138,200mi on my '05 5.4 3v...just changed the plugs and it recently devoloped a rear main seal leak, not too bad yet (not bad enough to go through the hassle of changing it!)

Had 180k on my 05 STX with the 4.6 before I traded it in last year. Zero issues with motor and trans. Currently have 120k on my 07 lariat with the 5.4. It runs good as well.
