The objective is to flush the valve and skip exactly as much as necessary for the valve lubrication. The oil cap prevents the passage of excess motor oil.
The mash cap is made of rubber. Over time, this rubber is worn, relaxed, cracked, loses its properties, so that the oilseed cap starts to miss more oil than is required.
The wear condition of the cap-cap may be:
1. Increased oil consumption
2. Stable smoke from the engine's tailpipe and the gas pedal
3. If the hand is to the exhaust pipe, it shall remain the drip of the instill skin
Replacement of dilapable oil caps is not considered to be a major repair of the engine. It is only when there is experience to change the oil caps with their hands.
