Answer 1

Answer:

B) Technician B only

Explanation:

Slap is caused when engine is cold

Piston slap is moves ups and down in the engine block.Air and  fuel explodes inside the chamber.Piston is connected to pin.

The Piston can be sufficiently enormous with the goal that the cylinder rocks starting with one side then onto the next to cause the cylinder slap. Aluminum squares will in general effectively capitulate to this issue than others.  

Piston that experience increasingly chilly leeway acquire speed when the cylinder moves from the minor to significant push side and this causes the cylinder slap.
