Inspect

  1. 11. Calibrate pressure loss tester • Connect to compressed air system

Note. Follow manufacturer's instructions

  1. 12. Attach pressure loss tester • Engage 1st gear and apply parking brake • Screw connector into spark plug thread of cylinder 1 • Apply compressed air to cylinder 1

Note. Wheels must be in contact with the ground

  1. 13. Test pressure loss • Take pressure loss reading – The maximum permissible pressure differential between cylinders is approx. 10% – Maximum pressure loss of a cylinder is 25% • Take note of any visible escape of compressed air – Intake manifold, exhaust manifold, crankcase • Take not of any bubble formation in the coolant compensation tank
  2. 14. Perform compression test in a similar manner for cylinders 3, 4 and 2
