Can anyone let me know what is this pipe? and where can I find a replacement or DIY?

A little more context might be helpful like year and model as well as a better picture that shows the location of the leak on the engine. It is likely a coolant leak as Porsche coolant is pink. Has the coolant been changed recently? If not it might be time to change it. I've found that sometimes the aluminum fittings will start to corrode where the hose fits over them leading to a small leak. Sometimes it can be resolved by repositioning the hose clamp or easing the tension on the hose clamp and twisting the hose to reposition it a bit on the fitting.

 

That is a SEEP, not a leak. And it is from your water pump. It just suggests that your water pump may be a problem some day soon.

 

Waterpump is far from this pipe. It is not leaking but there is some coolant deposits. I highly doubt waterpump has anything to do with it.

i think since car has 100k+ miles, the silicone hose is wearing off and needs replacement soon. I just dont know what part number it is
