@@Diagnosedan Hi Dan I have a question for you. I am looking to buy a new diagnostic tool and scope 2 channel would suffice but 4 channel would be a bonus . I am currently using delphi and an older launch x431 system I currently have no scope.. I want a machine that will work well with euro vehicles and popular Japanese models I have a budget of about €2000 euro. Is there any machines you can recommend that have some sort of future proofing I don't want to have to replace it in 2 years for a newer model. Any help would be great. I need biodirectional control and the usual service and dpf scr functions I don't need immobiliser functions to much as I have a friend that does most of my immo work for me.

The first shop tech was not observant of the fact the bearings were badly damaged, but didn't wonder why wasn't there any oil? Oil should have filled the turbine and compressor as the bearings were totally gone, so are the seals. This was a very lazy mistake and the customer should get his money back.

Very common to also see those soft lines collapse after about 8-10 years. The fluid works its way in behind the liner and it closes down. Same with brake lines. Don't want to reuse them when replacing the caliper unless you want smoking, red-hot brakes later on down the road.

Dan: When was the last time you had an oil change or service? Customer: What do you mean by 'oil change' ?

[@panzerveps]

This was a common problem on Audi 1.8t engines a while back. Usually a problem on cars that only did short commutes. We always changed the feed line and did an oil flush when changing the turbo on these engines.

[@Diagnosedan]

😂😂👍

[@nateh1974]

panzerveps - hi, question, is there a difference between a oil flush and oil change? Since there was a blockage due to carbon build up, is that owners fault for not doing the oil change/ flush OR a design flaw from car manufacturer?? Thanks

[@tiredoldmechanic1791]

@@nateh1974 Since they included a new oil line with the turbo, it is likely that it is a common problem. Is there a hose in that line where it is insulated? If it is a solid steel line and they had to insulate it, it is in a very hot area of the engine. The oil left in the line is getting very hot when the engine is shut down so it burns some oil onto the inside of the line as carbon. At some point, the burned layers come loose, plug the tube and ruin the turbocharger. Turbocharged engines need to be idled before shutting down to allow the turbo to cool down and slow down while oil is still flowing through the bearing. Manufacturers should be using systems to idle the engine before shutdown. A larger line with more insulation and a couple of minutes cool down might be the fix.

[@emilschw8924]

@@tiredoldmechanic1791 Or an electric oil pump which will circulate oil to the turbo after shutdown for two minutes or so. Some cars have a thermocouple which will let the radiator fan run for a while after engine shutdown to cool down the water in the radiator and engine, so why not the same for a turbo?

I think what Dan combines is the best of old and new school thinking. Before diagnostic ports were a thing, mechanics had to work out everything by sight, sound, feel, smell and logic. In the modern era, all most go by, is what the OBD2 tells them. If you are an apprentice in the modern era and want to become great at what you do, I would really recommend you make classic cars your hobby.

[@danrickard1911]

It appears the oil cooked (or coked) in the feed line due to high heat after the car was turned off, possibly due to, extended oil change intervals, or improper oils being used. It is always a good idea to use the best synthetic oils (synthetics can tolerate high heat much better than straight mineral based oils), and change them at a minimum according to manufacturers spec. Even better, idle the car for two minutes after a prolonged highway run to allow the turbo and exhaust system temps to cool down in the vicinity of the turbo to prevent coking on the bearings and surrounding oil lines.

[@Diagnosedan]

I agree!👍

[@peterplantinga2127]

Keeping the oil feed and return pipes below 200°C is the best solution. Even synthetic oil will form carbon build up above 250°C.. Oil change interfall will have not so much influence. Cooling down is good procedure, but it would have been better when the engine designer would have prevented overheating by f.e active cooling after shut down.

[@steveflor9942]

Agree completely.

[@brianburns7211]

I work on the railway. Most modern locomotives of course have turbocharged diesels. One safety feature which they have is a oil pump on a timer. When the diesel is shut down, A pump connected to a electric motor starts running. Based on the large size, the pump timing circuit runs for about a half hour. It’s too bad that auto manufacturers don’t have a pump to send oil through the turbo for a few minutes after the engine shuts down.

