05 5.4 3V bad lower end knock
I will say i have been around the block a few times and my 05 FX4 is my 14 or 15 Ford truck and four of them with 5.4 2V this is my first 5.4 3V .Now to be fair i did buy it used as a rebuilder with about 24K on it. Had been hit in driver front or should say looked like it ditched and hit a colvert but did not damage the engine. After i fixed it i noticed that it ' would use a qt of oil in 2500 miles did'nt like that but well within specs but did notice a slite tic in engine on driver side, Talked to mechanic buddie he thought it might be a piston wrist pin. I used lucas oil treatment one time, tic did not go away so did not use it again till about 72k and did it to 20% like it call for,now i should say the tic at time seamed to almost go away but would come back with in a day or two. The tic never got louder and you only would here it at idle . Well today at lunch when i started it i thought the botton end was going to push thru the oil pan. So dejected i started calling my contacks back in Michigan for the takeout engines and finding these thing are selling like hot cakes . Is thair a problem with the 5.4 3V engine ??? or did i hurt my self by using lucus . Looking for some input i have Driven 5.4 2V engine well over 150K and no problems.
Thanks Mike

I had to have lifters replaced in my 04' 5.4L 3 valve.. Mine was bad, but was under warranty when I took it in.. Mine was knocking bad though all the time. When I took it in to the dealer, they knew exactly what it was. There was a service bulletin on the problem at that time. I am not sure that is your problem, but I'd look it up.

I wish i could get off that eazy but it is lower end . My game plan was to get thru the winter and early sping pull the engine and put in a low miles take out and a few upgrades. I got lucky and found a 05 5.4 3V long block (Ford )take out with 5k on it $1600.00 . Will update after i switch out in a couple of weeks.
