Vauxhall Cavalier Camshaft Replacement Parts

Yes, all Vauxhall Cavalier engines use at least one camshaft — it is a fundamental part of every petrol and diesel engine fitted to the Cavalier across all generations, controlling the opening and closing of the valves. The Cavalier Mk1 (1975–1981), Mk2 (1981–1988) and Mk3 (1988–1995) all carried camshafts as standard. Some Cavalier engines are single overhead cam (SOHC) and some are twin cam (DOHC), so the exact number and type of camshafts fitted depends entirely on which engine your car has.

Both years sit within the Cavalier Mk3 generation (1988–1995), so there is a reasonable chance the camshaft could be compatible — but only if both cars share the same engine code, since Vauxhall fitted several different engines across the Mk3 range, including the 1.6, 1.8, 2.0 SOHC, and 2.0 16v DOHC units. The engine code is the single most reliable guide here, and you should supply it to the breaker so they can match the correct camshaft rather than relying on year alone. Never assume fitment based on year without confirming the engine code matches.

The Mk2 ran from 1981 to 1988 and the Mk3 from 1988 to 1995, and while some engine families carried across generations, this is a generation boundary where you should not assume interchangeability. Even where the same engine family appears in both generations, there can be differences in camshaft profile, timing belt compatibility and ancillary fitment that make a straight swap unreliable. Confirm the engine codes on both vehicles with the breaker before ordering — this is exactly the kind of cross-generation question they are best placed to answer with your registration to hand.

Trim level makes no difference whatsoever to camshaft fitment — the camshaft follows the engine, not the badge. A GL, CDi, SRi or GSi fitted with the same engine code will use the same camshaft, whereas two cars wearing the same trim but with different engines will need different camshafts. Focus entirely on the engine code (found on your V5 or via a VIN check) when sourcing a replacement, and ignore the trim name entirely.

The 2.0 16v engine fitted to the Cavalier Mk3 is a twin overhead cam (DOHC) unit, meaning it has two camshafts — one operating the inlet valves and one operating the exhaust valves. When sourcing a replacement you will need to specify whether you need the inlet or exhaust camshaft, as they are different parts. Supply your engine code to the breaker to make absolutely sure they pull the correct one from the donor vehicle.

Yes — the diesel engine fitted to the Cavalier Mk3 has its own camshaft specific to that unit, and it is not interchangeable with any of the petrol camshafts. Fuel type is one of the key fitment factors here, so always make clear to the breaker whether your car is petrol or diesel alongside your engine code. Mixing up petrol and diesel camshafts will result in a part that simply will not fit.
