The Volkswagen 5 Cylinder is an Anomoly

Here’s a look inside a Volkswagen 5 Cylinder engine and how it works!
The Volkswagen EA855 uses a cast iron block, aluminum upper oil pan and aluminum head with a plastic valve cover. Being an inline 5 cylinder means the construction is similar to a 4 cylinder with a very unique crankshaft timing arrangement. This allows the pistons to be 72 degrees apart for an even distribution of power over the crankshaft's rotation and gives it a unique exhaust note.
The engine in this video had about 155,000km and came out of a 2008 VW Rabbit with a failed 6 speed automatic transmission. While these engines aren't known to have major issues, the PCV system is one weak spot which may dictate complete valve cover replacement. The placement of the intake and exhaust bolts under their respective manifolds and the timing chain at the rear of the engine bring question to the design of this engine for serviceability.

I’m at 190k miles on mine.. just replaced valve gasket, map sensor, spark plugs and coil over packs. Also put on new brakes. She’s running pretty strong still.

[@fisshuman]

Probably why they make it complicated and hard to work because they know this engine would rarely see a wrench. So they give the customer 3 times or maybe more labor cost to fix it. If it's ford or just normal asian car, yeah they easy to work on but that also mean you'll have to work on it at least 3 or 4 times in the lifespan. 😂

[@Delight.AutoCRAFT]

This engine is so clean I'd like to believe you're rebuilding these engines or selling them as parts. These generation of cars makes it hard to be an all round mechanic because of specialty tools. I'm a mechanic and I find it frustrating...

I don't understand why 5 cylinder engines are not more popular. When done correctly they are as smooth as a V6, easier to package due to being narrower and cheaper to make due to only needing one cylinder head and one set of camshafts.

[@EdgarsLS]

V6's have a lot more parts, manufacturers like that because it drives the service costs up, and that's more profit for them.

[@basskot2638]

I have learned a LOT from you, now I actually work on my car myself, I can't believe how much money I've wasted on dealerships. Thank you

[@speedkar99]

I'm glad you appreciate my videos

[@johannjohann6523]

Having a trusted and honest mechanic that actually knows what they are doing is indeed a hard find. I started working on cars and learning about them like you after spending way too much money for a poor service. I also (even though I'm an accountant by trade) have even worked in the auto parts stores. And I can tell you, throughout the car industry the "unspoken" creed is to charge customers for something they do not need. Replacing an already fine part to add to the bill. But also what working at the auto parts store taught me was which brands to buy for specific parts. As it is rare every brand makes every part they sell well and consistent throughout the brand. And then there are the brands that have narrow and focused business focusing on specific parts. Like best bearings are made by FAG (I know, don't laugh). But FAG does not make complete wheel hubs. For Hubs and brakes Centric is a really good focused brand on those parts. But the very best brake pads are probably Akibono. Yep after the Sumo wrestler. lol. So even when working on your car it's good to do a little research. But you are correct about working on your own vehicle, because you can trust yourself. If you do proper maintenance your car will not break down. Driving your car till it breaks is just plain dumb, but happens because not every can afford proper maintenance. But those are your cheap cars. And why I like to buy used premium cars because they are always serviced and cared for so much better than "average" cars. And I don't see a new car worth its price today anywhere. Possibly the new Ford Maverick. Possibly. You are on the right track my friend, and never be afraid of 12V electricity and with a little information you can work on that as well (making sure to have the needed tools). Just remember car companies overly engineer electrical systems in cars to make it difficult to do yourself. And "simplifying" an electrical system is always possible, just think in terms of a "complete circuit" and you should be okay. In other words, running the electrical for the wipers through the cars stereo is pretty dumb. Stereo breaks and you lose the wipers. So to go around it is to have the wipers on their own complete circuit or loop. Anyway take care, and by the way using 100% synthetic motor oil like Amsoil (instead of "full synthetic" which is a blend of 10-40% synthetic with mineral oil) is one of the best things you can do for your car. It seems more expensive until you realize you can go 3x longer between oil changes safely with 100% synthetic. Peace.

