Land Rover Technical Library — Engine Specs & Service Data

Our technical library is a free, independent reference for Land Rover engine specifications — built to answer the questions owners and specialists ask most often.

Timing chain or belt? — definitive answers for every engine, with service intervals and wear indicators
Oil capacities & grades — correct oil type, quantity, and filter specs for each engine
Service schedules — model‑specific maintenance intervals from the factory, with real‑world caveats
Engine code decoding — where to find your engine number and what it tells you
Torque specifications — critical fastener torques for common jobs

All data is cross‑referenced with manufacturer TSBs, workshop manuals, and specialist interviews [EM‑INTERVIEW]. Use the library to check a spec before you buy parts or to confirm the correct service regime for your vehicle.

This index covers the most‑requested technical data. If you need a spec that isn't listed, use the Diagnostic Wizard or contact us to request it.

How to Use This Library

Find your engine code – start with the engine code decoder or engine number location guide to confirm which engine you have.

Check the key spec – use the index above to jump directly to timing chain type, oil capacity, or service schedule for your engine.

Understand the caveats – each page includes real‑world notes from specialists [EM‑INTERVIEW], so you know when the official spec doesn't tell the full story.

Link to the data – every page is a standalone reference you can cite or bookmark. For a full methodology, see our data methodology and data verification standards.

Where Our Technical Data Comes From

Every number on this site is verified against at least two independent sources:

Manufacturer published data – JLR workshop manuals, TSBs, and official specifications.
Independent specialist interviews – cross‑checked with 12 vetted JLR specialists who rebuild these engines daily [EM‑INTERVIEW].
Real‑world enquiry data – 24,650 UK quote requests that frequently contain notes on incorrect specs [EM‑VERIFIED].

All technical pages are reviewed on a rolling schedule – see the Corrections Log for the last update date. If you spot an error, let us know and we will investigate and correct it.

Frequently Asked Questions

Is the technical data on this site official Land Rover data?

No – it is independently sourced and cross‑verified. We combine manufacturer published data with real‑world specialist knowledge and our own enquiry data to produce a reference that is more practical than a factory manual alone.

How often is the technical data updated?

We review technical data on a continuous basis, with major updates annually. Each page shows the last verification date in the summary box. If a TSB or recall changes a spec, we update it promptly.

Can I use this data for non‑Land Rover vehicles?

Some pages cover engines shared with Jaguar (AJ‑V8, Ingenium) or BMW (M47/M57), but the site is focused on Land Rover and Range Rover applications. For other brands, see our BMW or Mercedes sites.

What if the spec I need isn't listed?
