how many on here have this engine? after reading about the cam phaser issues and spark plug removal problems, i'm a bit apprehensive about buying one. i found a 2010 f150 5.4 triton with 134k miles in excellent condition, one owner carfax with oil changes about every 8k. truck looks like it was garage kept, but i am wondering if this is an engine i should really avoid. thoughts on this would be appreciated. it would possibly be a truck for my daughter. i do most of my own work and have kept cars alive for a long time, but i am not very familiar with the ford lineup. the cam issue really has me concerned but not sure if it was corrected for that year or if a mechanic would be able to tell if it was "on its way out"
