I have this in a pdf and i printed and laminated it so i could take it out to the car with me.

If you have someone to help the whole job can be done inside 1 hour. Jacking up a front wheel as MinniTheMoocha has advised is the simplest.

Have one person with the feeler gauge and the other with the ring spanner and flat blade screwdriver. Follow the sequence in the manual.

After you adjust each valve run through the sequence again checking the clearances.

Note: rotate the wheel only in the forward direction.

MinniTheMoocha and myself did both ours Defender 300 tdi's last Sunday.

The order for checking valve clearance for 4 cylinder 2 valve per cylinder engines is known as "The Rule of Nine". The number of the valve pair rocking and the numbers for the valves that need to be checked add up to nine e.g., 7 & 2 (9), 8 & 1 (9), 3 & 6 (9), 4 & 5 (9) etc.. no need to laminate any paper.
