83 944 has leak.. Need help...

I am a new Porsche owner recently purchasing a 1983 944. However I live in an area where Porsche specialists are impossible to find. I have a leak in my Porsche and I was curious if anyone could tell me what it could be. I believe it is a gasket leak that needs to be replace, but I am having trouble getting a parts estimate to see how much parts alone would be to determine if it was worth putting the money into.

The symptoms are as follows.

1. Can start and run in park, and in fact runs well. The leak starts a little after it has been running.
2. The leak is obviously coolant.
3. When the car is shut off the leak continues for a short period, then slows to a drip.

There is a picture with the area that is leaking high-lighted. the surge of the leak comes from two bolts.

Thanks in advance.
