Where was the oil going ? Why was there blue smoke? Audi RS4 B7 engine teardown after 108000 miles 

I need a thousand lives to do what you do.... AMAZING JOB! IMPRESSIVE!

Loving the videos! Thank you for bringing us along, keep up the good work and keep these videos coming!

So well explained your findings/thoughts on this RS4. This walk through series of videos will be so helpful for potential new owners and existing owners. Love your work and channel🫶👍

Very detailed and well explained. Great video, looking forward to more.

Excellent videos, impressive walk through of the issues in a pedagogical way. Thanks for sharing 🙏

Another great informative video. Thank you. 💪🏾

Interesting that there was no timing chain guide issues on this car. Yet another reason to keep up on those oil changes. Can't stress enough how important this is. Great level of detail and another top notch video.

Thanks very much for sharing these insights and know how.. will be tuning in more ,, have B7RS4 30K miles,, aiming to keep it immaculate so great sharing.

Always awesome content on this channel 👏🏽 👌 thanks

Looks like this engine was ready for a refresh. The manufacturer would label all this as fair wear and tear. Great video, thank you.

interesting as always - learn so much from you - keep doing what you're doing - I'm going to need my timing chain done ( B8 S4 2014 plate ) so looking forward to getting that done

Car deserves full resto 👍

Fascinating. I really want to buy a B7 RS4. Watching with interest. Vibodnja. Djakujem bratku

As always a very interesting video

It’s always difficult as an owner to decide the stop point when maintaining a performance car like the B7 , personally given the colour and spec I’d do both sub frames and all bushes after the engine , paint correction then stick it away for 5-10 years and drive it dry weekends only , great work as always 👍

Once again a great video and great content. Impressive that after 100k miles the only main issues are in the heads/valves. I suppose this can be concidered as "expected" after this mileage on the RS4, or is it unusual to have occurred? Will it be a relatively cheap engine fix/refurb? Keep up the great work and content please.

Always great to watch , interesting to see a 100k is no prob on the bottom end , a lot to be said for regular oil changes ,,,, it will be better when its sorted though.

Just love your content - so insightful and you guys nearly know what you are doing 😂

Awesome video 🙌👌👍😊🍀

Very reassuring lads . I've one of the same age and mileage and as you say showing her age in places and you must treat her as such.Still absolutely epic though !

I didn’t realise the RS4 V8 had a trapdoor sump on it. Excellent video👍

Restoring my B6 convertible right now and although I have the 3.0 this was still very interesting. Both my subframes have been restored.

Every time I read or watch RU-vid, most people say: Change the oil regularly. If you do that, you will have an engine that works well.

This is very interesting for me b/c I also have a B7 RS4, currently at 145K miles. It's been well maintained, but I have an oil leak coming from 1 of the timing chain covers, which leaks oil onto the exhaust manifold causing smoke to billow from the hood. Obviously at the age/mileage I need to do the timing chain, but I kind of want to do everything while the engine is out.

sooooo Happy my rs4 is a summer car only less than 1500 miles per oil change :-)

Keep the tunes coming

Great commentary on the tear down. Oil change is by far the cheapest maintenance option, so I'd be doing these every 6 months regardless. Even though most of that engine is in good condition it would always feel like a wasted opportunity not replacing the wear and tear...ooops! Sorry, tear and wear items. After all, it's basically a new engine when you replace them all, albeit it is costlty for these beasts. I mean, what's a million pounds nowadays😂. Keep up the great content boys.. #WhereIsMiraslav?😂

Nice to see the engine and your commentary on its condition. For the piston rings, is that something where you'd put the piston itself in an ultrasonic cleaner to get the rings all cleaned up? Is it worth taking the rings out in case there's a fragile one that you find needing replacement?

good job

Super interesting stuff man. 👍 The cylinders look pretty good. But I'm not there. What about the pistons getting updated with aftermarket? Are there updated or better ones? I have bronze valve guides on my V8 intake and exhaust. The guide itself is pretty thick and sturdy. In my estimation this engine saw lots high RPM revving and the oil was too thin. The pistons did ok but valves were affected. I think the intervals were long but not terrible. I ❤your videos, music and lights and all. Please keep doing what you are doing for those Audi-lovers. Many things we love are not easy always. Thats life. Owners need to do their own changes using great oil and a Fumoto drain valve ..:or have you do changes for them

Interesting! I'm curious to see what the machine shop recommends with regards to the Alusil block.

