Cheap Peugeot 306 Cylinder Head

The 306 ran from 1993 to 2002 in one continuous generation, with a significant facelift in 1997 that updated the front end and some mechanical ancillaries, so a head crossing that 1997 boundary needs careful checking. The engine code is the single most important detail — if the donor and recipient share the same engine code, fitment is far more likely, but changes to ancillary ports, water galleries, or mounting points around the facelift year mean you should confirm the specific part number with the breaker against your registration before buying.

No — petrol and diesel cylinder heads are entirely different parts and are not interchangeable under any circumstances. Always tell the breaker whether your engine is petrol or diesel, along with your engine code from your V5 or a VIN check, as this is the most critical information they need to match the correct head.

Trim level does not determine which cylinder head you need — what matters is the engine code fitted to your car, which can vary across trims. For example, a 306 XS and a 306 GTI-6 use different engines entirely, so the heads are not interchangeable, but that is because of the engine, not the badge on the boot. Give the breaker your engine code rather than your trim name, and expect no cosmetic differences between heads from different trim levels.

For a cylinder head specifically, the gearbox type does not directly affect fitment, as the head sits on top of the engine block and its compatibility is governed by the engine code rather than how drive is transmitted. That said, always confirm with the breaker using your exact engine code, as ancillary differences unrelated to the gearbox could still apply.

Body style has no bearing on cylinder head fitment — the head is matched to the engine, not the shape of the car. As long as the engine code matches between donor and recipient, the body style of the breaker's vehicle is irrelevant, though you should still confirm the full specification with the breaker against your registration.

The 1997 facelift is the key boundary to be aware of here, as Peugeot made updates to the 306 around that point that may have affected ancillary components. If the engine code on the post-1997 donor matches yours exactly, there is a reasonable case for compatibility, but whether any ancillary or porting changes were made mid-production around that facelift is something you should confirm with the breaker against both registrations before purchasing.
