Hi I have a leak somewhere on my 318, but have struggled to locate it. The oil and coolant warining lights have been intermitant. there is a little oil / water mix in the dip stick, but it is a very small amount so im hoping there is no lasting damage to the head, even if it does need a new valve gasket. It hasn't over heated I lost a load of water coolant after complelty filling it up within about 20 miles and it seems to be dripping from underneath. It can't all be mixing with the oil otherwise id imagine there would be more than what is shown in the photograph on the dip stick I have attached 2 photos, one of the contamination on the dip stick and one from the area that seems to be wet enough for the leak to be in the facinity. Could someone advise if they think I need to replace the valve gasket and whether or not the 2nd photo shows anything that might be common causes of water leaks ? Thanks Brett
