what it is, what it costs.

2017–2020 Ford 3.5L EcoBoost (Gen 2) F-150 🔴 Shop job, needs a hoist, a press or a machine shop

Shops quote $3,500–$5,000 for this one, and the quote usually isn't the ripoff, the job really is that big. Here's what's actually failing, what the correct repair involves, and the honest part: this is not a job I do in a driveway.

What's actually failing.

The second-generation 3.5 EcoBoost (2017–2020) got revised internals, but the cam phaser weakness followed it. The phasers still wear under boost and heat, still lose their grip on cam timing at cold start, and still produce the trademark rattle in the first seconds of a cold morning. The PCM logs the same family of codes. P0011 through P0022, and pulls timing to protect the engine, which you feel as hesitation right when the turbos come on.

Gen 2 trucks add a second problem that loves the GTA's driving pattern: carbon buildup. Port injection on this generation helps, but trucks that live on short trips, school runs, site visits, stop-and-go on the 401, never get hot enough for long enough, and carbon accumulates on the intake valves anyway. The symptom is a surge or stumble at steady throttle and an idle that's never quite settled.

The bundle logic is simple: the intake comes off for the phaser job anyway, which is exactly the access needed to walnut-blast the intake valves, and the coils and plugs are right there too.

The symptoms.

If your Ford is doing any of these, this is the likely cause:

  • Rattle for the first seconds of a cold start
  • Check engine light with codes in the P0011–P0022 range
  • Hesitation or stumble when the turbos spool
  • Surging at steady cruise speed
  • Rough or hunting idle
  • Carbon-fouled running on a truck that mostly does short trips

What this job typically costs.

$3,500–$5,000
what dealers typically quote for this repair
That number is usually honest, not a scam, this is a genuinely big repair. What's worth $100–$250 flat is confirming it's the right repair before you pay for it.

The honest answer first

I won't pretend I do this one in a driveway.

Cam Phasers, Timing Chains & Carbon Cleaning Bundle is on my published list of jobs I turn down. It needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. That list is public on my trust page. I'd rather lose the job than learn it on your engine, and you should be suspicious of anyone who says yes to this over the phone.

So here's what I can genuinely do for you, holding a $3,500–$5,000 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.

Option 1

Second opinion, at your car

$100–$250 flat at your location

Before you spend $3,500–$5,000, have someone independent confirm that's actually what's wrong. This is a diagnosis, not the repair, no hoist, no lift, nothing comes apart. I scan it, test it, look at it with you, and tell you straight whether their diagnosis holds up. If it does, I say so and you go pay them with confidence.

Option 2

Buying something else instead?

$149–$399 flat pre-purchase inspection

At $3,500–$5,000 on a car that might be worth not much more, plenty of people replace instead of repair, that's a completely reasonable call. If that's where you're heading, get the next car measured before you hand over money: 150 published points, at the seller's location, written report the same day.

Tell me what you've been quoted and what the car is doing. $100–$250 flat, at your location, and you get a straight answer either way.

A straight answer, not a sales call, including "their quote is fair, go pay it". Or call/text 647-450-0406.

Jobs on this car that ARE mine:

What the correct repair involves.

Not so you can do it yourself, so you can tell whether the shop quoting you understands the job:

  • All cam phasers replaced with current updated parts
  • New timing chains, guides and tensioners
  • Walnut blasting of the intake valves and ports while the intake is off
  • Spark plugs and coil inspection/replacement while access is open
  • New gaskets and seals throughout, fresh oil and filter
  • Scan and boosted road test to confirm codes and drivability

That's the job. It's why this one belongs on a hoist instead of in a driveway, and it's why $3,500–$5,000 usually isn't a ripoff, it's a big repair honestly priced. What's worth checking is whether that's really what your car needs.

What it takes to do this one properly.

Plain version: Cam Phasers, Timing Chains & Carbon Cleaning Bundle needs equipment a driveway doesn't have, a hoist to get under it properly, a press or a machine shop for the parts that come out, and a controlled space for an engine or gearbox that's in pieces for days. I work out of driveways with hand tools. That's not false modesty, it's the published limit of what I take on, and it's listed on my trust page alongside the warranty.

What that means for you: this page is here to tell you what's failing and what it should cost, so you walk into a shop knowing the job instead of nodding at a number. And if you want that number checked before you pay it, that part I can do, $100–$250 flat, at your location.

Why not to wait.

Phaser wear accelerates once the rattle starts, and the PCM's protective timing pull means you're paying for power you're not getting every day. Carbon, meanwhile, only stacks deeper. Separately they're nuisances; together they end in a jumped chain on an interference engine or valves so coked the truck misfires. Fixed as a bundle now, it's one day and done.

Frequently asked questions.

Didn't Ford fix the phaser problem on Gen 2 engines?

They revised parts, but 2017–2020 trucks still develop the cold-start rattle, there's an active pattern of it and updated service parts exist for a reason. If your Gen 2 rattles cold and shows cam timing codes, it's the same failure with the same proper fix.

My truck mostly does short city trips. Does that matter?

It's exactly the pattern that builds carbon fastest, the engine rarely runs long and hot enough to keep the intake valves clean. If that's your truck's life, walnut blasting during the phaser job is the highest-value add-on there is: the access is already paid for.

Will you do this job at my house?

No. Cam Phasers, Timing Chains & Carbon Cleaning Bundle is on my published list of jobs I turn down, it needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. I'd rather lose the job than learn it on your engine.

So what can you actually do for me?

Two things, and both are real. A second-opinion diagnostic at your car, $100–$250 flat, at your location, so somebody independent confirms that's actually what's wrong before you commit to a $3,500–$5,000 repair. And if you're weighing replacing the car instead of fixing it, a pre-purchase inspection on the replacement, $149–$399 flat, at the seller's location.

Why publish a page about a repair you don't do?

Because the useful part isn't the wrench. It's knowing what's actually failing, what the correct repair involves, and that shops quote $3,500–$5,000 for it, so you walk in knowing the job instead of nodding at a number. If you want that number checked before you pay it, that part I can do.
