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

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.

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?

Dude, come back mate. What are you doing? Amazing content in this channel, great set up, high quality sound + camara. Just come back!

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

Yeah, I have a 2015 LE 1.8T 5 speed tuned Unitronic Stage 1+ with 103k miles. I've had a couple water pumps which was no big deal, an issue with the Turbo's waste gate because I wasn't lubing the linkage pivot point. I've completely replaced the break system because I'm in the NE and really beat on it. Other than that, I think I can get another 150k miles out of it. I'll drive it until the engine catastrophically fails.

@mynameisnotcory It's always a gamble with vehicles. I thought for a moment I was starting to burn oil, but I've been checking it a little more than usual now, and I don't seem to have an issue. I was running mobile 1 0w-40 for about 60k miles. I switched to a 5w-30 after. I run an engine flush every oil change because I run the oil for 10k miles. I've sent oil samples in for analysis, and I've been told it still looks good even at 10k. I also run crc gdi valve and Turbo cleaner before every third oil change. Not sure if the extra maintenance is necessary, but it makes me feel good.

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.

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 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.

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.

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?

Is that red silicone under the head gasket, is it a genuine VW factory silicone? Please give me a response.

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

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?

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.

@MarkMethods

3 жыл бұрын

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.

If that's the case there were warranty exstentions on injectors you might be able to get your losses covered

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.

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.

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.

@MarkMethods

3 жыл бұрын

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?

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.

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.

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.
