🔍 Key Concepts

• Piston ring grooves and drain holes in a trunk piston • Function of an oil control ring versus compression rings • Where a bearing insert tang or thrust washer would normally be located in an engine assembly

💭 Think About

• Look closely at where arrow 16 is pointing in relation to the ring grooves and the interior of the piston. Is it pointing to a hole, a pin, or a plate? • Ask yourself which of the options would logically be found up in the piston crown/skirt area versus down at the connecting rod big end or main bearings. • Consider what path lubricating oil must take after it is scraped off the liner by the oil control ring.

✅ Before You Answer

• Verify whether item 16 is located near the ring grooves or near a bearing surface at the crank end. • Check if the shape of item 16 is a hole/passage through the piston wall or a solid part like a pin or washer. • Eliminate any choices that are normally found only in the connecting rod big end or main bearings, not in the piston head area.
