Hi,

When you see the leak, the best thing to do is this: Get a pressure tester (most parts stores will lend you one) and slowly pressurize the system when it's cold. Once a specific pressure is reached, the leak will start. At that point, see if you can identify the source.

By doing it this way, you can take your time and not get burnt. Here is a link explaining how it's done:

Also, if possible, take a few pics of where the leak is seen. Hopefully, I will have a few ideas as to where it could be coming from.

Let me know.

Take care,

Joe
