    If it's a 1993 model, I reckon it's 12-valve. The switch to multi-valve was around 1997, IIRC.

    By the way, the multi-valve is not 24-valve, it's 30, as in 5 valves per cylinder. They're easily identifiable, as the engine cover has "5-Valve" emblazoned across it.

    Hope this helps.

    It may well be DOHC, but your question was how many valves it has, and like I said, unless it's got a badge saying 5-valves (per cylinder), then it's a 12-valver.

    's. After our chat I went to the garage, they stated that our engines (AAH)
    was 24v with Doch

    That confirms what I said, that Corne's engine is a 12-valver.
