Peugeot J5 Cylinder Head Replacement Parts

The Peugeot J5 was produced from 1981 to 1994, and while it carried the same basic platform throughout its life, ancillary and mounting details on the cylinder head can vary across that production run depending on engine code and fuel type. The engine code is the single most reliable guide here — check your V5 or run a VIN check to get it before approaching a breaker. Give that code to the breaker and they can compare it against the donor vehicle to confirm whether the heads are a true match.

No — petrol and diesel cylinder heads are fundamentally different in design, combustion chamber layout, and compression ratio, so they are not interchangeable. Always confirm your fuel type alongside your engine code when requesting a quote from a breaker. Mixing up fuel types is one of the most common fitment mistakes on commercial vehicles like the J5.

Body style — van, minibus, or chassis cab — does not affect cylinder head fitment; what matters is the engine fitted to the vehicle. Two J5s of completely different body styles but sharing the same engine code will use the same cylinder head. Focus on confirming your engine code with the breaker rather than describing the body style.

The J5 ran as a single generation from 1981 through to the end of UK production in 1994, so there is no named facelift generation boundary to cross here in the way you might see on a passenger car. That said, Peugeot did make running production changes during this period, and whether a 1992 head bolts straight onto a 1989 block without modification is something you should confirm with the breaker against both engine codes. Supply your engine code and the donor vehicle's engine code and let the breaker compare them directly.

Yes — engine displacement and engine code directly determine cylinder head specification, so a head from a 1.8 engine will not be the same as one from a 2.0 or 2.5 unit. The engine code is the definitive reference and overrides any assumption based on year or model badge alone. Check your V5 or a VIN check for the exact engine code and give that to the breaker when requesting a quote.

Trim level does not affect cylinder head fitment on the J5 — the head follows the engine code, not the badge or equipment level. You may find that ancillary items such as brackets or sensors differ between specifications, but confirm those details with the breaker against your registration rather than assuming they will match. The core cylinder head itself is determined entirely by the engine fitted, so that is all you need to focus on.
