Some 2005-2008 Toyota Tacoma models equipped with the 1GR-FE engine may have a small engine oil leak located where the Bank 1 cylinder head, engine block and timing cover meet.
The use of an oil dye and UV leak detector light can help to pinpoint the leak.
If the leak is confirmed at this location, remove and re-seal the timing cover.
