L-series (20T2N)
2.0 L · inline-4 · turbocharged · diesel · 1994–present
Also known as: 20t2n, 20t2r, l-series diesel, rover l-series, 2.0 rover diesel, 20t2i
Rover's 2.0 turbodiesel — the L-series — and, unexpectedly, the diesel in the European Honda Accord and Civic.
⚑ It is a Rover engine in a Honda, which is the whole reason to know its name. The two companies were partners, and the diesel Hondas of that era carry it. Honda advice does not apply and Honda parts mostly do not fit — an owner searching for a Civic diesel finds a generation of results about the later N22A, which is a different engine from a different company.
It is direct-injected with a rotary pump — modern for its day, pre-modern by every current standard: no common rail, no particulate filter, nothing to regenerate.
Its known item is the cylinder head, which cracks between the valve seats on engines that have been overheated. Coolant loss with no external leak is the tell, and it is testable before anything is stripped.
The timing belt drives the injection pump, so a belt service is the specialist job it always is on this generation of diesel, and getting the pump timing back is the part that takes the skill.
Parts and specialist knowledge are both thin now, which is usually what decides whether one of these cars is worth keeping.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
