Do they manufacture their own now or do they still source them from a "partner"?
With GM, I believe they are all designed, engineered and built in-house. Technology and proven designs are often shared ("borrowed") from partner companies (Holden, others?).
1.6 is definitely derived from Isuzu. Those are engines that OPEL was developing with Isuzu in Europe.
These GM diesels are bit better in the last 10-15 years. Before that, they were atrocity.
