Porsche Engine Piston Ring Set - Grant P1434

Product Information

An engine piston ring set consists of multiple rings that fit into grooves around each piston. Their main roles are to seal the combustion chamber, regulate oil consumption by scraping excess oil from cylinder walls, and transfer heat from the piston to the cylinder wall. Typically, a set includes compression rings (for sealing combustion gases) and oil control rings (for managing lubrication).

• Excessive exhaust smoke (blue or gray), caused by oil leaking into the combustion chamber.
• Loss of compression and power, leading to poor acceleration and misfires.
• High oil consumption, requiring frequent top-ups due to oil burning inside the cylinders.

About Grant

Founded by Gerald Mitchell McDonald Grant in 1922, Gerald "Gerry" Grant had a fervent passion for the automobile. Gerry Grant realized that engines did not last that long in the early days of the automobile and he capitalized on this by first selling rebuild kits and then going into the piston ring manufacturing business. Grant was involved in all types of Motor Racing from hill climbs to Streamliners to the Indy 500. In 1952, Grant sponsored a specially built Ferrari for the 1952 Indianapolis 500. The car ran well with Johnnie Parsons driving, but it had ignition troubles and did not qualify. After passing in 1952,Grant left his company and legacy to two nephews, Grant and Dick MacCoon which would go on to make their own history. 1955 saw Grant take over the 200 Mile Per Hour Club and for years was instrumental in pioneering high speed driving at the Bonneville Salt Flats in Utah. Running their flathead '32 Roadster at the dry lakes, the brothers gained knowledge in the fact that a piston ring was more than just decoration for a piston. They realized how important the ring was for sealing and helping to dissipate heat under tremendous cylinder pressure. Throughout the years, Grant has been a part of the colorful history of the automotive aftermarket. The Grant commitment to quality product and service began in 1922 and stands firm today as the underlying foundation for everything they do.
