One thing that how to doesnt tell you is it is better to buy a bolt an inch longer than the crank pulley bolt to get it started when reassembling. There is a chance that you can strip out the thread in the crank if you dont do this due to not enough threads being engaged. Otherwise it is a very good right up.
When I did my cam change etc I didnt bother with the dropping of the sump. However this method can have a few dangers & is not recommended for the inexperienced.
