As said the oil should be 5/30W not the 10W/40 or 30 as mentioned above, although as to whether this would be causing the tapping or not is questionable, but as said it has been known to stick tappets.


5W/30 is Fords reccomendation despite Haynes and Shawspeed etc saying 10W/40 can be used.

As said you probably need to do the valve clearances.

This is the setting specification, something no one else has mentioned either is it's crucial it is done with the engine cold:

0.20MM (Intake)

0.34MM (Exhaust)

The method for achieveing this is mentioned above.
