Smart man

Makes me apprehensive to buy a used car in case the owner followed those ridiculous manufacturer oil change intervals. They don’t care about your car as long as it makes it out of the warranty period!😔

The BMW dealer thought I was crazy for not following the 15k mile rule on my 335i. Never would I run a $20k engine that long on oil that costs $60 to change.

@@slscamggood man my 335 just spun a rod bearing 5 thousand kilometres after buying it im assuming since the previous owner did not keep a proper oil change interval on n54 super sad ngl

My Toyota dealer thinks I'm crazy too for changing oil 🛢 at 5k....they recommend 10k but I'm doing every 5k.

This is why I do a fuel system service every 5k along with synthetic oil and 87 octane per owner's manual on my 2021 Hyundai Sonata Limited 1.6 T. Other maintenance items would include tire rotate and balance. 4-wheel alignment every 2 5k oil services.

@@jeffreycheng5984 fuel system service has no impact on direct injection, except maybe keeping combustion chambers cleaner. Valve are not touched by gasoline - extended oil change intervals CAN impact them due to oil vaporization/evaporation.

Why is Toyota the only automaker to use both direct and indirect fuel injection?

@@KM-ol5bs thanks, I didn't know

@@KM-ol5bs Ford uses on the Coyote (5.0)- the port injection is only used under high load, intake ports still get nasty- a 100k Coyote has valves and ports like a 40-50k DI engine. Good Oil is key. Not quick lube/Walmart cheap oil changes!! (Those ever, not just DI). QUALITY synthetic oils changed 5-7k will drastically reduce the garbage in the intake and ports/valve... Drastic as 25-40% improvement... Oil catch cans DO help... Again QUALITY IS KEY... Cheapest on Amazon/eBay is not going to do the trick....

People never learn from begging

I know your pain I spent 8k in repairs in a 2012 VW in 6 month time period. I fix one thing then 2 weeks later there is another problem

some cars suffer less due to effective PCV system. I've heard that N55 BMW engine is ok , while Audi 4.2 S5 V8 (2007-2010) requires regular blasting.

Exactly what I was thinking. I'm not sure if the 2.0 was direct injected in 2012 but that build up is completely likely with DI engines.

@@eppyz even with direct injection, still should not get this bad.

@@ayayoutuber VW took out the dual injection that the euro cars have that pretty much eliminated this problem... but its also part of routine maintenance... so as long as you get the valves cleaned every 60,000 miles is not a big deal. Many earlier direct injection systems did this the newer vw's it's not as bad.

Was about to say the same thing. Oil change intervals and quality of has don’t have anything to do with DI carbon buildup. This would have happened even if the oil was changed every 5k and premium gas was used.

Yuppp its made to last "100k" you have to change it or it will fail

Yup if you are getting Audi or VW get one that was manufactured after 2014. Those have the chain system that last for the life of the car supposedly and it has tension sensors. They were sued over a decade ago for the chains failing way before 100k.

Also oil consumption issues are more likely fixed after 2014

@@au123ful yep. that said, there are other serious design failings that can brick the engine all the way into late teen years, not sure which exactly, but all 888 derived engines are not worth buying used as cars ,unless the price is way below e.g. the current US mkt prices for these Vw and audi cars here in USa.

@nomenclature9607 haha I was about to add in my original comment that with a Camry you can get away with using low grade gas and being stingy on oil but never a turbo VW

@nomenclature9607 Not everyone wants a Toyota Camry and the owner of this vehicle could have avoided the repairs if they followed the manufacturer's maintenance and fuel requirement recommendations.

Since it is direct injected, fuel does not have any effect at the inlet valves. An oil catchcan can reduce the carbon build up

@@Rextraordinaire German engineering is overly complicated and not too robust. I had an 88 300E that cost the price of two Camry's to own and maintain. Maintenance alone was worth the price of a new Camry at the time and you could have bought two, put one up on blocks and ran the first one with little maintenance for the life of a VW.

in europe they have 18000 miles oil intervals and 2 years.

