yes they did but not enough to worry about. i am a returning customer 3 times now. I wasnt going to go look at new trucks when I got mine. The manager himself called me and told me to come up there.

we have bought 8 trucks from them in the last 6 years or so.

 

Good deal then. They have to move inventory.

 

I am looking at a 2010 Platinum with the 5.4 liter engine in it. Only has 47k miles on it!!

How have these engines held up? anything i need to look for?

 

The 3 valve 5.4L engine is a good engine. Many have seen 200K miles without major issues. By 2010 all the problems are worked out. Keep up with normal maintenance, use the correct viscosity oil (5w20) with OEM oil filters, and don't abuse them are key to longevity. The transmissions had some shifting issues (harsh shifts) in '09 and '10, but a good programmer such as SCTX4 with good custom programs can deal with that nicely.

 

Hi there my 2010 5.4 F150 is in the dealership right now because while I was driving seven days ago suddenly the engine started to shudder or vibrate I thought at first it was just an ignition or electrical issue so I brought it the following day to the dealership where I bought it , they did a diagnostic first which I was charge for $99.00 and they said ignition is fine and they recommended to do a compression for $199.00 on top of the diagnostic charge , result one hole has only 30 psi and the other two holes has only 89 psi I can't believe it until now I babied my truck and only has 73000 km and drive it like a wedding limousine I'm so disappointed with this 2010 5.4 F150 but I really like ford and I don't know why I've never owned any other car aside than ford but this was my first truck , now to get my truck back on the road the ford dealership gave me to quotes first $7900.00 before taxes for a used engine or $9200.00 for a new engine and because of my disappointment with this series of year model I can say it's a big lemon truck , I hope sharing my experience will not happen to other ford truck enthusiast thank you and good luck to you .

 

Sorry to hear that, turtles. Had a coworker with an '09 5.4L engine that failed at 98,000 miles. Compression was fine, but it was making noise, and the bearings were scored. He was fortunate to have a 100,000 mile warranty that picked up the tab.

 

I just went from a F250 6.0 to a 2009 F150 5.4 with 80K on the clock.

I have heard nothing but great things about the 5.4. Mine is a Larit package fully loaded. All maint done the the dealer with a clean carfax. Everything but 4x4 I should say. Looks like everyone thinks this engine is a good one.

 

They are generally good.

My 2010 has become somewhat of a problem child lately. Since about 30k one (or both) of the VCT solenoids sticks and the engine loses oil pressure to the top of the engine and idles like it is missing about half the cylinders. Completely random and now that it is out of warranty there is ZERO chance of getting it fixed.

My exhaust manifolds are also warped. To the point of getting exhaust fumes any time I idle. Which sucks because that's my office for most of the year and I do a lot of work out of my truck. It's actually to the point now where I can't drive it any more and I'm going to have to switch trucks.

It is supposed to get fixed, but they say they need it for 2 weeks and refuse to send it out to someone who can get it done more timely....

Just rolled 69k today.
Disappointing.

 

Thinking about a 4x4 2010 F250 with the 5.4 and AT. Has 100k on it.

I guess the spark plug issue was solved by 2010. I want a motor with a low-probability of things like failed exhaust manifolds,lifters, and such.

I am thinking the V10 is more reliable than the 5.4.

I probably only need a truck which is highly reliable for about 8 years and 50k...at that point, anything I buy will be a rusty ball of worthlessness.

Thoughts?

If you are looking for a vehicle with a low probability of problems with failed exhaust manifolds and lifters, then don’t look at 5.4’s or v10’s. Both are notorious for both.

spark plugs won’t be an issue on either though. That was sorted out somewhere around 2008.

just being honest.

 

You won’t have lifters to deal with, but if the engine is the one that was installed at the factory, it definitely won’t have the updated guts that a remanned engine should have.

I would pass in that scenario.

Of course, you may have a reman in the budget and like the truck. Your call.

 

Feels like the 5.4 isn't for me. Thanks, guys.

I guess Ford didn't make the 300-6 and a cast-iron 4-speed in 2010, did they?

Nostalgia always favors the positive. Those engines were simple, but they didn’t hold up as well as lots of modern engines that are known for going 300K+ miles without much drama. The 3v 5.4L isn’t that, but there are exceptions like everything else.

 

5.4 3v’s are well known for lifter problems. Roller followers to be more correct, but the rollers can wear out and go slack. Usually they make a lot of noise when they do this, but it often goes unnoticed because the cracked exhaust manifolds make a similar sound and drown out the noise the lifters are making.

left long enough it will spit out one of the followers. Usually one of the intakes and usually on cylinder #7. When you lose one of the two intake followers you end up with a weird misfire that comes and goes depending on throttle pressure and can be a nightmare to track down unless you recognize what has happened by the unconventional symptoms.

they aren’t all bad. I’ve put a lot of miles on 5.4’s. My 06 never had an internal problem and the exhaust manifolds never gave any trouble. Bought it with 104k and sold it with 218k. My 2014 was good except the exhaust manifolds. Had to replace both of them. One around 80k and the other around 150k. Bought it at 75k and Sold it at 175k because it was blowing some smoke at startup.

they aren’t all bad, but there is enough bad ones to take note.

 

I am almost 68. I have been driving, and caring for vehicles, since I was 16. I have generally run trucks in the 90k to 200k mile interval.

I have never replaced: a manifold or manifold gasket, any valve-related parts, any timing-related parts, rings, bearings, oil pumps. I have driven both American and Japanese vehicles.

It just feels like all of the sudden, it is really hard to find a truck which won't break my streak.
