Yes!! Bachelor for life!
I read around that the 4.6 Ford engine was designed to go to out to 600k+ with oil changes without any timing service. What takes the car out is the transmission. The 4r70w will need a rebuild around 200-250k.
When transmissions go out people just get rid of the car and don't try to rebuild it. My passion is actually the transmissions. I have already rebuilt the valve body and updated everything inside it.
Thank God for Sonnax!! I'm looking to buy some nice hard parts and build up a 4r70w all out no expense spared right in my living room and have it as a spare in the my closet. Will use PCT torque converter next time around.

Anyways, if you buy the Ford OEM timing kit it comes with the iron tensioners. My 2004 had plastic tensioners with no gasket but they didn't have any issues either. And if you look closely at the old guides they still had lots of "meat". At 390k miles I still had time to spare. Oil changes on time was critical to my engines longevity.
