Before installing pistons in the cylinders be sure to thoroughly clean the cylinder bore, this is absolutely critical for proper ring seal. The rings allow sealing of combustion pressure, they scrape the oil from the cylinder surface and also transfer heat from the piston into the cylinder wall. Ring end gap should be measured with the ring square in the bore on a fresh hone. 3.

Enginebasics is the wiki or wikipedia of car part, repair, how to and tuning information. The oil rings also help the thermal control because it cools the piston by directing oil around it. 4. This is possible because the top ring acts as a barrier. Maximum ring gap is an important part of ring performance in that too much gap results in lost compression, power loss, and ultimately poor oil control. "); One key to a successful engine build is to prevent this from happening. The piston rings are located on the piston. This ring helps the piston work, because during the combustion process it doesnât allow it to lose any pressure. Ring Installation (See Illustration 1) 1. This bank is known as the engine block. The Moss Tech department goes over piston ring installation and covers the importance of spacing the gap in the rings around the piston. Even in a mild case where the ring ends barely touch, the result can be a heavily scored cylinder wall and serious piston-ring-land damage due to this excessive load. If there’s no bevel, install either way in the top groove.
