The 7948C Piston Ring Set is specifically designed for Pontiac vehicles manufactured between 1953 and 1954, with a engine displacement of 239 cubic inches. This set includes five cast piston rings, each meticulously crafted to ensure optimal engine performance and longevity.
The top ring in this set is a compression ring, responsible for sealing the combustion chamber and maintaining the proper compression ratio. Made from high-quality material, this ring is engineered to withstand the high pressures and temperatures generated during engine operation.
The second ring is the oil control ring, which works in conjunction with the oil pump to regulate the amount of oil that enters the combustion chamber. This ring is crucial in preventing oil consumption and ensuring proper lubrication of the engine's moving parts.
The third and fourth rings in the set are the oil scraper rings. These rings have a groove on their outer edge that scrapes excess oil from the cylinder walls and directs it back to the crankcase for reuse. This helps to maintain proper lubrication and prevent excessive oil consumption.
The fifth ring in the set is the lower or skirt ring. This ring seals the space between the piston and the cylinder wall, preventing the escape of combustion gases and ensuring proper engine performance.
Each ring in the 7948C Piston Ring Set is precision-machined to ensure a perfect fit in your Pontiac engine. This set is an excellent choice for anyone looking to maintain their classic Pontiac's engine performance or restore a vintage vehicle to its former glory.