[@danrickard1911]

Brian Burns ; Absolutely! Oil pumps for pre oiling, and post shutdown are available for turbocharged vehicles. There are also programmable shutdown delays for turbo engines. Unfortunately I have only seen them for diesel trucks here in the US. I fly helicopters and airplanes with turbine engines, and it is a standard to allow a minimum of a two minute cool down at idle before shutdown to prevent coking of the turbine bearings.

What a great find! A knowledgeable, experienced Mechanic and Workshop Owner, carrying out Professional diagnostic fault finding to determine the origional cause of failure, unlike the first workshop which simply replaced the worn out component with a new one without actually checking for the cause of failure, thereby ensuring the failure of the new component too! Personable, Professional presentation and narration, excellent videography, lighting and editing, and a beautiful, clean Workshop in which to work. It's nice to see Professionalism at work, and I hope the customer was able to get a refund from the cowboys that failed to even look for the origional fault! What was especially damaging for the cowboy workshop is that the Oil Supply Line that came as part of the Turbo Kit the customer paid for, wasn't even fitted back onto the car, the original, faulty part was. That you contacted the Turbo supplier and determined that they had supplied the OSL and that the garage had not fitted it was absolutely top work. As a former Motorcycle Mechanic and Workshop Owner I am delighted to see your excellent workmanship. It was because of Professionals like you that I went to Technical College and opened my own Workshop. Subscribed.

Dan is so to be congratulated for always getting to the bottom of *why* something happened. It is this mentality that has been completely lost, people just don't to bother enough. I am writing from the UK also, all the shops care to do here is quick "repairs" of the type change a battery, an exhaust or, at max, the clutch assembly. They damaged our car when we took it for service and now it vibrates at idle. The internet says it is either the ignition coils or the electrical connectors to it. I 've changed the coils with original ones at 150GBP. It still vibrates. When I saw how one of the technician was pulling the connectors to disconnect the coils on another car, I understood what had happened. So we now have a car which is vibrating at idle, they won't even care to look into it and even if they did, I am 100% they would be incapable to trace down which exactly cable they 've damaged.

[@thefirstdutchguy]

great video Dan, to answer your question, it's a combination of things, first of all I think the oil change in the past has either used a wrong oil, or a too long interval.This resulted in the first carbon build up in the pipe.Because of this carbon build up, the oil feed drops and increases temp, and increases carbon build up etc. etc finally resulting in a total blockage of the feed. remember that a bearing only needs oil feed, pressure is less important because the oil in a bearing builds up its own pressure(hydrodynamics). Looking forward to your next vid!

The oil lines should always be replaced when replacing any turbo. That is why the manufacture of this turbo included them with the turbo. Especially on an older or high mileage vehicle no exceptions. The oil lines on old turbos will always have some amount of crusted up in them. Even if they are not blocked these lines live right on the turbo which gets incredibly hot and have a flexible center section made of some sort of rubber which will almost certainly spring a leak after being removed and reinstalled. The first shop needs to refund all of that customers money. Made even worse with the fact that they had the new oil pressure line right their in the box.

Since its obvious a huge mistake was made in the previous work station. Very curious if the customer can apply for the refund of the new turbo and work hour inclueded.

The oil supply and return lines need better protection from the exhaust heat to prevent the oil from baking onto the inside of the lines and building up to become a blockage over time.

[@TheFrenchPug]

That sounds good to me. My mechanic always told me to not shut the car off right away after driving it hard. So the oil doesn't cook inside the turbos

[@Diagnosedan]

Great advise 👍

When is worked for GMs customer service department, we had a customer with an engine failure at 50,000 miles. Engine tear down revealed oil more like tar. Customer stated they had never checked or changed oil since new. She stated why should I, I never did anything when I owed Hondas!

[@Diagnosedan]

😂😂👍 thanks for sharing this story👍👍

[@poiiihy]

😳🤣🤔

[@poiiihy]

i wonder how long she drove hondas without changing the oil. and they survived?? 😳

[@danthecarman8440]

Basically the engine probably never had an oil change causing all that sludge. Even with a new feed line that engine wont last long unless you take the sump off to clean it

[@Diagnosedan]

That's why you need to check the oil flow and pressure at the turbo.

