2017 Ecoboost 56k miles ticking

powerboatr · Feb 20, 2019

i am not sure what you are hearing.
it sounds exactly like mine does at idle, maybe a bit more pronounced because the mic is real close.
but mine sounds like a machine with lots of moving parts, no odd harmonics or tick tock or odd balance
once mine is past its first warm up routine after start, 60 seconds, then its all quiet and rhythmic
i have had lots of diesels and this sounds nothing like those ticks or ping.
just my 2 cents

Here is the video of the Sound.

This does not sound normal to me. Thoughts?

Oil was changed in December, Ford Oil and Filter, he is not sure of weight.

No, this doesn't sound ANYTHING like my 2016. Way more like a "clattering". Almost like a timing issue.

Jeff, I am pretty sure this was after warmup.

I am getting confirmation.

Confirmed. That was with the Motor warm.

Sounds exactly like mine even after warm up. I've put 21,000 on it since I purchased (had 29K) and it sounded like this from then. No issues with performance or gas mileage.

Do let us know if he finds out something is wrong with it.

I've got another 6 years and 75K miles on the extended warranty to remedy it.

I've been getting it serviced at Ford dealerships and none of them have said anything about it.

Ford released a TSB for clanking and ticking noises on 3.5 ecoboost engines due to cracked piston skirts. If it’s getting worse over time this may be something to look into.

Camphasers failures are also documented like many of fords other overhead cam engines (4.6, 5.4, 3.7). Just throwing out two items that are known noise causers on this engine.

Based on what JPExpedition said, I found it. Yikes!

SSM 47394 - 2013-2018 F-150, 2015-2018 Transit/Expedition, 2015-2017 Navigator - 3.5L EcoBoost - Engine Tick Type Noise From Cylinder Block

Some 2013-2018 F-150, 2015-2018 Transit/Expedition, and 2015-2017 Navigator vehicles equipped with a 3.5L EcoBoost engine with greater than 20,000 miles may exhibit a tick type noise from the cylinder block area. This noise may be caused by a cracked piston skirt. The noise can be isolated to a cylinder using a stethoscope or other suitable listening device. Canceling the affected cylinder will reduce or eliminate the noise. If the noise is isolated to a specific cylinder, it is recommended to replace the short block. If the noise cannot be isolated using the methods described, refer to the Workshop Manual (WSM) for diagnosis. A cracked piston skirt does not result in metal contamination of the engine or any related cylinder head damage. Prior approval for short block replacement is not required under new vehicle limited warranty coverage.

This thread (scroll down to it) has video of a 2012 F-150 piston skirt failure and rebuild video. The 1st is how it sounds. Just like a Diesel, much worse than mine or the one posted on this thread.
