these do not have hydraulic lifters, the buckets come in several sizes and are matched for a fixed gap. This is fine for 50-60k miles, then it needs adjustment. To do so, the shop has to remove the head, measure the gap, order specific buckets, remove the camshafts, swap the buckets, put the head back together, check the gap (and prey they got it right...), bolt the engine back together. This costs over $1k to do, takes about 3 days (waiting on parts) during which the shop has a non-driveable car taking up space, so it's rarely done when it's supposed to and the valves and seats get beat to death from the excessive gap, causing compression loss. All because Ford was a cheap c*nt.

In the design phase some boy wonder must have convinced somebody that through a miraculous new process, wear in the camshaft, bucket, valve, and seat would be eliminated. It is sad to see so many of the new engines, with so many wonderfully designed and built aspects, have one or two fatal flaws.

Seriously, I'm with you on that keyless crankshaft - I think they're saving a dollar by eliminating the keying operation - and gaining several dollars by selling those magic washers. That little pep talk at the end reminded me of a painful lesson I learned as young man : I bought a rim from my local salvage yard, and took it to a tire shop to have a tire mounted on it. The tire shop had the foresight to check the rim, instead of just putting the tire on and sending me on my way - and the rim was warped. So I took the rim back to the salvage yard and they gave me another. This time, I mounted the rim on my Jeep and checked it before going to the tire shop with it - and it was also warped! I went back to the salvage yard for another, and asked them if they had a way of checking them. The gentleman said "We sure do - we sell them to someone like you, and if they bring it back, we know it's bad". Ouch! So glad to know you don't do business like that - and I really enjoy the videos!

Wow 2 years since the last 2.0? Feels like 10 months ago. Time sure flies when you work hard! Keep it up.

I in no way feel shorted if your teardown reveals an operable engine. It was an interesting video, Eric.

The key thing is just them saving money by not machining the cranks and the pulleys for a key. I've been a machinist for many years and key ways usually have a .001 tolerance on the width and key and the location is also usually a plus or minus 1 degree tolerance. The current machining rate (my shop) is about $145 an hour so if they can save that for the millions of cranks they produce, that;s a huge amount saved.

@jimmyaber5920

I worked for a car manufacturer as a trainer and field support. When theb keyways went away in the early 90s the info was that tolerance drift and market emissions adaptability were why gears quit being keyed. The cam setup and crank positioning was blueprinted like hotrodders have done for ages. If deck height or cylinder deck to cam centers varied then it was handled. If turbo and non-turbo engines had two ideal cam setups then the robots and the dealer service tools handled it.

Exactly my thoughts after seeing that demonstration at the beginning (and then the lack of obvious damage otherwise later on to offer an alternative cause of loss of compression on 2+3) The only other option I see is incorrect clamping force on the head in those areas with the less tight head bolts (located around the area between 2 and 3), assuming the mating surfaces and gaskets were all in spec.

Unfortunate to see a good $3,000+ used motor go to waste but then again, you could freshen it up with new rings, bearings and polishing and maybe get $4k out of it. Outstanding videos BTW.

I have a Duratech 2.0 in a 2005 Ford Focus and I have 138,000 miles on it. I have changed the valve cover and gasket, plugs, and coils. I noticed, when I was in there, that I will have to change the timing chain in the next 40-50,000 miles and it seems to be a pretty simple job. It uses the same "diamond" washer on the crank so you have to have a tool to keep the crank in the correct position and a bar on the head to keep the cams in place. Other than it being a tight fit, doing it in the car, it is really a simple job. I have no complaints with this engine. It is much better than the new "wet belt" system Ford is using now.

I could care less if the engine being torn down is bad or good. A good engine is better for Eric, so as long as I get to watch a teardown I'm happy.

Love it Eric!!

