Rid yourself of the pain in the ass (aka SPI) before it drops a valve seat. Your ZTS will never die cuz it has a Zetec (they are what I'd like to call bullet-proof)
123k? My best guess is that its getting ready to drop a valve seat. From personal experience, these motors seem to drop seats in the 110k-130k miles range. I'm shocked mine made it to 154k before dropping. You don't see many SPI's last to the mileage mine has on it.
