If they are saying it is indeed piston slap yes demand to get it fixed they arent going to want to because it is neither cheap nor easy so be ready to argue. Piston slap occurs because an automobile manufacturer designs and/or manufactures a defective engine in which the clearance between the piston and cylinder bore is too great. Essentially, the piston moves sideways and slaps or knocks hard against the cylinder bore and causes damage to the engine pistons and cylinders, excessive smoke emissions, excessive oil consumption, carbon buildup on piston heads, decreased mileage, and a loud and obnoxious slapping or knocking noise, all of which diminishes vehicle resale value in the trade.
Apparently some dealerships are saying it is 'normal' and not giving the consumer a work order, even when asked to do so. If this happens to you be sure to keep the following information for your records:
1. Date of repair attempt
2. Time of repair attempt
3. Service writer/managers name**
4. Name of person refusing work order**
5. Service tech's name refusing to do work**
6. Any other items/notes/observations to show proof you were there
** - Write down names in front of the person.
Good luck let us know :)
