Lol, another idiot who thinks the 5.0 is still the same as the old 302 engine.

Idk if you've been reading up on recent issues with the 5.0 but many owners (myself included) had to have the engine blocks on our 5.0's replaced because of piston slap due to cracked or distorted cylinder walls. People say it's an issue with just the 2011-2012 trucks but it has happened on later build 2013's such as mine. It's not the "tried and true" V8 everyone thinks it is. I suggest you go read up and get edumacated before making those claims.

The shudder is caused by possibly warped brake rotors.

The issue with the Vacum pump can manifest itself in different ways,
one is audible: A really loud groan or a grinding noise when hitting the breaks, both those noises originate in the front driver side of the truck. That mean your pump is about to go, get it looked at ASAP.

The most dangerous manifestation is that you loose power brakes altogether. Your breaks won't fail per say, but you will have to push that pedal with all of your might to stop the truck, and even then it will take about twice a much distance to stop it. Often resulting in hitting something.

You could have just said that the brake issue isn't related to the reliability of the engine itself but instead you went the EB fanboy route. Speaking of irrelevant. So if that's what we're doing now ill play:

Enjoy your gasoline turbo and the much higher long term maintenance costs associated with it. Speaking of "slow" that's exactly what you'll be in 10+ years, and we're talking the REAL kind of slow, not your delusional "slow" label that you place on the 5.0 to justify your engine choice to yourself. When those POS turbos start leaking and losing pressure you'll have to shell out all that coin and/or do all that work just to keep it from being a slow, scrap worthy joke. LOL. Sssucker!

As far as techknowledgy goes, your correct not the same. Still the same balanced block. Aluminum vs cast, pushrod vs dohc, 4v vs 2v etc... Yes the Coyote is a much more advanced motor, with independent valve timing, roller rockers, hydraulic valve control yada yada, but it was still based off an old motor, not some hybrid engineered recently. And the piston slap? What 1 out of 1000 owners might get that? A forum with how many members, 20k? And there might be 100 instances. All I'm saying is much more R&D went into the Coyote from a "tried and true" version than did the egoboost, and the dependability shows.

That sounds more like warped rotors....get them checked, and the dealer can run your VIN to see if you need a new vacuum pump or not. Probably not as no recall is in place yet.

I am curious why the engine effects the brakes?

Why wouldn't Ford use the same braking system in all of their trucks?

Not 100% sure but I would assume the V8 engine itself pulls enough vacuum for the brakes, while the V6 doesn't. Or maybe the 5.0 has a mechanical pump instead of electric

Earlier posts mentioned a load noise coming from behind the drivers side headlight and having a very stiff brake pedal for a minute or two after starting the truck. I think the problems were worse for trucks based where there was a lot of snow and road salt in the winter.

Here is the previous thread I was thinking of.

It is not based off an old motor. Try and find a part on the new 5.0 that will fit the old 5.0. It was a brand new engine from the ground up. It shared some components with the modular line but overall it was brand new. The Ecoboost is based on the 3.5L Duratec V6 which has been around for a decade now.


And FYI the knocking issue is bigger than you think. My engine replacement that was done in April was the 14th short block job that that tech had done so far this year.


So if 1 out of 1000 owners have issues with the 5.0, does that mean 1000 out of 1000 owners with an Ecoboost have issues? No. Your argument is invalid and heavily biased. And THAT shows.

So out of the quarter million f150's with 5.0's sold in the last 4 years, hes done 14 this year? Staggering amount really. And its not just the vacuum pump issue, how many people have had egoboost engines grenade also? How many threads have started with "ecoboost regrets" and "Why I wish I would have bought a 5.0" Never seen a "Wish I would have bought an ecoboost..." You can't argue that the boost doesn't have more issues than 5.0. And your saying those toybo's will bolt straight up to the Duratec garbage motor, since they are practially the same? That thing will probably hold up as well as the ecoboost's do. Not heavily biased, just manage a shop. I'd buy an ecoboost over a GM product any day, but never a V6 over a V8.
