We also own a Daihatsu Feroza. We have the same problem with the engine before. Gusto namin ng surplus either gas or diesel pero wala kaming makita sa mga surplusan. So we ended up with an engine overhaul. For now ok na siya. Medyo maselan po sa parts ang Feroza since wala ng support sa previous dealers niya. swertihang hanap sa Banawe. An example is the metal fuel filter which took us 1 year to find one (3 years old na ang dati). Goodluck with your engine search.
