The tensioning rail of the 4-cylinder gasoline engine is wider at upper end (B) and has no bore in upper part (arrow).

On the other hand, the tensioning rail of this engine is pointed at upper end (A) and has an 6 mm bore in upper part.

In addition, a lug has been cast-on to lower end of tensioning rail to avoid confusion.
