Can I swap engines from a 2002 to a 2005 Ford F150 XLT Triton 8?

Asked by Nov 19, 2015 at 03:36 PM about the 2005 Ford F-150 XLT 4WD

Question type: Maintenance & Repair

I bought the 2005 Ford F150 6 months ago and it's had one problem after
another with the Triton V8 XLT ever since. After $4,000 in engine work, and
after the last oil change, the oil pressure tanked and the engine seized up. The
dealership it was towed to says the engine is shot and has to be replaced.
I also have a 2002 F150 with the Triton V8 XLT that I put a new Jasper in 3 yrs
ago - the original engine kept blowing out spark plugs.
My question is if I can put the 2002 engine in the 2005?

It will probably drop right in, but before you spend money and effort, many States have emissions laws that a replacement engine must be the same year or newer than the recipient. yep, those Triton heads only had 4 turns of threads and on aluminum heads on top of that. They blew out like bullets. . It was ridiculous

Having the same problem with my 2 valve 5.4 in my excursion. 6 spark plug hole rethread. And now one of those rethread is stripped. Looking to replace with another engine that will bolt on without much modification that is not blowing plugs. Any suggestions

Engines changed to 3 valve in 2004. Until 2008, I believe. I wouldn't buy an F150 from those years. Get one prior or after. Trying to "rig" an engine that does not belong to the year is a recipe for trouble.

Now they used the 5.4 in econoline vans till present day. I have heard tale that up till 2008 (2009 went flex fuel) that they should swap. Has anyone heard different?

I have a 5.4 Triton engine in my 2002 ford king rance and treated it like a baby, but still, only with 70,000 on it ,the timing chain ( I hear it has 3 timing chains, 2 in rear, one in front. Its junk. Ford should come up and have some BALLS to recall all those trucks that have the original owner,, replace with some other v8 engine. I heard about after 4 years they stopped that engine. Not really sure

We have had a 1999 Ford F150 that we bought brand new. Very little money put into it. This past June the engine finally croaked. We put in a Jasper Engine and it ran fine. 3 weeks ago a 83 y/o driving in a residential subdivision and she took out my husband's 16ft trailer his riding mower & yes his truck.....All totaled Thank God my husband did not get hurt. I want to buy my truck back from salvage yard. Anyone know if I will be able to sell the Jasper engine?!? Also can I put that engine in a 2006 Ford F150?!? I have a friend who is interested in buying it. I would appreciate any and all feedback, Thanks

The only difference in the 5.4 engine is the one prior to 2004 is a 2 valve engine and is a much much better engine than the 5.4 3 valve triton they came out with in 2004. You can buy a cam phaser lock out kit for the 5.4 3 valve and lock the cam phasers and it will be just like th old 5.4. I have a 2007 with the 3 valve and I put the cam phaser lock out kit in it and no problems so far. But you will have to have a tune or your ecm if you put the cam phaser lock out kit in. I also have a 2003 5.4 2 valve in a 2003 f150 and it has 285,000 miles on it and I have had it 10 years. Best truck I ever owned, not one bolt turned on the motor so far besides tune ups and regular maintenance on it.

I have a 99 f150 4x4 with a 5.4 can I put that motor in 2002 4door f150 with a 5.4 4x4?

I have an '02 with 303,243 miles and just now my #5 cylinder has lower compression than needed. I'm not complaining - that engine has been a Man. It's in a F-250 4x4 that works Hard about 4 days Every day of the week pulling 5 to 12 thousand pounds of trailer and farm equipment. Reading these comments, I think I'll just rebuild my existing engine rather than upgrading.


My head gasket blew in my 2003 4.6 v8 f150 with the titan engine. Can i swap it with a 2001 engine that is still a 4.6 v8 f150 engine?

Seems like everyone keeps asking questions, but not many real answers. Oh well, here goes... I have THREE, Ford F series trucks... 2010 F-150 with Triton 4.6l, 2 valve (yes, TWO valve in a 2010); and a 2001 F-450 with Triton 6.8l, v10, 2 valve; and a 1993 F-350 super duty with 7.3l idi diesel (non-turbo...the million-mile-factory- bullet-proof school bus engine) So...the F450 blew a plug, stripped threads, was my first time encounter. I hopped in the F-150 to go hit the "ST"ealership up for advice....about half mile from the house, THAT truck blew a plug! I limped it back home and hopped in the F350 and MADE IT to the dealership. There I learned theres only 4 threads (1/4 inch of aluminum) holding the plugs in, and that Ford techs use the "Cal Van" thread kits to reem, tap and install new threaded insert. Cal Van kits are about 200 bucks, versus the 6 to 15 dollar kits sold at chain auto parts stores. The 450 is my weld rig, so needed it on the road ASAP, so bought a cheap kit and tried it. Actually, in tried it on the 150 first...reamed the hole, tapped new threads, inserted the insert, fire up the truck and had a miss in the rumble! Swapped out trucks, did all same crap to the 450, and ended up with same result...a miss in one cylinder! So, I'm not a complete moron, I know I did it correctly....with is the problem!?!? I'm about to order the CalVan kit, and try it all again, but cant understand why both trucks ended up with a miss. ....and after reading the thousands of other people's stories, want to start a class action suit against what "USE" to be my favorite automaker! WTH Ford!?!?!
