why would valve self destruct? car wizard 2.0t video

[AudiTLC]

just saw this and i know it's not b8, but it's the same 2.0t motor
curious your thoughts on this?
https://www.youtube.com/watch?v=4wVUq9P3ouE

he doesn't have a good opinion of the 2.0t, and i'm at a loss how the valve could self destruct without the timing going bad.

[Theiceman]

that was a TLDR video .. 20 minutes ??

so was it just a burned valve ?? not uncommon if you have a injector running lean or a bad HPFP . not the end of the world and he should have fixed it .

he gave her 2500 bucks, he will fix it and flip it for 15k im sure.

[AudiTLC]

a short version:

He says "there is an entire chunk missing from the valve"
https://youtu.be/4wVUq9P3ouE?t=393

He lists his diagnosis and price logic here
https://youtu.be/4wVUq9P3ouE?t=712

He lists a cylinder head at $1200, new timing chain kit, book time=15-16 hrs, misc, intake carbon cleaning possibly
his est. was $4-7k for the repair.
He says he could just replace the broken valve but that was a "band aid" fix and wouldn't be good.

There is something strange about this- It feels like this isn't the catastrophe he makes it out to be.
he did state the customer didn't want to spend over $500 for any repair so...
However, just wanted to gauge opinion here.

Take Car Wizard with a grain of salt..

I've seen exactly one 2.0T in 15 years with a burnt valve(Excluding tuned cars)

....But..... I've seen about 3 burnt valves over all Euro models in the same time period...and I've wrenched 1000's and 1000's of German/euro cars.

Dude is capitalizing on his profession, and that's fine. Good for him, but just be aware of his videos...they aren't malicious, he's just making some extra money on the side..

He seems like a decent mechanic that specializes in nothing specific, like most shops.

The 2.0T is far more likely to have oil pressure/oil consumption/timing chain failures @ 100,000 miles than anything else...that specific failure is an oddball.

Yeah there’s a car wizard video where he covers which Audi’s models to avoid, and it’s clear he doesn't know much about Audi’s.

[AudiTLC]

Do you agree with his assesment it's a $4-7k repair?
I feel like, yes, it's arguably true but to actually do a good repair and not "while you're in there" added costs... I doubt he even checked the timing chain stretch for example.

850k subs. he's making a decent chunk every month off of yt and it seems a lot of actual business from it too.
He comes across as a very honest mechanic and I can't disagree with his logic but... it feels like there is a level of repair that is both good, and far less expensive
or at least more due diligence before recommending all this work.

thanks for the professional perspective!

(and IMHO if he was doing that great, he wouldn't need to supplement with YouTube money..but maybe he's just that ambitious. He seems like a decent mechanic that specializes in nothing specific, like most shops.)

you're probably right. being a more broad strokes kind of mechanic. I guess the lesson with Audis is you need a brand specific mechanic that really knows them.
From watching the channel, I know he doesn't work on BMW's anymore and passes them to a BMW specialist (all through Hoovie's Garage).
I've watched that bmw mechanic's channel, and I get the impression that BMW's are total garbage. LOL I guess looking at a Audi shop, casual viewers would feel the same.

yeah that's the plan it sounds like

Naptown Tuner would absolutely resurrect that Q5 and probably for a lot less money. He makes house calls for the right amount.

I won't pull the head on a lateish model 2.0T for less than 20hours...That's $3g's for most shops that know what they're doing and that'll dive into an Audi. If you're pulling the head, you're doing chains and a water pump(because it's right there) Easily 4'g after parts....add in a valve job. If I do the valves myself, that's another 1/2 day (4 hours and you're getting all 16) and the sodium filled valves aren't cheap. My machine shop guy charges $1000 for a 16 valve head job, and I have to mark that up.

Let's just say it's 7g's on the high end...What's a new Q5 2.0t run? $50 to 60g's from my brief google search(MSRP is a suggestion, and "market valve" increase are still prevalent in metro areas)

I'm on the side of "cheaper to keep her" unless the client has more money than time.

I wouldn't let that guy change my oil. Seriously. He may have knowledge of the platform, but he's a hack.

or from the that shop owners point of view " tell her how expensive it is so i can get it cheap and turn a massive profit "

similar thing happened on my sons B7. snapped timing chain , said it was not worth spending the money to fix as it would be in the thousands, more than the car is worth, but they would help him out and give him 500 bucks for the car.

I called CAA had the car towed home, and fixed it for said 500 bucks. car is still running great 5 years later. i get they have to sink time and money into it .. but to tell a college kid its not worth fixing his car and here is 500 bucks to walk away i find disgusting.

the comments in that post talk about him being a hero .. im not so sure...

[Theiceman]

i have see a few of his videos and i generally agree with this , he is very knowledgeable about the theory of operation and typical failures as he has obviously seen a lot. I also see he has many of the tech bad habits and short cuts. i wouldn't go so far to say he's a hack and he is here helping people. I would just say i would rather do the work myself.

it should also be noted techs take short cuts based on what they have seen in the past to save them time. As warranty pays so little, the auto manufacturers have really created this issue, doesnt mean a short cut is bad, but where do you draw the line.

I very very briefly worked for a piece of shit owner, and that was his MO. Total a car with a quote for the soul purpose of repairing and reselling.

Well, that's my definition of a hack. I used to repair cars for a living many years ago and we had plenty of hacks in our dealership. Everyone wants to make money by beating the book time on a job, but I've always believed in doing the job by the book, even when it takes more time to do it that way. I've watched enough of Naptown's videos to know that he's a total hack, even though he's unquestionably knowledgeable about the B8 platform and more specifically the EA888 engines. The shit I've seen him do is simply mind boggling.

That's such a scumbag move....but I know it happens and happens a lot. On the flip side, I've seen customers basically abandon their cars at a shop because they couldn't afford the repairs. The shop owner can eventually assume ownership of the car, repair it out of his pocket, and then sell it for a good profit. If the original repair estimate was fair and accurate, then you really can't blame the shop owner when someone completely walks away from their car.

[Crucible35]

Similar to this, my head unit is currently being rebuilt due to a broken exhaust valve in cylinder 2.
Should be getting it back "if all goes well" tomorrow. They'll be doing the timing chain but not replacing the pistons/rings.
Shop has no idea how this could have happened, but said it could have been a stuck open injector.
Car has 228,000 kms on.

Wow....that's certainly a compression problem right there....lol

exactly , I have seen this also.

[Greggybase]

I burned/chipped a valve in April of ‘23. Replaced the head with a used head that had been reconditioned. All in with “while you’re in there” stuff it was $7500 at a very reputable shop. After 12,000 miles I chipped another valve this week. FML.

[A4 Centaur]

^That friggen sucks! Hope you can get it fixed inexpensively

[Theiceman]

is the car an oil burner ?.

Just replaced a burned valve also and it was decently $$$ and we did the work ourself.

Love that quirky man! Plus he is a Christian and I dig that. /religion plug

[Theiceman]

we are starting to see a correlation between oil burners and burnt valves...nothing concrete though.. might make sense if we are not getting a clean burn..

Carbon likely builds up on the valve seat in the cylinder head and on the valve. This inhibits heat transfer between the valve and the cylinder head which is essential for cooling the valve.

that would certainly make sense..