I love that you commented on the non keyed crank. My opinion…. Anyone who has worked on a fusion, or any other modern car without the use of a two post lift will often pull the crank pulley to make room to pull the engine away from the transmission and out the top. I would assume that that was done on this engine. So, the timing was enough off that the engine ran poorly, or not at all, but not far enough off that pistons dusted the valves. It happens on these engines. I would encourage any backyard mechanic to purchase a book or subscription to a reputable repair site before attacking a project of this scope. Unfortunately, if this is the case, the seller ended up taking the financial hit for a beginners’ mistake.

It makes you feel that you can fix anything yourself, you make it look so easy. I most recently watch your video on the Volvo 70 R. What a SCORE! The reason I am writing you back on this video is once again, you show the carbon buildup in the intake port of a direct injection engine. Why does that happen? Most diesel engines are direct injection and why would the carbon bild up in the intake port so much? What causes it to do that and obviously you don't approve and neither do I. Fortunately I drive an ordinary single cab Isuzu pick up KB250 2016 with the Gen 6, 4J engine in it. It seems that I am lucky enough to have port injection as the injectors are to one side outside the valve cover on the intake manifold side. Best Pick up ever. No fuss, relaible and hard working. If you have done an explanation on one of your videos I missed, please send me the link below. Jan

Wow, great way to check relative compression, take the plugs out, stick the coils back in and spin it see how high they jump! Great!

I like Eric holding the chain saying "Yes Yes" and you can almost hear the dollar signs

In the Mazdaspeed community I've seen a lot of situations when people replaced all timing parts and even rebuilt engines because of accessories side poor maintenance, AC compressor pulleys and so on. It may be one of those cases with this engine as well.

I know these engines need a certain spec of oil to reduce these problems, i am in the uk and have a 2012 focus st having some problems with code for catalyst below efficiency, strangest thing is when i was attempting to change the catalyst and had to abandon doing it and tighten everything back up including the flange clamp on the turbo to exhaust connection the problem stopped!

Say Eric… Anyone ever suggest attatching a piece of 5 or 7 ply plywood to the tops of the stand legs (with appropriate holes cut out) so that your drain pan sits above the legs and not between ‘em. Might make your job a lil easier and keep your floor a lil cleaner.

Hey, it's worth mentioning that from 2017 to 2019 a different block was used in fusion, escape and edge. 2.0 in the ST was always closed deck, while from 2017 in the models mentioned, Ford used open deck design and instead of improving cooling, they caused problems with head gasket failures (mostly between cyl 1 and 2) and mentioned cracking of the block.

Thanks for another great video Eric! Could we get a VW 2.0 CR TDI on the engine stand? Particularly engine code CJAA if you come across one.

These engines tuned with no key can usual withstand up to 500whp before the timing can slip. Those friction washers put in some crazy work. It seems some auto manufacturers believe keyed cranks can lead to being a weak or stress point of failure for the crank there. That's what I've heard but not sure its true for the keyed crank.

I think your motor there has major compression issues..Great vid!

I would like to see you build a working engine with scrap parts 😏

I don't know what it is, but there's something really therapeutic about sitting on your couch and watching somebody else turn wrenches after battling with it yourself all day.

I think you might have my old motor. About a year ago I bought a 14 focus st. Next day started a straight up misfire on cylinder 1. I figured that it was just a dead plug/ignition coil but rather than trying to fix it I brought it back to the Ford dealership and they ended up just replacing the engine. The day I got the car I put fresh oil in it as well as a motorcraft oil filter. I know you said the date code was 2015 but I have to wonder if this was that engine. It's not unheard of for STs to get new motors after a previous owner blew the stock one up with either poor driving or bad tune.

I used to work at a place that rebuilt parts and engines and I can tell you that we got a lot of returns of parts that tested good on the test stands. Maybe incompetence or maybe a little bit of fraud going on? We got a lot of good alternators back as defective. We also bought cores that were almost new and we loved those. Just about all the parts we good and reusable, though we put new brushes and bearings in everything.

That is the cleanest I have ever seen of all the 2l I have worked on omg
