Answer 1

Sleeving is taking metal tubes that fit inside of the cylinder walls and pushing them down into the engine block, which is the larger hollow metal structure around the rotating parts. It’s job is really to hold everything in place. The cylinder head, bolts down onto the top of the engine block, or deck surface. It controls the airflow in and out of the cylinder as it cycles from intake to exhaust.
