1* Measured with the camshaft bed removed.
2* Determined by the Plastigage kit with the rocker arms removed.
3* Not counting the quickly wearing graphite coating with a thickness of 0.02 mm.
4* Determined by a Plastigage kit when tightening the crankshaft bed fasteners/connecting rod bearing caps to 30 Nm. Main bearing shells worn down to the nickel layer must be replaced before measurement.
