good to see your still with us Penngwyne,hows that old mitsi of yours?
Hi guys, some advise please...
The wife's 1998 E39 M52 520i has lost it's coolant.
The wife was idling waiting for a friend and the coolant disappeared
I've checked all the hoses and there's no leak
I've refilled the coolant and it's not leaking nor is any escaping
I've checked the oil and it's light brown and very watery thin
I suspect the coolant has leaked into the engine oil via the head gasket
Does this sound about right?
Also I take it that's it not a good idea to drive while there's coolant in the engine oil as this will increase the temperature of the engine and is likely to cause cracks and increase costs further, as an interim stop gap could I replace the oil with some new oil without coolant and see if this holds the oil and not coolant? Could it be driven like this and check the coolant daily? The wife only uses the car for frequent short daily trips.
Obviously this is a drastic and expensive repair assuming it is the head gasket and am looking for any further advise for things to check before we part with the time & cash on getting this repaired. (or it could be cheaper to chop the car in px for a similar car than paying for a new head gasket?) many thoughts and your advise would be greatly appreciated thanks guys!
