Toyota oil leak

Some 2005-2007 Toyota Tundra vehicles equipped with the 1GR-FE engine may display a small oil leak located where the Bank 1 cylinder head, engine block and timing cover meet. Inspect this area for signs of the oil leak. Use an oil dye to confirm the source of the leak.

Remove and reseal the timing cover if the leak is found.
