97 2.5 possible head gasket prob? rad pressurising - carnut1980
my 97 523i touring, (manual, 145k) has developed a problem. It was driving fine but now it overheats and theres a slight tapping noise on idle. I had put a new final stage resistor in, and that has also blown. No way of telling if the air is getting warm inside, so im not sure if it is a w/ or h/g problem. I fear the latter, although it had a recon head fitted 6 months ago by previous owner. The rad boils ove and leaks past rad cap, i tried bleeding it but no water shot through the small hole (isn't it meant to?)
