The problem with the statement is that Camit did build the Jabiru engines too, so they really built them all but Jabiru are built to Jabiru spec. I'm amazed at the amount of people that have shown other ways of making Jabiru engines reliable but these mods are not allowed to be done but Jabiru continue with their nonsense and from the latest service letter their seems to be no change to Jabiru attitude after CASA intervention ( blame fuel, pull heads off at service ) , I am a motor mechanic and originally worked on BMC, when Leyland Australia built their own designs they made a lot of mistakes but it was an early mistake they did not rectify properly that destroyed them, it was the Morris Nomad, a dud Oz design engine and a dud gearbox, the warranty work was huge, the Kimberly and Tasman were not as good as the Austin 1800 and the Nomad was a disaster after the successful Morris 1100, the Marina and P76 were also riddled with warranty problems but mainly outsourced parts switches, gauges and alternators which had been occurring since the Nomad, the Mini was the best but the early ones were better. All could have been so different if when mechanics told engineers what the problems were and how to fix them but they had reasons not to and continued the patch up. The problems were obvious to mechanics. The Jabiru story is unfolding and if they keep their head in the sand and don't listen and act they will loose all support and finish up like Leyland. The Leyland products were ahead of their time and potentially good vehicles, the originals were better than the improved version, sound familiar ! Leyland introduced a Buyer Protection Plan to improve their image but it caused more pain for dealers as the dealer had to provide a courtesy car during warranty work, this usually emptied the used car lot each day and at the dealers expense.
After that I worked on Datsun and Honda. Constant improvement was obvious and no hesitation to take on modification advice. Look at Honda now ! A far cry from the Zot, Scamp and the original Civic, which in its standard form could match a Mini Cooper S in performance with a smaller engine. Datsun copied the BMC engine and made it superior.
