Timing Component Alignment MarksCamshaft Timing Tool:
To place the Jaguar 4.2L engine "in time" the No. 6 (front) cylinder must be at TDC and the timing notch on each camshaft must align with service tool C3993. 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
