What you NEED to know about Ford EcoBoost Engines by Dustin Golley of DG's ProTech

[Music] hey there welcome to protec today we're going to check out a video on the pros and cons of the notorious EcoBoost engine submitted to us by Dustin golly let's take a look everybody its Dustin here from Dedes Pro Tech and Westwall want to get another episode of DG's TV off to you today we are talking about the notorious 3.5 liter EcoBoost or broto it's trials and tribulations and kind of what makes it so notorious [Music] we had a customer come in for a very common complaint on their 3.5 EcoBoost this engine is in an f-150 and it's in the Ford Edge before Explorer and a lot of other for applications now the reason it is is because really it's a great engine we have excellent economy excellent power and if the vehicle is taken care of really they're a long lasting engine power / displacement there's not many engines that come this close so let's talk first about what makes them as great as they are without being biased and then we'll talk about really what makes them so notorious and what makes them problematic because there's a whole other side of that coin that we should also talk about so this customer came in with the timing chain out of phase code so it's telling me the correlation between your intake and exhaust camshaft remember I should go back one step this is a dual overhead cam v6 with variable cam timing on both independent camshafts it's also turbocharged with a twin turbo setup it's also high-pressure direct-injection gasoline so a lot of things going on this engine which is what makes it so powerful for such a small-block common concerns are this is a high performance motor this is you know getting into what was racecar technology only a few short years ago it needs to be maintained meticulously in my professional opinion this engine should have synthetic oil only and it should have it synthetic oil changes done not at the extreme interval of fifteen thousand kilometers like the oil change minder on the dash will allow you to do if those things are taken care of in the maintenance is impeccable of these trucks lasts a long time and we don't see some of the common failures like turbocharger failures turbocharger bearing failures and timing chain stretch problems as they're commonly concerned this customer came in of course with the timing chain stretch problem and what it really is is actually where between the links of the timing chain so we can picture a whole bunch of links like this and as they where do the lack of maintenance they they wear into each other and a little bit of where in each timing chain physically allows the chain to be longer than it should be the timing chain tensioner set up in the system cannot take up all of that slack and eventually the timing the timing gears on the camshaft side are allowed to float further than they should actually be able to do now the computer will pick up on this because it's very advanced and it will actually start to phase one or more of the phasers to try and bring your base timing closer to zero once it goes outside a calibrated limit it'll set the check engine light throw the truck in the lock power mode and you'll be into a shop like ours for a pair now if the customer chooses to still ignore further because it can be a cost repair it's not as scary should think that it can be eventually actually seen as the truck will actually jump time and in a case like the other EcoBoost in our shop today it jumped time to the point where Pistons and valves have collided because this is an interference engine and now that customer needs major major engine repair so a couple base things you can see in this engine of course we are twin independent variable cam timing which means we have a solenoid that runs this intake ice only that runs this exhaust and again over here for this intake and this exhaust so they can be variably advanced and on the fly we have a port and I'll show you the parts over here in a second for a high pressure direct injection basically this is your injection pump like you'd find on a diesel but in gasoline world it's a little lower pressure probe maximum to 2200 psi it runs high pressure lines down here to your high pressure rails there again gasoline that have direct injectors in the cylinder by using direct injection we can be extremely efficient in the use of our fuel and the delivery of our fuel to get excellent atomization now some customers will argue with me in this video and say you know the EcoBoost that I've driven or from my friends that have had one have said it's not that efficient of an engine it really doesn't get that much better fuel matters than their five year f-150 which is the competition motor within the same brand and I hear you I have driven an EcoBoost over a long period of time if you use an EcoBoost and you stay out of the actual boost it can be more eco however if you drive one of these trucks and you enjoy driving the vehicle you won't want to drive out of the boost you'll want to be into the boost because they're a really fun engine to drive of course as we up boost in an engine we have to up fuel to have the correct air fuel ratio and that's where those trucks really don't get a whole then our fuel mileage than their v8 competitors you know maybe slightly better but it's when they really shine with her into the boost and that's why they're towing numbers are in excess of 11 12 almost 13,000 pounds towing capacity and personally they'll do it so here we are over the bench guys with the part from this EcoBoost that we were just talking about a second ago now to give you an idea if you go back in a couple of our videos we did a very similar video on the five-point for the Detroit f-150 you're gonna see a lot of the same layout and will kind of make some references together as we go so this is your basic timing chain layout that's been recently removed from the truck so you have your timing chain guides you have