Compression Check

NOTE: Measure compression with the engine hot and at wide open throttle

- Normal value B5234T and B5254T: 1.1-1.3 MPa (156-185 psi)
- Maximum deviation between cylinders: 0.2 MPa (28.4 psi)

NOTE: This applies when the engine is warm and the throttle fully open and the engine being turned by the starter motor at 4.2-5.0 rps (250-300 rpm).
