Im posting this on behalf of a friend.

i have a vf5, and its leaking coolant from the headcover.

i have taken the headcover off and noticed its leaking from below the tool release piston and above the spindle, so its obviously the through spindle coolant.

we have not changed any parameters, have tried a new tsc service kit, check valve and also checked that there are no blockages in the hoses.

any help would be much appreciated.
