Reference section
Jaguar Mk2 Knowledge Base
Beyond the upgrade guides, this is the reference section: how to buy a Mk2 well, where they rust, how the legendary XK engine works, and the racing history that made the fast-road Mk2 what it is.
Buying a Jaguar Mk2
Why rust matters more than mileage, the engine and gearbox checks, 3.4 versus 3.8, provenance, and how to avoid a money pit.
Rust & where they rot
Sills, floors, jacking points, valances, wheelarches, boot floor and suspension mounts — the structural areas that decide a car's fate.
The Coombs Mk2 & competition history
John Coombs, the saloon racers that beat everything around 1960, and the conversion that became the template for every fast-road Mk2.
The XK engine explained
The twin-cam straight-six of Le Mans fame in its 2.4, 3.4 and 3.8 forms — how it is built, and why it responds so well to tuning.
More reference articles are in preparation. For work on the car itself, see the upgrade guides.
