5 L engine knocking
 

My 2012 Ford F150 with only 17,000 km on it, has engine knocking. I Took it to the dealer today and they said the number three cylinder is where the noise is coming from. They said they have to wait too hear back from ford Canada before they can do anything. Has anyone else had this problem with such low mileage?I'm wondering what kind of engine work this might entail?????

One other member here was reporting similar. Username snopro31 I t think. Haven't heard an update from him lately. Pretty sure he is getting a new motor or rebuild, but may be wrong

5.0 engine knocking 2011 f-150
 

This forum helped me tremendously. I recently purchased a 2011 F-150 w 5.0 w 200 miles on clocks. (left over brand new in May 2013) engine was knocking at 1200 miles and got worse w 7K miles 10 visits to dealership got no results til I switched to another dealership and they found crank and other internal parts out of tolerances and swapped motor w a new engine all under warranty. All quite and smooth now but shattered my confidence in ford.

Crankshafts, rod and main bearing journals or pistons go this route if improperly fitted, not properly lubricated when first started up. It happens so quick even if everything is size wize correct but centered wrong. It may be that the block itself is formed wrong from the European mfg. of the block or overheated during the welding of the cylinder walls. A whole bunch of things can happen to create a bad outcome. I believe Ford Engineers will Look at a few of these malf motors. If U make 100,000 of these motors and 99.999% are good U still got a Pick up full bad. My bet is faulty pistons on a few motors. A test of the motor oil is the quickest way to show the immediate direction of it. If U have metal paricles or other in larger than normal amounts it will show u. UR not being dumb to pull a small amount of used oil into a test jar. These are available at parts stores. Have the lab do an independent test for U. U don't go around waving it, U save it. But U shouldn't keep using a noisy auto.

Eng knocking 5.0 2011 F-150 follow up
 

FYI ...after numerous visits and finally went to another dearlership in Phoenix AZ about my eng knocking they found noise from bottom end. crank shaft end play was out of tolerance,( .013 spec is .011) oil pressure was 4 psi below min, (11psi vs spec is 15psi. found cam caps scorn and metal shavings in pan (after recent oil change from other dearlership) rod bearings showed signs of wear . (these are just some of the main things they checked that I am copying from my service invoice)...

Sorry for your truck engine issues. I have a 5.0 in my 2012 with 17,000 miles and have not noticed any engine knocking, only a slight ticking.

Sounds like U need Ford to nu engine U. It's hard for those things to happen to an engine properly assembled new.

Knock
 

Mine was knocking from the left bank looking from the front of the truck..11,000 miles, no towing, no crazy mods.....didn't start until after the first factory oil change at 7,500 miles. Now...it sits in the dealer waiting for a new engine.

low end knock
 

I reported a low end knock at 1200 miles. My brand new 2014 STX,5.0L!! Dealer inspected filter and crank end-play. Apparently the noise went away after the left belt was removed?? Said all was normal. Then Ford engineer had tech check other new vehicles on the lot and knock was present in them also!! So he stopped all work and advised me this knock is"NORMAL"?? This is a knock,knock noise best heard just off idle around 700 rpm. I have heard it in other new trucks on the lot also? Makes me sick! I believe they will give me a power train ESP warranty. But I have doubts as to the durability/longevity of this motor. Good idea,if I don't trade it, I will send oil sample to lab. at next oil change. Thank-You

for member..too manyhobbies..My 2011 F-150 original motor that had the knocking was replaced at 7K miles with a new motor.my new 5.0 motor now has 26,000 miles and no knocking and is smooth and quiet. push for a new motor and good luck..

Just an FYI but when talking about left/right on a vehicle it is done with the person sitting in the driver seat looking forward just as one would when driving.

.

Can anyone run a OASIS on my vin# 1FTFX1EF9EFA84798? I want to find out if I have a ESP Power-train Warranty.

Yes you do.

Thank-You for doing that.I'm Still uncomfortable with the knock,knock noise from the bottom end that is "Normal"! With my luck it will break after the 60 months.