your timing chain tensioner you have your where your crank crank gear would be running your timing chain up and over bank one camshaft down around an idler and up over bank two camshaft and then back to our crankshaft now on the five four we run two chains to do the same thing on this because you're a run chain we have to run this either in the middle downside that I personally and professionally have with this system is really we do see timing chain wear and what happens is because this tensioner will plunge out as far as it can keeping tension on the the chain as it can this chain ends up slapping a lot because there's no tension over here in a better setup and actually in the new twenty eight Tina from 50 EcoBoost they've addressed this by putting a second tensioner here to take up any extra slop also the chains a little lighter than I'd like to see for this engine design but it is what it had it is and with proper Maiden's we don't see problems with this so over here another component that's important and it's nice to see is we have our old timing chain compared directly alongside a brand new Ford timing chain they are perfectly lined up and though it doesn't look like much you have about a link link and a half longer in the old chain and it's not that this chain has another link that's your physical wear that this tensioner over here I was just talking about is trying to take up that much slop is all it takes for these to get out of phase set that correlation code with timing and cause issues so the repair and it's actually been made at TS be a technical service bulletins by Ford is to disassemble and replace the chain my opinion again we should go in and verify that everything else is not worn excessively before we just simply put a chain in it a lot of times you'll find your tensioner has gone out past the maximum number of clicks and therefore it cannot tension and it's probably been bouncing off the bottom that piston and the plunger I'd highly recommend a new timing chain tensioner retail on this from Ford as of today is $65 it's not it would be silly not to replace this component while we're in there we don't see a gasket a phenolic gasket like we did in the 5.4 there we also don't see a plastic housing this is steel there is no warpage here we very rarely lose any leakage here like we did see in the 5.4 there so this is updates that Ford has obviously made in their systems a couple other neat components will show you just because we're disassembled this is your high-pressure injection pump it is mechanical it means it runs off its own separate cam lobe driven off the actual intake camshaft there's a square lobe there that's just sitting here going pulse pulse pulse pulse pulse so low pressure comes in you know 50 psi give or take and high-pressure exits based on demand from the regulator to ramp anywhere from 500 to up to about a maximum 2200 psi now 2200 psi doesn't sound like a whole lot when we're running gasoline systems upwards of 25,000 psi but it's gasoline so volatile 2000 psi gasoline pressure really is all you need to do extreme advancements in horsepower and get that good direct injection atomization really that's all I've got guys the last thing I guess we should talk to you back over here in the truck is the turbochargers we talked about the fact that the EcoBoost can get great efficiency provided you stay out of the boost they are an internally gated turbochargers the wastegate is built into the housing of the turbocharger max boost under stock application you're going to see the 13 to 15 psi which is a lot for a little truck like that that said a lot of people when they start to try and get that economy they stay out of the boost driving it accordingly the problem is then the wastegate never opens because it never hits max boost that same customer then tows a trailer you'll move the RV once in the summer the way stake they hit max boost the waste gate opens and because it has an open cycle a bunch it'll be seized in the housing and then we have stuck open wastegate issues so the turbocharger is you see here located right on the end of the exhaust manifold and there's a left and right this is just easier one to see has a wastegate diaphragm that will open that mechanical waste gate which is internal the turbocharger housing around that 15 psi of boost it starts opening it at 5 psi max opening at 15 psi and if you've been driving it for efficiency and it hasn't moved for a while and then it goes to full cycle it may stick there and then one turbocharger may be working correctly the other not and then you'll get a weird like I call it the the whining dog rrrr noise because one waste gate is trying to cycle when it's stuck that is our number one cause with turbocharger fitters customer will say you know I had an EcoBoost it was good but I had all these turbocharger and timing chain concerns really if we just cycle those turbochargers once in a while by driving it the way you want to drive in the first place we don't see a lot of turbocharger feathers and full circle now we'll talk about the maintenance again if you keep good quality oils and filters in these trucks at the right time periods not necessarily that extended twelve to fifteen thousand mileage I tell guys five thousand KN regular oil 8,000 km synthetic kidneys treat him like a diesel because really they are almost like a little small diesel and this EcoBoost will last you a long long time and you won't have to come see us for a pair like this that said we'll wrap this up with if you do have a concern like this with your EcoBoost come see the experts here we're using four ids top align scan tools to be able to diagnose these and get them repaired at a cost that's going to be as low as it possibly can for you the end customer that's it for us today at DG's protec here guys follow us on facebook watch these videos tag your friends so they know all the good things that we've got going on here and we'll see you next time [Music]
