What kind of shape is your cap in? O ring? Cross threaded? Rev -04? The bleeder valve has two o rings that can be replaced. IIRC there have been instances of mini cracks that leak only at operating temps.

It looks OK but ordered a new cap just in case. Is there a problem adding more distilled water until I figure out what I'm dealing with? I'd like to get it to a safe level and let it get to operating temperature.
Then I have to figure out what coolant I need.

In addition to the new cap... check the two O-rings on the bleeder valve.

Good luck!

How old is the coolant tank ? They are known to develop cracks and leak .

I don't know how old it is. It looks pretty good so I doubt it's the original one. Ran until temp got up to 180, nothing, no leaks. I know it's too early to tell but I'm wondering if the cap wasn't tight or cross threaded. I'm gonna take it for a limited ride tomorrow and see what happens.
Any recommendations on anti freeze?

Been there, done that. Cross threaded and lost a bunch of coolant. Readjusted the cap and never had a problem again. As for the coolant itself, get the real thing from Porsche. Expensive but how often do you buy it?
