WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The cylinder block is an aluminum alloy casting with cast iron cylinder liners.

Oil ways to each main bearing supply oil to lubricate the main bearings and also to supply, via a cross drilling, the connecting rod big end bearings.
The cylinders are numbered as shown below, with cylinder 1 at the front of the engine:
