had a wierd thing happen a couple of times now.

Stopped somewhere and came back to find a pool of coolant underneath. usual paranoia, check everywhere for leaks, find none.

Check water and ive lost a good half litre.

So top it up run it until fans are on, add a few revs etc expecting to see water dripping out somewhere.

None comes out.

So make my way home and paranoidly check water daily to find no loss!

Now 2 weeks later its done the same, gobbed out 1/2 litre with no sign of leaks.

It appears to be front of engine near the thermostat area.

Pipes all checked.

ive had it running with thermostat open yet its not leaking open or shut!

So any idea whats going on to make it randomly leak large quantities of water then stop?

Bit confused
