Peugeot 504 Engine ReplacementRebuilt & Performance Options Available

A rebuilt Peugeot 504 engine typically costs £1,600-£2,400 supply-only, depending on engine code and variant. Diesel XD2 units sit at £1,800-£2,400, while petrol XN1 engines range £1,600-£2,100. Supply & fit adds £600-£1,200.

• XD2 diesel rebuilt: £1,800-£2,400 supply-only
• XN1 petrol rebuilt: £1,600-£2,100 supply-only
• ZMJ V6 Cabriolet: £3,500-£6,000 due to rarity
• Supply & fit service adds £600-£1,200 labour

The XD2 2.3L diesel is widely regarded as the most robust Peugeot 504 engine for classic use, offering strong torque and longevity when maintained. The XN1 2.0L petrol is also reliable if timing chain wear is addressed preventatively.

• XD2 diesel: legendary durability, watch head gasket/liner seals
• XN1 petrol: robust if timing chain replaced preventatively at 70k miles
• Avoid neglected units regardless of engine code
• Regular oil changes critical for all 504 engines

XD2 failures are typically head gasket blowouts or wet liner seal leaks, often triggered by overheating or age-related gasket degradation. These issues commonly appear between 80,000-120,000 miles on original units.

• Head gasket failure from thermal stress and material age
• Wet liner seal leaks cause coolant/oil contamination
• Overheating accelerates both failure modes
• Upgraded gaskets in rebuilt units address original weakness

Yes, if your 504 has collector value (Cabriolet £25k+, clean saloon £5k-£15k). A rebuilt engine at £1,600-£2,400 preserves value and reliability. For rough examples, compare engine cost against total project budget.

• Cabriolet V6: replacement almost always justified by value
• Clean saloon/estate: rebuilt engine enhances usability and value
• Rough project cars: budget engine cost against full restoration spend
• All rebuilt units include 12-month warranty for peace of mind

Yes, but compatibility depends on mounting points, transmission match, and cooling layout. XD2 swaps between saloon/estate/pickup are straightforward; V6 or later XU swaps require specialist adaptation.

• XD2 fits most diesel 504 variants with minimal modification
• XN1/XN2 petrol engines share mounting across petrol variants
• ZMJ V6 requires Cabriolet-specific mounts and cooling
• Always verify engine code compatibility before ordering

The engine code is stamped on a plate on the cylinder block or head, often near the dipstick or timing cover. Common codes: XD2 (diesel), XN1/XN2 (petrol), ZMJ (V6). Enter your reg above for instant DVLA verification.

• Check plate on cylinder block/head near dipstick
• XD2 = 2.3L diesel; XN1 = 2.0L carb petrol; ZMJ = 2.7L V6
• Registration lookup via DVLA confirms exact fitment
• Photos of stamping help specialists verify before quoting

Reconditioned 504 engines are cleaned, inspected and resealed with worn parts replaced; rebuilt units undergo full teardown, machining and assembly with upgraded components addressing known failure points like XD2 head gaskets.

• Reconditioned: cost-effective for sound-core engines
• Rebuilt: comprehensive, upgraded components, preferred for high-mileage
• Both carry minimum 12-month warranty via EngineMarket network
• Rebuilt recommended for engines over 100k miles or with known issues