[@johannjohann6523]

one more thing to add because "it should not happen but does" is your O2 sensors. They do not have anything to do with air/fuel mixture unless one goes bad. Then the ECM is programmed to screw up the air fuel mixture to run bad if one of the O2 sensors go out in an attempt to force you to go and get them replaced. The o2 sensors are there on the exhaust simply to stop you from removing the catalytic converter. This is naturally on newer models starting around 2012 forward. Just an FYI because this is the EPA being sneaky. Oh yeah, the addition of an oil catch can is also a great benefit for your engine. And only a "nominal" impact on the environment because of the filters on them today. This is a necessity if you happen to have a "direct injection" engine which so many of the newer engines are today. But they do not add the oil catch can. What, you want the motor to last forever or something? lol. This stops any carbon buildup in the valves and even cylinders from happening. Also, adding a low temp thermostat is also a good idea. Something around 160-170 degress. Thermostat temps have been rising because it is believed a hotter engine "pollutes" less. Uh, no not really, as internal temps in combustion chamber are the same. It is just best for your engine and all the plastic components on them these days to have a low temp thermostat. NASCAR uses a 160 degree thermostat. If it is good enough for NASCAR I figure it is good enough for me. lol

[@HowToMod32]

That is a forged crankshaft you have there! You can sell that for a few hundred dollars. Only 06-07 models had a chance of having one. It was like a lottery.

There is a hole for that last hex on the intake manifold. I made my own tool with a long 1/4” extension with a homemade hex loctited into a socket to reach that bolt. Also the socket is loctite to the extension. Reaches the bolt just fine.

[@unassailable6138]

Yesterday I was looking for a mechanical review on a Jetta 2.5 5 cyl on your channel because it seems like a nice engine, but didnt find it. Glad I found a breakdown.

[@wandameadows5736]

It's the most reliable gas engine VW made during that era & they stopped making them like fools. I wouldn't buy one of there direct injection 4 cylinder with turbo engines. BTW you don't need a new valve cover to change the PVC diaphragm on these engines. There's a cap you can pop off but its plastic so use plastic & not metal to pry it off. The PVC Diaphragm is $10 while the valve cover is $100+. If you've come across one thats well maintained its worth buying. It's also important to know what transmission it's paired with. If its an AISIN transmission, which is Toyota, it's even better. VW makes DSG transmission that isn't bad but it's very expensive if it breaks. I've got a 2012 Jetta 2.5L with almost 200K and it runs great, 25 28 mpg & the issues i've had have been minor. The AC compressor does have a solenoid that cost about $25-$30 that goes out & its easy to get to & held in with a clap ring. I buy all my parts off Amazon.

[@speedkar99]

I heard it's common for the valve cover to break when changing the PCV. The transmission that came with this one was toast. I should make a teardown video someday ...

[@speedkar99]

Well I'm glad you found it!!

Lol what type of car guy doesn't like a 5 cylinder? Whether it's from Volvo or from the VW/Audi group they are special...... They sound so good, and have very smooth power delivery. Tuned they are very visceral........ Did I mention they sound good besides they're great reliability? You've never heard a boosted 07k, group B quattro or a IMSA GTO?

Try a Honda K series ?

[@Flies2FLL]

It isn't true what you said about always having a piston on the power stroke. The typical power stroke is NOT 180 degrees; It starts when the spark plug fires and ends when the exhaust valve opens. Typically, sparks fire just before top dead center, and typically the exhaust valve opens about 120 degrees after top dead center, so figure on 125 degrees +/- a few of power stroke. Since on this engine during the first rotation of the 720 degrees for all cylinders to fire, you have three cylinders fire for 375 degrees of power stroke. But the second rotation only has two cylinders fire, for a total of 250 degrees of power stroke. Thus, there is about 95 degrees of dead zone on the second rotation. You are right about these things sounding cool! But the best was the Volkswagen V5 engine sold in Europe, these sounded amazing! Great video!

