The Taurus was generally unreliable at first. Bristol Beauforts were grounded in 1940 for 3 months as the crews almost mutinied (but still agreed to do one important sortie in this time). The Taurus then underwent rework creating the later versions. It was still not "good" so the UK Beaufort Mk.II was re-engined with the P&W R-1830 Twin-Wasp. Australian Beauforts had the P&W R-1830 from new.
By the time the Albacore came into service, the Taurus was "fixed" & much more reliable but I suspect they were just using up obsolete equipment.
