the cylinder head.
