All the prev post are very sound advise....

If you check all the prev mentioned and the leakage is not solved... you will need to have a closer look at the coolant tank itself....

Mine was originally leaking at the O rings... but as I made the mistake (or fortune ?) of re-installing the valve a second time and probably used too much force the 2nd time around and ended up leaking at the coolant tank itself....

The leakage from the coolant tank can be very difficult to find... Mine was leaking below the breather valve and on close inspection, it looks like 3 little scratches on the plastic of top of the coolant tank... But leak it did (very very slowly and u can hear hissing everytime the temp reaches 85 degrees or so).

So... if you hear the hissing noise, don't assume it's the breather valve working... (I did and was wondering why it vented so early, until I saw drips of coolant bubbling from the bottom of the valve housing).
