5.4 Triton engines

[Juneau4]

 Wondering if anyone here has had any experience with the Ford 5.4 Triton engine. I'm thinking about getting an older Ford (2003) 58,000 miles, but I've heard -read- that there can be some plug problems.

I have a 2004, I'm not a Ford vs Chevy guy, and all I can say is:
 

NO NO NONO NO NO NO NO NO NO NO NO NO NO NO NO 

 

NO NO NO NO NO 

 

NO.

Plug problems, cam phaser problems, engine sludge problems, knock problems, tick tick tick tick problems, problems problems problems.

I have an 2008 Super Duty  Zero problems   The 5.4 has been a good engine   There is a problem with spark plugs, easy fix if they are not seized in the cyl head.   Call a Ford service manager and they will give you an honest opinion and if you give them the vin# they can tell if Ford has already changed the plugs.

I had a 2000 Expedition with the 5.4 2 valve engine. Sold it at 175,000 a little bit ago. I replaced the plugs at 96000 as I bought it used and never had a plug problem. You can get upgraded plugs. Had to replace a couple COP'S, but Truck was good to me other wise.

 

You said 2003, that was a different engine than the 2004 5.4 3v(guess the limited build Heritage f150's for 2004 would of had the 2v). The 2v had plugs that loosened and in the 3v they were plugs that stuck in when replacing. Guess they over compensated. I also never had phaser or sludge issues.

I had a new 1999 f150 w 5.4. New head gaskets at 15k, new motor at 45k. Blew spark plug out cylinder at 85k. You can guess my opinion. Never ford truck for me again. ( love my 12 Ford Fusion car though).

I have a 2003 FX4 with 180,000+ on it. It is the 2 valve motor. I had to replace the motor about 14 months after I bought it because of a bad rebuild before I bought it, the oil pump went out and they drove it too long.  The line bore was out. There is no plug trouble with this motor. I have replaced the coil packs and installed new bulbs on it, that is it besides the motor.