[@speedkar99]

125*? That seems like alot of power will go out the exhaust!

[@Flies2FLL]

@@speedkar99 That is why turbo's work so well. Also, beyond this point, the primary force of the piston is not contributing to rotation of the crankshaft; Instead, it is simply pushing down on the bearings as the piston approaches bottom dead center. For proper exhaust scavenging, the exhaust needs to open early as well.

[@buffdad5487]

Idk why but when I was removing intake manifold their access ports where matching with bolts on the bottom when I was doing thermostat 🤷‍♂️

[@wandameadows5736]

You don't need a new valve cover to replace the PVC Diaphragm. You can see the cap pops off & you can replace the diaphragm & spring for $10. Just make sure you don't use metal to pry open that pvc cap. I use those plastic trim tools.

[@speedkar99]

But don't they break when you try prying them off?

[@Tony-375]

This is true but it’s a gamble especially since the last year of 2.5L was manufactured in 2014 (them being atleast 9 years old to 17 years old). Most people replace the entire valve cover as others who have tried to replace the pcv diaphragm don’t have a large success rate (atleast in the VW 2.5l Facebook group).

[@josephsmith6032]

You can actually replace just the diaphragm, it comes with a spring and new cover. If you can find a parts guy that is any good dorman make one. I got mine from fibi a division of Bilstein. Not very expensive.

You're lucky enough. This engine has a forged crankshaft. What year of manufacture is this engine? Are there any numbers on the engine or crankshaft?

[@DonnaChassis]

Question. What's a 'hydro formed cam shaft?'

[@speedkar99]

Hydroforming is a manufacturing technique. They place a tube into mold and use water pressure to force it to confirm to that shape.

[@tonyincs]

I have always felt (since living in Germany years ago) that the VW/Audi/Porsche engineers designed the vehicles with the mentality that if any part went bad, you just need to replace the component as a whole. And they definitely did not care about the aftermarket back then. Maybe it was an economic thing..creating jobs/income for anybody who wanted to hold on to their old car?

[@Drmcclung]

I've always felt that German engineers design engines with the mentality that if any one part goes bad, replace the entire vehicle. Total deletion of the engine oil dipstick among other totally asinine and hostile to the owner design decisions confirm this.

[@speedkar99]

Yes. It's part of planned obsolescence.

[@markchidester6239]

I'm waiting for these engineers to mount the oil cooler to the top of the exhaust manifold

[@speedkar99]

Anything is possible.

[@chuckycheese84]

Don't give them the idea. Although i'm sure that a engineer on drugs will come up with that idea somewhere

[@mr.knight1359]

im not an engineer but i cant think of any reason why in lots of german engines they put the timing part on the side of flywheel. so if something goes wrong with timing ( which lots of them are famous for that ) its would be such a pain to fix a simple timing issue

[@speedkar99]

Agreed. Seems Akward from a servicing perspective. For longitudinal mount it makes more of the weight towards the back of the car but that doesn't make sense in transverse mount....🤔

[@earlscheib7754]

This was a great engine in the Passat if well maintained, if neglected the timing chains fail and the car becomes a money pit.

[@speedkar99]

Always wondered about the chains...being at the rear of the engine it much people mention failures

[@kilovwdude6457]

These engines are related to the audi 2.5 and take boost remarkably well you can throw a turbo kit on it and then make around 300hp reliably

[@michaelstrongbow2336]

Really, only 148hp? Not comparing apples to oranges but the Volvo N/A I5 2.4 liter makes 176hp. If this is the block for the RS3 then the head and turbo make drastic hp gains, interesting. Not completely sold on doing a timing job and having to separate the trans from the engine. But those RS3s are fast! IMO

[@speedkar99]

