EVALUATION OF TEST RESULTS

According to the MKIV Bentley manual, the compression specifications for the 12v VR6 engine are as follows (the values you obtain during your test will depend on both the condition of the engine and the accuracy of the pressure gauge used):


- new ------------------------------------------------------ 10 to 13 bar (147-191 psi)
- wear limit ------------------------------------------------ 7.5 bar (110 psi)
- maximum difference between cylinders ------------------ 3 bar (44 psi)
