Routine service schedule and not many items in the list that need to be done. Only a filter and engine oil change. The mileage is a bit overshoot from the recommended interval set by the BSI alas 2.5K extra still within the threshold. Today is the return of Amsoil as the lubricant brand of choice.
This is supposedly 20 minutes job tops but it was stretched to 2 hours due to leaks found around the valve cover (some say: rocker cover). Looks like the rubber gasket needed replacement. Dismantling it was an easy job as it was hold by two 10mm nuts.
