Hi folks, I've had a coolant leak for a few months now. It's emerging from drivers side, dripping down over starter motor
onto the ground but I'm having trouble finding the source. It seems to leak about 1litre per 300 miles but if I'm parked
facing down the drive (very very steep) it can leak the same amount out overnight.
I've had the egr, boost pipes etc all off to try to find the source but very difficult to see.
i first suspected the coolant hoses at rear of engine but the furthest up the block I can
see is the base of the head at the gasket. Is it a likely place for hg to leak?, seems odd.
Other possibilities could be a core plug or indeed those hoses at rear of engine but I can't see
a plausible route for it from these to the base of the head, then down towards starter.
any thoughts would be appreciated, I took a pic with a mirror under the bottom of the head,
may be of help-
