There are numerous sources for small leaks on the 1Z, most of them minor. The valve cover and the pipe from the CCV back to the block are probably the most common ones. Oil pan gaskets can leak with age, too, as can front and rear main seals. The seals take more work to replace, but none of the leaks are catastrophic.