I bought a 2015 escape with the 2.0 turbo changed oil every 5k with supertec full synthetic and every other fluid changed ahead of time and now my son drives it to school. Still runs good at 235,000ish miles.

Well the 1.8 T is still a MPI type of engine that cleans itself from the carbon buildups. Later direct injection engines all suffer the problem of the carbon buildups that are caused by the fact that modern cars all recirculate the exhaust gases this means a modern car runs up to 70% of the air that's used to fill the cylinders has already been used in a previous combustion. In order to increase the filling rate of the cylinder the hot exhaust gases have to be cooled down and this is done in a combined valve cooler device that's connected to the cooling water cycle. However the cooler gas cannot contain the same amount of smut like the hotter gas and so you create the buildups. This is the mother of the problem the cooler you make the gas the better for the efficiency of the motor but the more carbon buildups you have and it seems the engineers of VW have put too much weight on fuel economy and not so much on durability. Others might have made other decisions. Regular oil changes help and there are also some additives available that shall help to clean the system but I don't know how good they are. Luckily my car doesn't have any of these problems since I am running it on LPG and when I am making an oil change after 10,000 miles the oil is still of a dark honey colour instead of the black you get from petrol or even worse diesel engines. However the LPG conversion is not cheap at first place and I don't know if LPG is available in the US here in Europe it is different for country to country.

Several gas and diesel turbos in the family. From an X1 to a Juke to Macan S to mini Duramax Colorado. The gassers get 10 k km (6 k miles) oil changes except the Macan. It has an 8 litre sump. It goes 15 k km 9 k miles). The diesel is 12 k km. Don’t EVER look at a diesel intake manifold. Looks like asphalt. Oh ya only 87 gas is all of them. Including the Moto Guzzi. Don’t bag drive them to red line and they’ll reward you with several hundred thousand miles like ours.

@@habi0187 Here in the US my dad had a farm tractor converted to propane back in the 70's, today it's not cost efficient compared to petrol. It's a popular fuel for home heating in rural areas.

@@londen3547 here in Europe it's different LPG is about 40% cheaper than petrol or diesel so if you drive enough it pays back. Additionally you can avoid many problems with the engines as long as the system is implemented professionally. Unfortunately there are not many shops that can do it really good.

Intake cleaning ought to be routine maintenance item, but the VAG pretends it doesn't exist.

and a common reason timing chain tensioners fail, is lack of oil. People not checking their oil. However in the VW's I think the problem was that it didn't have anything to stop the piston from exiting the housing of the tensioner, so it'd just keep pushing.

@@TougeSolo well we don't know exactly what the problem is with this particular car all I'm saying is that on this era of Volkswagen it was very common have timing chain tensioner failures it was a faulty part and was fixed with a revised part so if the person didn't get the revised part didn't care to get it done or bought the car used in didn't know about this problem then there you go.

he gets paid regardless. it's not like he's doing this for free.

@@sihotechyes but he gets paid based on scale. The longer he takes the less he makes.

EA888 have dual injectors (intake and direct). Deposits shouldnt be a problem.

@@JohnAbrahamsenI’m afraid that’s not true, to my knowledge no EA888 has come with port injection. Mine certainly doesn’t have it as I like to think I’d have noticed when I pulled the intake manifold to deal with a faulty (stuck open) injector.

No offense, but suggesting that oil change intervals make no difference is one of the most ill-informed things I've ever read in a YT comments feed. If that's actually the case, then you should be able to change the oil every 100k miles without consequences (which is clearly a ridiculous statement). Oil change intervals are there for a reason, and these days manufacturers are optimistic (to put it politely). I'd rather change my oil more often than the book says and spend an extra $50-$70 a year on oil and filters than $5k or more on major repairs because the oil gummed up and led to engine damage.

