Replacing Complete Engine or Cylinder Block

Cylinder Block
Instead of replacing the complete engine, use a materials kit that includes cylinder block, pistons, gudgeon pins and piston rings.

If the cylinder block is replaced use new main bearings.

Note! The new cylinder block (including pistons, gudgeon pins and piston rings) or the engine, will be the latest variants. (If parts from the older cylinder block do not match parts on the new cylinder block, then other parts may need replacing).

Refer to the Content, variant and chassis number range for extra material requirements.
