So after further investigation it seems the headgasket is on its way out again, great
I am not going to put any more money into this money pit of a car so the situation is this, I will be running it daily and keep topping the coolant up until poor beemy dies.
I will then be either selling as spares/repair or breaking.
Reasoning is that I have spent far to much money on this car to the point where I dont enjoy it anymore and promised myself last time the head went that it was the last time i was spending big cash on it. If I can find a suitable car in the meantime and trade it in then I will take that opportunity and keep my eye open for a 6 cylinder e36 to replace it