@@TheKnobCalledTone. I was speaking strictly in terms of carbon deposits on the valves, and when I read that paragraph again it’s pretty obvious. Of course oil change interval matters, just not for the reason stated in this video.

ninja clown

That was a good episode. And not only mileage on the oil, but some of these odd new oil specs that can "flat spot" [as in fail to maintain a minimum of 8 psi per 1k rpm]. Who cares what meager fractional fuel economy "gain" is when it makes the engine fail prematurely? I respect design for cold viscosity - they want 0w, then ok. Flow is worth more than pressure at start up. But that is not where an engine lives: 30 [hot] seems to make the most sense, except for the tightest of engines. I will definitely never trust 16 except I need to run in Antarctic or the nether regions of Canada midwinter.

he has 4 yachts, 3 model girlfriends, 2 lambos, 3 houses, etc. Thats why he is chill.

Yes, considering he doesn't know what he's doing and is just winging it without following the factory procedures. Also, disappointed in how it looks like he plans to repair the head -- by just plopping in new valves. This car should have a rebuilt head, and new tensioners, chains, cam bridge, possible turbo, etc.. This is a hack repair. Not impressed.

​@johns6331 The question is the customer willing to pay for the job??

That's funny he probably has a dollar or two​@@sniggitty

N52 is prettily much indestructible. Mine is a 2011 and a little over 75k so it’s got a long life ahead lol

Liqui Moly is good oil.

@@DannyGrc My 2013 has the N20. I wish they kept the inline 6 goodness of the N52 for the F30.

@@ginog5037 the car jumped timing. It is an interference engine, so the valves were bent from hitting the pistons.

@@ginog5037 good luck getting any compression out of that engine. Good lucking even turning it over 🙄

I enjoy Jonny's video's too but I think if he had a choice he wouldn't be doing them. I just get the feeling that being in front of the camera isn't his thing.

@@jp-nq5wd Agree- that's probably why there were no new ones for three months.

he seems to be making enough income. some customers just do not care about price

Me too !!! I always learn something from the Ninja.

its designed that way so this repair eventually happens to all GDI's , its called planned obsolescence . So essentially, Greta grenaded this guys engine .

True, Euro spec gets both GDI and Port injectors. The reason VW does not do the same here is US is not as strict as Euro 5 requirements. Absolute BS .

I'm no mechanic, but if the oil change interval was too long wouldn't we also have expected to see some varnishing on the heads? Or is that only old oil and doesn't happen with fully synthetic?

I think lack of oil changes allows excessive carbon build up in the oil. This jams the oil control rings starting a cycle of oil burning and carbon build up. Detergent in the gas helps keep the rings free a little bit also less EGR necessary with the right octane. All these modern engines are a bit sensitive with small clearances and passages.

In Europe walnut blasting the intakes is standard maintenance. Oil changes and the correct fuel prevent exessive carbon jamming the oil control rings.@@5thelementcannabisproduction

I change my oils every year, including transmission oil 🤔Dunno if its overkill but its a volvo with aisin automatic, not most reliable autos and im at 333whp, and alot of people said they can handle around 300whp 😔

They tanked so fast. I bought a '15 that the original owner paid $41k for. I paid $13.5 in 2019

Want to know bad resale value? Buy a Hyundai 🙄 what a freaking horror show

9 months/7k mile oil changes with the correct spec oil are about right. Any earlier and it's overkill but leave it longer and the oil loses the properties required to lubricate and protect the various components adequately

My car doesn't even run right on the cheap gas 🤔

It’s cheaper in the long run

I agree. I have burned nothing but regular for 15 years in my Toyota’s and Lexus’s and no carbon issues at all. Computers can compensate for lesser fuel. If a car is having carbon issues it’s die to the fact that the engine was designed properly and gas and oil changes can only do so much. At the end of the day, folks…if you want reliability and durability I would not be buying anything from Germany.

