The one thing that I liked on the new 46 NT's is the tight pinch each engine had. And no missing parts, like glow plugs.
Getting around the ban on chrome plating in Japan probably had a big role in the decision to move manufacturing too......if OS is going to use chrome like the other 99% of engine companies.
Not likely. Enya metal products is still very much in business and uses hard chrome in several of their engines. Their AAC constructed engines are fantastic. By the time an Enya is worn out, you would have worn out a dozen OS's. Enya also uses what they call ABN but is actually a form of Nikasil - they just don't call it that due to Nikasil being a trade name.
