Seal changed
The seal from the turbocharger to the oil return line was altered from being a full face gasket (1) to a beaded sheet steel seal (2) with rubber coating on both sides. The form of the bolt holes was also changed.
These alterations led to improvement of sealing of the oil return between the turbocharger and oil return line.