@@jbphilly1234 My wife’s lx570 calls for premium, guess what, we run it on regular and it runs great. It’s a 100k vehicle and I don’t lose any sleep that regular fuel is detrimental. The computer, again if designed correctly, compensates. Instead of having 381hp it puts out 376hp according to a Toyota engineer I have spoken with.

​@@hokie9910the engine uses port injection not direct injection

@@maxheadroom224 Even the Toyota’s and Lexus’s that use direct injection run just fine with regular gas, because why,,.they know how to engineer them correctly. Oh and they use port and direct injection together so they don’t have the carbon issues in the first place. BMW and Mercedes, please stop your insanity. We all know you make crap cars and most people lease them and then the poor guy who doesn’t know better buys it used and thinks he’s getting a great deal. Look I just bought a 70k bmw for 25k, then over the next year he spends 10k in repairs, and repeat every year after until someone like Hoovie comes along and buys it 10 years old for peanuts to make a video to pay for all of the repairs while caught on camera to make us all laugh.

@@jbphilly1234 High octane fuel is only necessary to achieve the power rating advertised by the manufacturer. Otherwise, the PCM is listening for knock all the time and will just pull timing if it is detected and you make less power. That's it, that's all. The low octane/high octane thing is a myth that just will not die... it has not been a thing since the advent of EFI.

??????

Because engine oil is carcinogenic. Wear gloves and wash your hands regularly

@@jbphilly1234 Skin is the largest organ, by surface, of the human body. It will absorb to varying degrees ANY fluid that is placed on it. Hydrocarbons/petroleum distillates are not substances that are recommended for human contact. Used hydrocarbons, even more so. Having one's hand soaked in it for hours and hours on end, every day, day after day, is just asking for trouble...Modern day humans are sometimes exposed to dangerous chemicals in situations that cannot easily/cheaply be avoided. Wearing protection gloves is not one of them.

That isn't what caused the timing chain to jump. When oil changes are too infrequent it causes the timing chain to wear and "stretch". This causes loss of tension, and that loss of tension on the timing chain is what allows it to "jump" teeth. The cheap gas doesn't have some of the detergents better gasoline has which helps cut down on carbon deposits and other contaminants inside the engine. Combine that with infrequent oil changes and you're just circulating a lot of extra abrasive material inside the engine, wearing critical parts sooner.

@@costasmandylor7252 lol, how does a lack of detergent in the fuel help carbon buildup on a direct injection engine, where the valves never see ANY fuel. Talk about some bad info.

Oil circulates throughout the engine. And there are more wear points in the engine than just the valves. Re-read the original question. What doesn't get burned off in combustion ends up in the oil. The more contaminants in the oil, the more abrasives grinding on the working parts of the engine. Better gas burns cleaner and the better additive package reduces the particulate contaminants in the engine that then ends up circulating around in the oil. Better gas and better OCI's = less timing chain stretch, which keeps it from jumping teeth and bending your valves.

The issue on the 09-12 Passat and CC is the shitty camchain tensioner. There was a class action lawsuit over it, and VW revised the design at least three times.

@@jondiaz3475 Unfortunately tensioners going bad is pretty common. Some manufacturers make it easy to replace them, like Honda on their K series engines.

Nothing wrong with the turbo, just hard to access.

@@n9wox turbo sucks.

​@@n9woxThink about it. Flogging a tiny l litre engine with a turbo attached is going to wear it out sooner than a bigger engine.

Nah you can go 6k with modern synthetic oil and changing the filter each time. My 2008 nissan 350z has 250k miles and I’ve done them for 10 years now

Well I don't know about the repair history of your vehicle but hopefully the previous owner did a lot of repairs so you do not have too! Take it from me I have a VW 2012 with the 2.0 T engine and those cars are really problematic with high repair cost! Hopefully you have a little extra money in the bank and a good cheap mechanic that works on VW

@@bh2155thanks. I have a E60 M5 as well, so I’m used to the pain of maintenance costs 😂