I wouldn't call it normal. Mine don't knock, if it did someone would be putting a new engine in it.

.

Pop the belt off to take out the chance it is a driven noise ( water pump ) etc. ask the dealer to do it.

Took to dealer at 1200 miles.Dealer removed belts and checked crank end play. Tech told me knock gone with belt off? Said they checked 7 other 5.0 engines and heard knock in all? I heard it in two others. Ford engineer stopped any repairs and said it was NORMAL operation.
Very distinct knock and best heard just above idle,700 rpm, in gear. Or driving slowly/backing.

Are you by any chance in Canada or anywhere other than the U.S. ?
.

California,Why? Whats interesting is the fact I can hear this knock in other new trucks also?

So you are in another country, LOL seriously though if the noise goes away with the belt off then it's an engine accessory making the noise. Could be normal.

Mine is quiet as can be.


EDIT: Probably a smog pump for California emissions and why I don't hear it, I'm not in Cali.
.

Knock
 

Yes, this is a indeed a different country.I'm lucky to live only 35 miles from Reno,NV. All cars/trucks out here are 50 state cars. And all I've seen have Cal. emissions.Even cars/trucks sold in Nevada.Do you have 49 state back there? I thought Ford only made 50 State cars? Anyway, no air pump. Left belt drives Alternator,water pump. Right belt drives A/C.Maybe I will pull the belts and check the driven accessories myself,as Papa Tiger has suggested. 2 yrs. ago there was a TSB 11-7-1 for a similar knock, due to a/c mounting. But does not apply as Rt belt tensioner and mounting has been changed on newer models. I expect a TSB on this if you can keep an eye out for me? Disappointed that Ford engineer stopped the tech. when knock was verified in other trucks on the lot. It doesn't sound right for a new motor.Some people might not hear if listening to radio or have a/c fan on. Thank-You for your help

Here is the outcome. 11,300 miles.

2014 knocker
 

Well, This is what I am worried about!!! Towed my little 3,000 lbs trailer last week and noticed knock was considerably worse! I have 3,200 miles on motor now. This knock cannot be "NORMAL". I can either wait until 17,000 miles or trade it in on something else.
Did you notice a knock for very long? Did you wait until it got really bad? or did it happen fast? Quiet now/ You must feel great!

knock
 

I received my oil analysis kit from Blackstone laboratory. I will have 5k on engine soon and will send them a sample. Will see if bearing material is "NORMAL". If it is, then knock must be external i.e.. water pump or torque converter.

Any updates?

What u hear is spark knock from the lean condition of these engines. Try using premium fuel and it will go away

Try using premium fuel in the summer months. I bet it goes away

red knocker!
 

I would be very surprised if this was a spark knock or ping! Knock, knock noise in time with engine rpm.Best heard just off idle under load,like driving up a hill or grade. I now believe it is worse with when engine is at operating temp.
I need to get gas today! 90 miles to empty.So I will fill with high test and see.I live at 5,000ft. What is neat about this truck- it gets about the same MPG as the Ranger I traded. But I only have to go to the gas station 1/2 as often with the 36 gallon tank.
Almost have 5,000 miles and will take to dealer for the works and Blackstone oil test! like Papa said, if it's crank or rod, it will show up in the sample. From the sound of it metal concentration should be way out of spec's.
I got a BacFlip. Not as convenient as my old RollnLock,but a-lot cheaper.

The old Ranger never knocked!

Blackstone
 

Oil analysis @ 5k shows no signs of engine wear. So I guess this bottom end, deep engine knock, at low rpm"s is external and normal for this engine.Thats what I was told by Ford Tech-line. I will test oil again @ 10k also.

Does it sound like mine at 24k miles

Yes sir. Mine got a new engine after sounding like that

I finally took a video of mine. Late model 2011 (9/2011 build date) with 25,000 miles that knocks as the engine is warming up. It's quiet at cold start and it pretty much disappears when the engine is at operating temp. But this is what it sounds like idling while it's warming up. I think the cold temps we are having makes it more pronounced. As stated in numerous threads, it's loudest on the passenger side. The truck runs great and hardly uses any oil. My drive train warranty is up 10/2016...not sure what to do honestly.

