Default Engine replacement 2004 F150

Well, after 78,000 miles, it looks like I will either have to get my F-150 rebuilt or buy a new one.
My question is, will the 05-09 engines work in the 04? If so, where can I get them besides Ford.
Thanks!

I just got mine back last week with a new engine also. My original one had no compression in 4 cylinders. Have the Ford dealer install a new one if you got the $$. I paid $6330 for the new engine with a 100k mile warranty and new catalytic converters. Mine died at 86k miles.

wow yall must have had bad luck or been hard on em or somethin, ever ford i have ever known personally has gone at least 150,000 miles or more without any work, i know ford isnt perfect and will screw one up every now and again but i thought at least 100,000 miles was just a expected norm

Can you explain what the premature failure was? This is an early failure.

Click the image to open in full size.
I had wondered if anyone else on this board had ever had to replace an engine in a '04 and up F150.


When the 5.4L started running rough with the engine lamp on I took it to my mechanic to replace the plugs. I figured at 102k that it was about time. It took quite a while to get the plugs changed [those familiar with the problem know why]. But afterwards, it still ran very rough. A compression check confirmed that the number one cylinder was “dead.”


A knowledgeable friend convinced me that we could change the engine and save a few thousand. Several times along the way I wondered about the sagacity of that decision. But now the new engine is in, and while it is slow-going [sometimes it is just too cold to work, especially after a long day] I revert to a philosophy of “one bolt at a time.”


What I found when I took off the valve cover was a spring and rocker laying out of place. What caused it to fail? I don't know. It wasn't from lack of oil change maintenance or abuse. When the spring failed the valve fell down and was struck by the piston.


I have learned a lot along the way. If anyone is faced with a similar dilemma and would like an opinion about whether to do the work themselves or have someone do it for them, please feel free to contact me.

Well, i was the orginal creator of this thread and I decided to ditch the truck. Dodge gave me a fair price on it and I bought a RAM 1500. I guess I'll get flogged out of the forum, but I can't buy another Ford.

Bought a new 2000 F150 Lariat - burned to the ground because of cruise control issue.
Bought a new 2004 F150 Lariat - Replaced transmission VCT knocking like crazy and then had main bearing issues. (only 78,000 miles)

I decided on dodge because 1. They have made mad improvements on the look of thier truck and 2. LIFETIME dirvetrain warrenty. All I want is to buy a nice truck and keep it. I don't want it to die after 5 years and I don't want to trade it in for a new model. At least last 150,000.

I know there are plenty of Ford trucks that last and are good trucks, but that wasn't my experience. I guess I'll go find a Dodge forum.

they will run fine without a converter they are for emmisions only but you will need your o2 sensors to run but if your truck is newer than 96 it will throw a code and you wont be able to get inspected

I'm doing a mild write up in the off topic section it explains most of it! Whole truck will cost under 10k! Look it up called 5.4 3 valve to stoker!

I just replaced my engine with a Reman. 5.4L from LKQ. Cost me $3400 including tax, shipping and them taking my core. Just Google LKQ for their contact info. It will run you another $2000 or more to have it installed...depending on what other parts you will need...belts, hoses, water pump, coils, etc...
