- This is the teardown of my failed EA888 1.8T Generation 3 revised design for the 2015 Golf to find the route cause of failure at 87K miles. In the video I mentioned 79K which is incorrect, slip of the mind.

Wow amazing. Stuff like this is the best of automotive youtube. I have a 1.8T ea888 gen 3 in my passat. So far no issues at all at 40k miles. It's mesmerizing to see the engine my car has torn apart. It looks very hard to do and hundreds of bolts and screws involved. Is everything an engine out procedure on this engine?
This engine did not die from ring failure .the marks on the bore were from water sitting there for a while, more likely a gasket failed causing coolant to go into the cylinder, probably could have been saved if caught earlier. Bearings looking mint
nice of you to present this, but you are an exception. this new generation is actually quite reliable.
This wasn't meant to suggest this was an unreliable motor with my singular example, I was highlighting how VW didn't offer assistance at such a low mileage failure on a CPO since it is an exception. This is why I will not be purchasing a VW in the future, previously I've owned a Golf TDI, GTI, and lastly this TSI.
Four years ago had a misfire while driving. thought i could make it home from work. it stopped turning over when i tried to leave the job. battery was good. after taking off the head, the intake valve was broken into three pieces and the valve seat crushed into the head. this was due to the valve spring braking allowing the valve to fall into the cylinder. the valve gouged the cylinder wall and cracked the number four piston. this is a rare failure but found a few forums of VW owners who also experienced this issue on the 1.8 tsi gen 3 as well.
I beat the hell out of my 2015 1.8t. Mustve been an anomaly type failure. Ive heard if these engines were assembled in mexico opposed to germany they have a lot higher chance of going to 200k miles or more which sounds like the opposite of how it should be
@@MrKawasaki911 @110k now, still running great but drinks oil
Dude, come back mate. What are you doing? Amazing content in this channel, great set up, high quality sound + camara. Just come back!
I just replaced the engine in my 2014 passat 1.8t. Two valves were burnt, and I found a very low mileage for cheaper than the cost to do the valves. Not sure how it happened, but I understand these engines to be very good. Just some bad eggs in the batch I guess.
My 1.8 tsi just lost compression in two cylinders at 182k had absolutely no issues with this car but a o2 sensor. Very sad. Is it worth a rebuild or just throw another engine in it with less then 100k
I believe you had over fueling or a head gasket failure letting coolant into the 1 cylinder. Rings stick all the time from carbon and soot. They usually won't give you the issues you found.
Is that red silicone under the head gasket, is it a genuine VW factory silicone? Please give me a response.
Did you take the side bolts on the side of the block off for the main caps?
Looking at the block I think that's exactly what I missed. /facepalm
So this had to be a non standard failure, definitely something up with that rust and weathering inside that cylinder. No way that can happen normally. There is almost zero chance of this happening without water exposure.
I think the dealer left it with the spark plug out in the rain outside once they confirmed low compression.
@@MarkMethodsyeah but even if they did that they the head gasket wouldn’t have did was it did around that one specific cylinder if it had a good head gasket bud
I have the same engine in my A3 8v1, recently it started smoking and using a lot of oil and fuel, what could be the problem?
So you didn’t have a code after your EPC light was on?
how do you know which generation of the 1.8tsi engine you have? is there a VIN on it?
What can be the issue if I have oil in water cooling circuit and also drop of oil under the turbo.The engine is CJSA 1.8 TFSi 180 hp
These engines are known to have oil leaks. And oil changes intervals are too long. I change it arround 7000-8000 kms instead of the 15 000 suggested by vw. When the oil gets old, it has a tendency to burn easily. I got 161 000 kms and i check oil often. If you dont take care of it, it will break. They’re reliable, but not as solid as 90’s japanese cars.
That's probably where I went wrong, I try to listen to the factory manual but looking at these wimpy oil wipers on the pistons and high consumption of oil; I'm surprised more of these don't fail under VW's recommendations.
@@MarkMethods Thanks for sharing your teardown. Looking at the amount of varnish inside that engine it looks like it has been run for too long (and or hard) between changes.
@@MarkMethods i have a 1.8 tfsi engine from 2009 and the oil was changed every 10k km, never drank any oil, vw is destroying their reputation by saying stuff like changing the oil and 15k kms
@@nicu7437 I’m a VW tech and I can tell you that not all shops are using good quality oil, and that’s half the issue. However, even with better oil I’m still a firm believer in changing the oil way more regularly.
How much is the oil consumption on your engine and what oil you use?
Why would this engine be consuming oil?
My oil has decreased like 3 quarts in 300 miles.
Do you know of any common issues with that??
Everything underneath is bone dry, however I noticed oil around my spark plugs (the white part)
So I assumed valve cover gasket. However no oil is leaking underneath or on top of the engine (that I can see) hoping to figure out why it’s consuming so much oil and hope it’s an easy fix.
That's excessive consumption but it must be going somewhere; there are UV dye kits you can add to the oil to help identify where it's going if it's leaking; if it isn't ending up on the ground it could be getting consumed but at that rate you'd have ruined the catalytic converter pretty quick. How long has this been going on?
@@MarkMethods i just got the car used.
It seems to run fine. No odd noises.
