ticking e36 328 - terminal?!
Discussion
the plastic impeller on the water pump disintegrated on track recently and the car overheated. i was hoping the head or head gasket hadnt cooked
ive replaced the pump and viscous fan unit today and the system has bled ok. all seemed ok..... i though i'd got away with it..... and then the ticking started, quietly at first then increasingly noisy... its not quite banging and doesnt seem like its bottom end, its definately top end. so whats the options? its still firing on all cylinders so hasnt dropped a valve. could it be a sticky tappet? its not worth much so anything too expensive is going to consign it to the scrap yard!

Before you do anything else check that your spark plugs are tightened to the correct torque. I started getting a ticking noise from the top of my 323i engine and my mechanic discovered a loose spark plug - the noise was the compressed gasses forcing their way past the spark plug - sounds just like a ticking tappet. Worth a try.
