I had written and humorous response to your post, but yours disappeared and it wouldn't let me post, I can only assume that The Mothership got wind of it and wanted me stopped. Probably permanently. They are probably watching me now, in my pants, needing a shower. But I digress. This family of engine certainly have a reputation to uphold here. If it's not HG failure, chuck in a sprinkling of EGR issues and variably geometry turbo problems, there's even the odd snapped crank as well and one might wonder why anyone would buy one. But buy them they do. Seemingly pouring a little urea into a conveniently placed tank is more trouble than the various engine issues not doing has exacerbated. Ford had terrible problems here in the 1980's with porous engine blocks, they put their head in the sand and hoped it went away which killed the brand. Admittedly the engines they replaced them with would survive a nuclear attack, but the damage was done. The Mothership on the other hand has a well oiled and efficient marketing machine which means it matter not one bit what falls off these machines, people will definitely have another. Their early Autopowr transmissions were dreadful, due, I'm told, to poor filtration. Other brands that used the same transmission had far fewer issues, but Deere did and thus all CVT/IVTs were bad which dragged the values of all brands down fitted with this type of transmission. Now they are flogging their Direct Drive as a viable alternative to a CVT, which is amusing when DD is still a fixed ration transmission just with some fancy software. |
