Timing Component Alignment Marks
To place the Jaguar 4.0L or 3.6L engine "in time" the No. 1 cylinder must be at TDC and the timing notch on each camshaft must align with service
tool 18G 1433A. When these conditions are met the engine is said to be "in time".
NOTE: Jaguar does not provide precise timing marks for the engine. Correct engine timing is achieved when the above conditions are met. Refer to
Camshaft : Service and Repair
See: Engine, Cooling and Exhaust/Engine/Camshaft, Lifters and Push Rods/Camshaft/Service and Repair
CAUTION! Incorrect setting/installation without the use of special tools could damage or break the camshafts. Valves could also be bent through
contact with the piston crowns. Always note installation instructions and use specified special tools, procedures, and sequences.
