Every 320d has a story. Make the right call with clear data, real-world costs, and honest guidance from UK specialists.
Can It Be Repaired?
Buying This XJ 3.2 V8? Check These First
Buy If
- Post-2000 model with steel-liner engine (Nikasil issue resolved)
- Timing chain tensioners upgraded to metal units
- Full service history with regular oil changes
- No cold-start rattling (timing chain tensioner health)
- No coolant loss or overheating history (cooling system health)
Avoid If
- Pre-2000 model with original Nikasil engine - assume it's a liability
- Cold-start rattling and no timing chain history - budget for tensioner work
- No service history - the AJ26 is sensitive to oil quality
- Coolant loss or overheating history - cooling system damage may have occurred
- Excessive rust - X308s are known for corrosion, particularly around wheel arches, sills and front spring mounts
Closing Verdict
The XJ 3.2 V8 is Jaguar's entry-level V8 in the X308 generation - a 3.2-litre AJ26 engine producing 240 bhp and offering a superbly quiet and refined ride. The engine is a significant departure from the straight-six and V12 engines it replaced. However, it has two critical vulnerabilities: Nikasil cylinder liners on pre-2000 cars (which can fail catastrophically) and plastic timing chain tensioners (which degrade and can cause engine destruction). Post-2000 cars with steel-liner engines and upgraded metal tensioners are the only safe choices. With typical X308 values ranging from £3,000 to £8,000, an engine replacement is a major financial commitment - a well-maintained post-2000 example with documented service history is the safest choice.

Buying Checklist
Before you buy a used Jaguar XJ 3.2 V8 (or before you commit to an engine replacement), check these:
Engine Type
Confirm post-2000 with steel-liner engine (Nikasil issue resolved) - see the map above
Cold Start
Listen for rattling or clattering (timing chain tensioner warning)
Service History
Including regular oil changes (critical for timing chain longevity)
Coolant Level
Check reservoir when cold; any low or loss may indicate cooling system leaks
Coolant Leaks
Inspect around coolant reservoir and thermostat housing for cracks or residue
Rust
Check wheel arches, sills and front spring mounts for corrosion
Electrical Systems
Test all electrical functions; PDUs and wiring can be problematic
Engine Warning Light
Have codes read; unresolved issues may indicate timing, cooling or sensor problems
MOT History
Check for emissions-related failures and corrosion advisories
Buy smart. Drive with confidence.
A few checks today can save thousands tomorrow. Use this checklist to avoid the most common 320d pitfalls.