If it goes away when it's warmed up, it's not likely to be bearings. If it's just a while it's cold thing, it'll most likely be piston slap (piston hitting the side of the cylinder) - that generally goes away as the motor warms up and the piston expands.
If you have a drivetrain warranty, take it in and get it fixed. It won't get better by itself, but it probably will get worse.
Google "piston slap" - should give you more info

Thanks for the reply. I'm somewhat familiar with piston slap as my previous 2003 5.4 2V truck had that. But I understood it to be very common with that engine. My buddy's '98 expedition had piston slap and sounded pretty bad, but is still going strong at 180,000 miles.

Is piston slap common on these new 5.0 engines? I did not believe it was. Other members have reported an oblong #4 cylinder in a bad batch of blocks. If this truly is piston slap, I can most likely live with it. The risk of having a new shortblock installed may not be worth it in my opinion.

I could always take it in to get my concern documented and see what Ford has to say I suppose.

Engine Oil Engine Knock
 

Apart from miss fitting pistons and crankshaft end play issues...Use ONLY full Synthetic 5W-30 oil in these 5.0 V8 motors. I use Mobil 1...But Castrol is also good. Change every 7500 miles. You gotta keep all those internal chains well lubed. The factory recommends 5W-20 but that is because it gets very slightly better gas mileage with the thinner oil. Better to keep the engine well protected, the new 5.0 V8 has an oil cooler, it is there for reason, heat dissipation, the 5W-30 oil protects the internals better.

2014 Engine Failure
 

I have brand new 2014 truck with 2700 miles on it. The engine is the 5.0 model.

Noticed the engine seemed to be losing power, i.e. took more throttle input to get the truck to respond.

Headed to work one morning, check engine light came on, engine coughed and shut down.

Had vehicle towed to Ford dealer.

Inspection of the engine showed a major failure on the right bank head. Cam bearings wiped and secondary timing chain snapped.

Waiting on a new crate motor now.

Mechanic told me that he is seeing a lot of head failures, mainly pushrod guides worn out. He seems to think it poor quality in the manufacturing process associated with the heads.

I have a 2012 with same issue. I will try another dealership I guess. So annoying that I have to search for a fix myself. This is my 3rd F150 and never had a issue with any of the others but they also didn't have a 5.0 L

5.0L engine TICK
 

I just bought my 2014 left over FX4 with the 5.0L and I have only had it less than a week with only 600 miles on it and it's ticking. I thought I had moved away from engine problems when I traded my 07 with the 5.4... WTF???? How can an engine with only 600 miles on it go bad? I am bringing it in today to find out what is what with this "TICK. :censored: fustrated

This is a little video of my Ticking sound.

Check out this other thread
 

Hi
You are not alone my friend. Check out this thread on here https://www.f150forum.com/f38/5-0-en...6/#post4297760

I believe what you have is just noisy injectors. Mine has same thing. They won't fix it. I did however get a new long block due to a knocking. The first week or so it was very quiet but the ticking isd back as loud as ever. No knock tho!!

rlorion, yours sounds like fuel injectors ticking, which is normal. Can you give us an update? Just a tip, change the oil early while the engine is young, like 1k-2k miles, and 3k miles after that. There is a lot of excess fuel until the ECM adjusts, which winds up in the oil and reduces the protection of the already thin 20 weight oil.

video starts off making the tick/clack whatever you want to call it. It cuts out for about 30-45 seconds then kicks back in at about 1:28 or so

I don't think that ticky is anything other than timing and injectors etc. I have a 2012 and it is noisier than your (with a new long block!). I do hear a faint knocking. How many miles?

Just hit 45xxx

I'm currently waiting on my new long block!

@regor64 you still have this truck? Did anything ever become of the sound? Also was it kind of a thumping/knocking sound?

She now has over 70k on her and the knock is still there! Knock most noticeable at low rpm, driving slow or/ and underlay. First noticed at 600 miles backing my trailer.

I don't suppose you did a more recent UOA?