[@jean-pierredeclemy7032]

I understand oil clagging to be a known problem with this engine. I have just had the sump removed and cleaned on my wife's cabrio because we had no service history when we bought the car. Whilst they had the sump off they also checked the main bearings which were 'like new'. We intend keeping the car and store it every winter. We are lucky to have a Saab specialist just in the next village. As Dan so rightly commented - you should only use a fully synthetic oil.

[@ExternalInputs]

If it never had an oil change since 2005 it wouldn't have made it to 2020, not even close.

[@djr3485]

Another great example of why the trend in extended oil drain intervals is complete nonsense and ends up costing in the long run. Great video as always!

When I used to work on multi million dollar jets, we would always put down a shop cloth before laying tools or parts on the airplane. On the really expensive jets, we'd use silk shop towels. The cost was offset by all the champagne and cheese we'd steal out of the fridge.

[@Diagnosedan]

I’m thinking the oil line is possibly too close to the exhaust system.

Thanks once again, Diagnose Dan, excellent work on your part; although we had to eagerly wait for quite a while for a new video from you (like children waiting for Santa Claus), but alas, we were happily rewarded, thank you so much !!

[@Diagnosedan]

Thanks for waiting😂😂

[@HandyC]

Haha winning comment then, perfect internet diagnosis... however..... I changed a turbo and a like a good boy changed the feed and return pipes like a good technician should, the only problem was, it was the brand new pipe that was blocked with what looked like the zinc coating. DOH! So don't trust the new parts either.. 😳🙈😭💩

[@SerbanCMusca-ut8ny]

Yep. Always check, never trust.

surly have to remove oil pan to check oil pick up pipe aswel after seeing this

[@Mtematiks]

So true ! As the next damage will be the cylinder head and cams! Something quite common on the 2.0TFSI EA113 Audi/VW engines!

[@boobalew]

There was oil flowing to the supply pipe. Why remove the pan?

[@andrewlaw]

The Ecotec engine in this is not so prone to sludging in the pan like the B205/235 fitted in the 9-5 which was a real PITA for PCV issues but it's not gonna harm it. Any 9-5 owner will tell you to use the spec'd Mobil 1 oil but change after max 10k miles.

@@boobalew Just a good grade of detergent oil like Red Line, new oil filter and change whenever dirty on dip stick.

[@nickpappas4133]

@@Mtematiks and very common on the Audi 1.8 turbo motor and in North America we put on a screw on VW diesel oil filter as it holds more oil.

[@michielhamerslag1244]

It will be a combination of very high (oil) intervals. And maybe a defect of the EGR system. The EGR is a high load for the oil and additives. Even as a engine with compression problems.

No EGR in B207L and B207R ;)

That amount of coked oil in the line is likley due to higher service intervals (manufacture recommended) over a longer period, or just a lack of maintenance. As a tech/advisor/svs manager, we recommend an additive flush every 2nd service on turbo vehicles, because it was becoming all too common for mercedes Diesel engines to have blown turbos (and eventually engines) by around 100k... even when the customer was following the maintenance schedule. My personal vehicles, I have always monitored the color and smell of the oil and would change it early if it started to smell/look burnt. I was the manager of a shop trying to calm a traveling customer down in this Same scenario. The tech felt like he couldn’t have known, but Diagnosis Dan shows everyone how to do it right! Great video Dan!

[@rickgalla3377]

Dan u did the right thing from the start, I also check pressure and flow before replacing any turbo, Thanks from New York city

[@jeffryblackmon4846]

I'm guessing the oil manufacturer's change intervals have been exceeded. 49 years ago I worked as a VW mechanic. It's been a long time since I have seen pressures expressed in BARs. Very comprehensive video, Dan and Thanks!

[@Diagnosedan]

Thanks Jeffry!

[@davebell6942]

Turbo oil feed line has a heat shield, which doesn't cover the line far enough, you cut above the shield and it was blocked. Root cause analysis would indicate the shield should extend the length of the pipe passing the exhaust manifold. Either reroute the pipe or add a shield and also flush the oil at each change with oil flush. This causes an issue with hydraulic lifters and hydraulic chain tension systems for years, a higher mileage (km) vehicle truly benefits from a oils flush before each change for this very reason, 50,000km plus. Very nice video thank you so much for the work you put in !
