PISTON RING SET 4 CYL 0.50 (Toyota TY00591-17852-81)

TY00591-17852-81: A worn piston ring set can allow combustion gases to escape past the piston, reducing compression and causing power loss. This aftermarket replacement part references Toyota as the OE maker and cross-references part number TY00591-17852-81. The piston ring set is a retaining ring type component that seals the gap between the piston and cylinder wall. A common failure consequence is increased oil consumption as the rings lose their ability to scrape oil from the cylinder surface. During operation, the rings must maintain consistent tension to prevent blow-by and maintain cylinder pressure. The item ships at approximately 0.33 pounds. Verify the serial number or application, then call (562) 693-7748.
