Cousin of mine just bought a 06 with the 4.6l in it. I'm not very familiar with this engine, although I have driven a few, and knew that it wasn't for me.
So, a couple questions.
First, do they have the breaking off plug issue, or is this the motor that spits them through the hood if not torqued?
Do they have FPDM issues as well?
Any of the same timing issues as the 5.4l?
I'm having a lot of mixed answers on these questions while searching the interwebs, so I appreciate any input from some fellow members. Thanks.

No breaking plugs, but torque properly:
yes on FPDM. I checked, cleaned and spaced mine away from the frame a little as it was good.

No on timing issues.

Spits them out. When I bought mine, I had my mechanic torque them to 20 ft/lbs, which is over Ford spec, but it seems to be the easiest solution.

Yes, mine stalled on me driving home from work and took a while to start it up again. Ever since I replaced the module, it has not stalled since.

Any engine can have timing issues, but the 2v 4.6 doesn't seem to have the bad track record the 5.4 does. The 3v 4.6 appears to have the same issues the 5.4 does, but those aren't in any 04-08 F150's.

I like the 4.6 2v, it's just a simpler, older, more proven engine. It has some flaws, but they're relatively minor. I have yet to tow with mine, but it's rated for over 6000 lbs, which is plenty for a 1/2 ton IMO. When not towing, it's got a lot of pep to it and I have to intentionally not hit the gas pedal hard or I'd be getting more speeding tickets than I can afford.

So, yeah, the 2v 4.6 is one of my favorite engines in the F150, with only the 4.9L straight six and 5.0 Coyote beating it.

They don’t spit out plugs. That was only on the 97-03 4.6.

I have heard that some 4.6 engines in the mustang have phasers and VCTs for timing but not our trucks . 4.6 l engines do not spit plugs but should be torqued down to prevent loose plugs . Spitting plugs on older engines was because of too few threads in older heads . 4,6l do not have the extended reach problematic plugs either .
I have worked on a few but not enough to have the total picture . 4.6l are not very good at towing as most guys complain of lack of power . I have only worked on one 2002 4.6l mustang but did not go deep on engine so I can only go by what others report . My 81 year old friend has it and the last time it acted up he had accidentally knocked the mini switch on his tuner to a mid position . He is like a sixteen year old with that car .

I read the same about the 4.6 in the Mustangs. I believe there was a 4.6l 3v in the 09 trucks?
I agree about the power. It was quite the difference in power, compared to the 5.4l, in my opinion. Same thing goes for comparing the 3.0l v6 to the 4.0l v6 in the Rangers.

And the same applied to the F150 in that the smaller, weaker engine was more reliable than the larger, more powerful engine.

That may be, but I need the power.
