Normal
seems to be common problem as the 39 ages... in my case its was a hairline crack, cylinder head..same problem, only discovered when open engine, which was the last choice of coz...this is after changin the whole freakin cooling system$$$water pump,hoses,radiator,expansion tank,fans,belts etc etc and yet the problem persist.. it was quite a pain looking for the double vanos(528i) cyl head.. just the head cost 2800 for a used refurbished set.. did a top overhaul too since the engine is ald open.. in total spent about 12K, plus some wear and tear stuff.. the crack is so tiny, i could hardly see wt my naked eyes! but thats where the small quantity of water went missing slowly... now its a dream to drive this machine!!
