Part #: 800-069
New set of 12 intake and exhaust valve seals for Datsun 240Z, 260Z, 280Z and 280ZX, 1970-83. These are stock replacement valve seals. If your car is using oil but you do not see smoke or any dripping these seals might be the problem. The engine can pull oil in past these valve seals which shows very little smoke and mostly occurs under deceleration.
These will also fit 4-cylinder "L" series engines.
