After a few isolated occurrences of problems with defect cylinder head
gaskets on BMW Z8 vehicles with high mileage, there seems to be a
problem in general with dirt and debris in the radiators of all BMW Z8
and ALPINA Roadster V8 vehicles.
The temperature display on
the instrument panel works quite sluggish, once the indicator lamp
lights up, it’s often already to late! Damage to the head gasket is the
consequence. Unfortunately an oil-temperature display is not build into
the Z8.
