Measuring Cylinder Bore Taper
WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
Measure the cylinder bore along the thrust surfaces, perpendicular to the crankshaft centerline, at 10 mm (0.394 in) below the deck surface (1) and record your measurement.
- Measure the cylinder bore along the thrust surfaces, perpendicular to the crankshaft centerline, at 125 mm (4.921 in) below the deck surface (2) and record your measurement.
- Calculate the difference between the 2 measurements. The result will be the cylinder taper.
- Compare your results with the Engine Mechanical Specifications . If the cylinders exceed the specifications, replace the engine block.
