I don't see any tracks or signs that there were leaks. The overflow bottle is fine - I replaced one years back on a Neon that had a tiny crack in it, so that was the first thing I was looking for - thanks though .

Like I said, I spent at least an hour under and above it with lights and mirrors with the car running. The car was fully hot and not a drip.

About once a year I notice that the overflow bottle was a inch or so low - maybe a pint if that, so I do refill it - about once a year or longer.

All I am going to do is keep looking for any wet spots under the PT.

I don't know about putting that Bar's Leak stuff in. I fear it clogging something up over the long term. People swear by it though...
