HELP!! Coolant Leak

My 156 JTS is leaking coolant. Its dripping from the underneath the A/C compressor and also from the oil filter, but i cant find the source of the leak. Is it possibly from the water pump or the plastic coolant jacket that runs along the front of the head. There are some picture. It would be appreciated if anyone could give some advice as were to look or if there is a common problem.

That plastic coolant manifold on the JTS has been known to crack.
Pin holes in the pipes to the oil cooler (oil/coolant heat exchanger).

I recently had the same problem. It was the plastic pipe along the front of the head. The gaskets deteriorate and leak. Mine has been fixed temporarily by tightening up the bolts that attach manifold to head. Long term I intend to take the manifold off and fit new gaskets but its a pig of a job so just monitoring for now. Your leak looks much more severe than mine thus maybe your tube is cracked?