Sorry I got the number mixed up it's 170HP which is more comparable but still paltry by today's standards given 4 bangers are making 200+

[@triplebarreldarrel]

Dude that engine produces 170 or 177 hp in the 2008 rabbit can't remember if 177 was torque or hp but the other is 170 so either way somehow they got an extra 22 to 29 hp after 2007 same engine also produces 150ish in the 2011 jetta.. why I don't know 😕

[@michaelstrongbow2336]

@@speedkar99 170 HP sounds more like it, thnx for the reply. Honda made some i5s I guess, can you keep an eye out for one of them for a teardown plse? I can only imagine how much HP and torque a direct injected, turbo'd, and V-tech'd i5 would produce? lol

[@MiguelGarcia-vj7oo]

​@@michaelstrongbow2336 this engine was handicapped by the factory to not compete with TSI sales. That's why these barely made power from factory. Integrated Engineering makes a nice stage 2 N/A kits that pushes these into 225 hp. They fully built one to 280hp. The sound clips are a eargasm I suggest you research. These can take about 12 bars of boost reliably making 400 hp max with stock internals . With internal modded, they can make as much power as an RS3 due to parts interchangeability. 2. These engines are part of the 07k family of engines including the Audis. These are just watered down. Iroz motorsports in Las Vegas uses the VW iron block for their 1300hp RS3. Again The parts are interchangeable. 2. The 07k engine was designed by Ulrich , who is the head Audi engine engineer. He based it from the Audi IMSA GTO race car motor. This is the same guy you created the Diesels for their dominating Le mans program. Lastly if you see some approachable builds I suggest looking up that Dude from Donut media and 07k swapped golf or ECS Tuning project 944 Safari car.

[@marcarteaga1474]

Has anyone had any issues with the timing chain?

[@Flies2FLL]

By the way, these are a member of the VAG EA888 engine family. The EA888 is an evolved version of the EA827 four cylinder unit that was first produced in 1974 for the Audi 80 and Volkswagen Golf. The four cylinder eventually grew to 2.0 liters, but due to the extremely compact design, it could go no larger. Thus, VAG simply added a cylinder. They didn't stop there though; They took two EA827 designs and using CAD/CAM they produced the Audi V8. Then they took two cylinders off of that to produce the Audi 90 degree V6. Then they built a V10 out of the 5 cylinder that found its way into several Audi's and the Lamborghini Gallardo. [Interesting side note: All this had been planned in the early 1970's. Ferdinand Piech even went so far as to suggest to the leadership of Porsche that this V10 design be utilized in the Porsche 928...] Diesel versions and an inline 6 for Volvo were built, and even diesel V10's and a V12! I suspect they got their money's worth out of the original EA827 design budget....

[@speedkar99]

Thanks for the brief background

[@workingmanaudio2754]

I read that these were from the gallardo v10 and have nothing in common with the 4 cylinder engines.

[@Flies2FLL]

@@workingmanaudio2754 No, these are a development of the four cylinder, as was the V10.

[@workingmanaudio2754]

@@Flies2FLL Wow. The v10 and 07k don’t seem similar to the 4 cylinders. Interesting.

[@Flies2FLL]

@@workingmanaudio2754 It may seem odd to say the engine in an old diesel VW Rabbit and the V10 in the Gallardo are related but they are indeed the same engine family. This is an evolved design rather than a new one, and nearly all variants from four to twelve cylinders can be built on the same machinery. The biggest give away is that they all have the exact same bore spacing, 88 mm. The EA827 block is tiny. In fact, it is starting to be common for hobbyists and racers to install the cylinder head from a Suzuki Hayabusa motorcycle on the VW block and then make stupid power. Some welding and drilling is involved, but it is nearly a perfect fit. Because this block is so small is why it not only fit in the early Golf/Rabbit, but why they had to add a fifth cylinder to it in order to get more than 2.0 liters displacement. Once they went down that road, it was easy to think of other variants.
