1. XD2 Head Gasket Failure
Why Peugeot 504 Diesel Engines Overheat
Affected Models
Peugeot 504 GLD, GR, Pickup, Familiale (1975-1988, XD2 Indenor 2.3L Diesel)
Typical Failure Mileage
80,000-120,000 miles
Root Cause
Cylinder head warping under thermal stress combined with original gasket material degradation; exacerbated by cooling system neglect.
Repair Options & Estimated Costs (UK ranges)
| Repair Tier | Dealer Price | Specialist Price | What It Involves | Longevity / Suitability |
|---|---|---|---|---|
Minor - Gasket Replacement Only Minor | £800 - £1,200 | £550 - £850 | Remove cylinder head, replace gasket, reseal liners | Short-term fix only; head may warp again if not skimmed |
Intermediate - Head Skim + Gasket Intermediate | £1,200 - £1,800 | £850 - £1,300 | Head removed, machined flat, new gasket, liner seals replaced | Viable if block is sound; 40-60k mile expectation |
Full Replacement - Rebuilt XD2 Engine Best Value | £2,800 - £3,600 | £1,800 - £2,400 | Complete rebuilt unit with upgraded gasket, tested liners, bench-run | Best value for high-mileage 504s; 12-month warranty included |
Our Recommendation
Best next step for xd2 head gasket failure
On a classic 504 valued £5k-£15k, a full rebuilt XD2 at £1,800-£2,400 offers better long-term value than repeated gasket repairs. We recommend replacement if the engine has covered over 100k miles or shows liner seal leakage.
Don't Let Engine Failure Write Off Your Peugeot 504
From XD2 head gaskets to ZMJ oil pumps, Peugeot 504 engines have known failure points - but replacement doesn't mean writing off your classic. EngineMarket connects you with UK specialists who supply rebuilt units with upgraded components addressing the original weakness. Compare prices, check warranty terms, and arrange supply & fit nationwide - all without the main dealer premium.

FAQ
Peugeot 504 Engine ReplacementFrequently Asked Questions
Question 1
How much does a Peugeot 504 engine replacement cost in the UK?
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.
Key points
- • 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
Question 2
Which Peugeot 504 engine is most reliable for classic use?
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.
Key points
- • 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
Question 3
What causes Peugeot 504 XD2 diesel engines to fail?
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.
Key points
- • 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
Question 4
Is it worth replacing the engine on a classic Peugeot 504?
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.
Key points
- • 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
Question 5
Can I fit a different engine code in my Peugeot 504?
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.
Key points
- • 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
Question 6
How do I identify my Peugeot 504 engine code?
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.
Key points
- • 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
Question 7
What's the difference between reconditioned and rebuilt Peugeot 504 engines?
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.
Key points
- • 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
Question 8
Do Peugeot 504 engine specialists offer supply and fit?
Yes, many UK specialists in the EngineMarket network offer supply & fit for Peugeot 504 engines, handling delivery, removal, fitting, fluids and commissioning - essential for owners without classic car workshop access.
Key points
- • Supply & fit adds £600-£1,200 to engine price typically
- • Specialists understand 504-specific mounting and cooling quirks
- • Warranty can cover parts and labour when arranged together
- • Nationwide network covers most UK locations
Question 9
How long does a Peugeot 504 engine replacement take?
Supply-only rebuilt engines typically dispatch in 2-4 weeks after order confirmation. Full supply & fit jobs usually complete in 3-7 working days once the engine arrives at the fitting garage, depending on variant complexity.
Key points
- • Rebuilt engine build time: 2-4 weeks average
- • Supply & fit installation: 3-7 working days typical
- • ZMJ V6 Cabriolet may require longer due to specialist handling
- • Delays possible for rare cores or high-demand periods
Question 10
What warranty comes with Peugeot 504 replacement engines?
Every rebuilt, reconditioned or remanufactured Peugeot 504 engine supplied through EngineMarket carries a minimum 12-month unlimited mileage warranty from UK specialists. Terms vary slightly by supplier - always confirm before ordering.
Key points
- • Minimum 12-month warranty standard on network rebuilt units
