I have a 2002 PT 2.4 with 60,000 miles. Over the last few weeks, I noticed on two ocassions, tennis ball sized wet/damp spots on my driveway under my PT. I'm assuming its antifreeze since my overflow was a tad bit low and the spots dry up after a day or so. I am 99.9% sure its antifreeze. Definitely not condensation or water by any means, nor is it ps fluid etc.

I've had this PT on my lift running for an hour checking everywhere underneath. I looked all over from the top - hoses, radiator, etc. Nothing.

I've taken off the splash shield and tire to see up there for leaks. I've used mirrors and bright lights, but can't find a drip. I've even looked at where the head meets the block for head gasket leaks - nothing.

I don't have a pressure tester, but I've had it running for over an hour at idle to the point where the fans are on. Its fully hot and pressurized.

Any wierd possibilities? Techs?
