Jaguar AJ-V6

The Jaguar AJ-V6 is a modern all alloy 24 valve V6 engine with two stage variable valve timing on the inlet cams.
It comes in 2.5ltr and 3.0ltr capacities and came in both transverse (Jaguar X-type) and longitudinal (Jaguar S-type) configurations. The Jaguars S-type application also benefitted from a three stage variable length inlet tract system.
The AJ-V6 is a development of the Ford Duratec V6 which itself is a development of a Mazda engine.
It employs a timing chain rather than a cam-belt and the block is constructed in such a way that the lower portion of the block is a separate structure and creates a girdle type arrangement incorporating the main bearing caps, greatly increasing rigidity.

There are a number of important differences between the transverse configuration and the longitudinal configuration as follows:

Adapting the Engine to Fit

The following is based on my experiences with my Jaguar S-type sourced engine and manual transmission and its adaption to fit to my 1971 Reliant Scimitar.

Engine Mount / Remote Oil Filter

If you are installing the engine in a rear wheel drive / longitudinal orientation then it makes sense to look at the S-types stock engine mounts. But the left hand mount on the S-type version is a large bulky item incorporating oilways and mountings for the standard oil cooler and oil filter mounting. It is pretty much guaranteed to foul on something. Here is how I got around it.
