Hi the 4.2 Ser I E type has the timing marks on the crankshaft damper at the front of the engine. These should be aligned to the timing pointer which should be attached to the front of the sump.
If the pointer is missing give me a shout as this is one of the many parts that i have had remanufactured.
Kind regards

The timing marks do not settle this problem because with the pointer at TDC on the damper it can relate to either no 1 ( rear) or 6 ( front) firing. If the cam covers are off, there is no problem : with the pointer at TDC the valves of the NON-firing cylinder will both be slightly open. If the cam covers are on, then I suggest you get someone gently to turn the engine over on the front pulley bolt, when you will be able to feel whether it is no 1 or 6 on the compression stroke by putting your thumb over the spark plug hole. Whiver is on compression is coming up to firing, and you can affix the flywheel accordingly