If I did use the dye, where should I look engine wise? Turbo? What are the most common things?
I would look around the timing cover, oil cooler up front, oil pan seal at the bottom, and around the splash shield at the bottom with the UV light to see if anything is glowing to help identify the source.
@@MarkMethods okay thanks!
New piston rings never hurt anybody either. I dont know what kind of records you have for the car but this just sounds like maintenance like regular oil change with OEM oil was neglected by the last owner leading to scoring of the cylinder, piston ring failure, blow by and other issues.
hello! I have a 2010 audi a3 1.8TFSI with CDAA engine. I have the error of excessive oil consumption?
The two things that i know go bad with this engine are the timing chain jumping time and the intake valves carbon build up. Unfortunately you did not seem to even look at those problems. I am sure you did but you neglected to put it in the video. I am sure your diagnosis is correct but i would have liked to have seen the valves and checked the timing of the cams.
Those are both great points I should have gone deeper; timing never skipped (no kiss marks in the cylinders). I will note, those valve were crazy carbon'd up and should be cleaned once every 100k if I was running this engine again. I still have a majority of this engine in my garage, if there's enough interest I can dig into what's left. I started getting nervous due to the 20 minute long video and probably cut too much of my discussion and commentary out.
Hey me and my cousin just swapped in a rebuilt 1.8 for his mk7 golf but it’s been running good for a day or then smoke and die any suggestions?
Sounds like the rebuild might not have been setup correctly, piston rings may not have been seated causing smoking and compression loss or head gasket failure. A lot of things could be wrong in this scenario.
If that's the case there were warranty exstentions on injectors you might be able to get your losses covered
Are you going to modify the block. Like sleeve the block to use standard rings again
This block is toast, swapped another motor in and sold the car off.
Change the oil on time, and you will have no engine failures. I have a passat with the same engine with 174000 miles, and it runs perfec.
ok i am at 10:21 into this video. i see cyl 1 and 2 have a ton of carbon, im guessing detonation/ping/knock, knock sensor cut all boost in a attempt to prevent catastrophic failure, perhaps water passages were plugged around 1 & 2,..now let see what you have to say.....OK NOPE i was wrong lol
Good work!
Thanks!
you didn't happen to record pulling the engine?
Hello there! What is the name of the part removed in the 7:10 minute? Thank's
High pressure fuel pump
Kind of looks like a blown head gasket?
Piston ring failure due to low oil, 10k oil change intervals on motors that consume too much oil is a bad design and bad guidance by VW. Check your oil levels between changes and expect a quart or more to be gone as these go up in miles.
That’s what I was thinkin, head gasket blown and water in the bore caused the damage
What can be the issue if I have oil in water cooling circuit and also drop of oil under the turbo.The engine is CJSA 1.8 TFSi 180 hp
If you had removed the 3 center bearing cap side bolts they would have come out 🤦♂️😆
Guy is kinda a idiot blamed the compression failure on rings when you can clearly see it had a bad headgasket
What do you think about a 2017 tsi s with 58000 miles on it worth 11000$ should I get it ?
For the money I'd be considering a Prius or a 2017+ Camry; if it's a commuter and you want the least amount of maintenance I'd vote Prius. If you end up with a VW, make sure to monitor oil levels and keep them topped off between changes due to consumption.
Get a Mazda bro
At 4:19 I was like...WHAAAT?? I thought the water pump was a belt driven supercharger......then i'm like...ohh waterpump duhh, weird design.
Plastic, plastic and more plastic. Therein lies the problem - bean-counter engineering.
MAn the intake manifolds the worst to get them screw out
The most problem because of failure new days engines it’s Oil (recycled)german car does need more often to maintain then Japanes but also a lot of shops recommend to change oil at 5k miles or 6 months guess what no body won’t do it because factory recommended at 10k or 15kmiles(marketing for less maintenances)for sure every engine will make it 50-60k miles until warranty coverage but later gonna happens something like this.Folks change oil (recycled) often 5k or 6 months
Video started great you were describing what you were doing then ya just went into a montage of removal and 80’s porn music. I don’t know what I’m doing brother lol need the description and any helpful hints along the way
remove the bolts from sides first the try to open it. crankshaft bearing
The piston got hydraulic hit. The 3 ring piston grove is missing metal.
You probably had broken valve spring. You didn’t finish diagnosing the problem.
No marks on the valve train, springs all intact. I couldn't conclusively say whether it was lean state related but definitely piston ring failure.
What's that smell?
I WONDER CAN VAG GROUP DONT RE-ENGINEER THE ENGINES LIKE BEFORE ? All the tsi, tfsi , fsi crap ?
damn my 2.0T FSI is still going strong at 195k miles. Ofcouse I did lots of maintainence
headphone users be warned: there is no one behind you....
Pcv fail
11:16 was that a fart? 🤣🤣
I cannot confirm nor deny.
Rotary engines last longer lol
In this case, yes that's true lol.
I have had car with 1.8 tsi. Never again tsi from VW.
i have 2015 vw passt 1.8 t and i have same problem #1 misfire and only 80 psi at #1 i am going t put used Engine and sale this junk VW car
These engines are straight up trash. Mine did the same at 100k
Bad work!!!!!!!
