Toyota Tundra oil leak from overhead cam requiring engine removal for repair on Toyota Tundra

Some Toyota Tundra owners report experiencing oil leaks from the overhead cam, often attributed to cam tower leak issues commonly found in models equipped with the 5.7L V8 engine (3UR-FE). These leaks can result from worn or improperly sealed gaskets, leading to oil pooling around the engine block or dripping onto other components, with noticeable oil stains in the engine bay or on the ground. Repairing this issue typically requires accessing the camshaft housing, which involves removing various components and can be complex, often resulting in repair costs upwards of $3800. Many owners find the repair challenging and not suitable for DIY due to its complexity. Although Toyota has addressed certain recalls, the widespread nature of cam tower leaks suggests a significant design flaw. Regular maintenance and inspections are recommended to detect these leaks early and prevent more severe issues.
