The play values measured between the valve cup and cam must be the following:
For all intake valves 0.15 ÷ 0.24 mm
For all exhaust valves 0.20 ÷ 0.29 mm
If different values are encountered even for one valve, substitute the camshaft/valve cup play adjustment pads as
described in the F4 1000 workshop engine manual F4 1000 (Code 8000B4302).
If the values are correct, reassemble in reverse order to disassembly. Consult the F4 1000 workshop engine man-
ual (Code 8000B4302) for the specific torque pressures and the necessary products.
