I did a full timing job on my '06 5.4 a couple summers ago. I’m a confident DIY mechanic, so I had no real issues with that. Now, I have an '11 3.5 with the classic phaser startup rattle and a timing-related code (can’t remember exactly, but something like Bank 1 over-retarded).
This truck is high mileage—over 400,000 km—so I’m thinking the timing chain is probably stretched. The 3.5 seems like it should be easier to work on since there’s more room in the engine bay compared to the 5.4… or am I being too optimistic?
Anyone with experience doing both jobs? How do they compare?
They’re definitely different. You’ll need cam hold-down tools for the 3.5 and a way to hold the crank pulley while torquing it, but otherwise, it’s straightforward. Only use Ford parts, or you’ll be doing it twice. Get the full Ford kit, plus any extras it doesn’t include. Also, good time to do spark plugs and the water pump while you’re in there.

That’s how I tackled the 5.4—I even replaced the oil pump. And yeah… I made the mistake of using aftermarket parts and had to redo the cams. Lesson learned.

An oil pump isn’t usually necessary unless you’re having pressure issues. On the 5.4 3V, people upgraded them to help with scored cam caps, but it’s not a must-do on the 3.5.
