Tracker 4WD L4-1.6L VIN 6 (1998)
IMPORTANT: The maximum allowable compression pressure difference between any two cylinders is 100 kPa (14.2 psi) at least 250 rpm.
9. Repeat the compression test procedures for the remaining three cylinders.
10. Remove the J 39313 and the compression gage from the engine.
11. Install all four spark plugs and connect the distributor electrical connector.
12. Install the F1 (15 amp) fuse to the fuse block.
Evaluation
^
Normal Operation
The pistons, piston rings and valves are operating normally if the cylinder compression pressure increases quickly and evenly to the compression
standard (1,400 kPa/199 psi at least 250 rpm).
^
Faulty Piston Rings
The piston rings are probably at fault if the cylinder compression is low on the first stroke and tends too increase on following strokes, but does not
reach the compression standard. The addition of oil should improve the compression pressure considerably.
^
Faulty Valves
The valves are probably faulty if the cylinder compression is low on the first stroke and does not increase on following strokes. The addition of oil
will not significantly improve the compression pressure.