It's expensive to overhaul a modern high-performance automobile. Very few people do it. It will be nice to have this car refitted and ready for it's second life. It will make for a nice cars and coffee story.

Just taking a tea break to watch this 😂

B7 RS4 needs saving and whatever work needs doing the owner will probably agree. The guides being worn so little is a testament to regular oil changes.

Mine has 192.000km bought it when it was 163.000km. Did a full rebuild, all chains, clutch, flywheel, new pistonsrings, cleaned the whole engine. Next up crazy all in on exterior. I do oilchanges after 5000km no matter what.

Looks like a well maintained engine apart from normal wear n tear. Boy that road salt really does eat up metal…😢

Interesting stuff. A better Mic would benefit views for sure.

Surprisingly little tear and wear on them rod bearings!

Great I guess that is a £20 k plus restoration but it is an exotic car

Found this really interesting, if I’m honest I’m surprised there is issues at such low mileage especially on a V8, but I’m comparing it to say the 2UR-GSE 5.0 V8 with 417bhp in the Lexus ISF which go 250k and still dyno full power without any issues besides wear and tear stuff such as Brake discs/pads etc. I suppose if you like the way the car drives you pay the big bills….to you guys 😉

Replace piston rings,valve seals, deck the heads and redo timing and good

Have you watched M539 restoration's vids about BMW Alusil block cylinder "resurfacing"?

Just Stop Oil... leaks

Nice video, if you moved your tool trolleys closer to car you’d save time and walking miles extra! 😂

There's absolutely nothing wrong with that block. Cylinder lining looks beautiful.

this car spent a lot of time in high rpms and it had was well looked after, i was expecting more damage like cylinder or bearings. for a year old car

I like what you do but I hate that there is far to much time laps filming going on, I would prefer to watch close up what your doing thank you Chris

What do you thing about A4 B9 2016 2.0 tdi 140kw 190 hp DETA engine what should I expect? Just replaced timing chain and water pump.

Great work! Question - Would you recommend someone to own an RS5 b7 b8? What are the issues with it? Any major headachs? Please advise because i planing on buying one.

Hello guys, after seeing your video ik have a question about the break in period. I have bought a new Golf GTI 245HP witch will be delevered in januari 2024. The car will be uses as a normal car, no racing. How do i drive the car for the first 1000 miles so i have the best change that the engine will not become an oil burner? I would appreciate your opinion a lot! Thank you for making the videos, it is so interesting to see you guys work!

Ware and Tear

Hi VAG Technik, what is the update on RS4 B7? Is it fixed now?

Call me old but I like to do oil changes every 3,000-5,000 miles and nothing more In a performance car you should and it’s good for it

0:49 built in anti rusting system… 👍🏻

Are them bores not Nikasil coated?

Quick question. Ive got an Audi RSQ3 2016....Ive had a small ecu tune put on it. After about 2 months a VERY small puff of blue smoke pops out on start up....but its not using any oil....over fueling residue from the tune?

I own one with 158k miles. Stilk runs.

Nice of VW to 'give' you so many crates 😂

Wear and Tear is the order, FYI.

At 10:43 I did not see the loads of oil. He could have installed 2 new cats and avoid this entire teardown?

Are the engine block the same as the BBK engine?

Aluseal cilinderbore?

im never gonna drive mine on the winter with alt that fucking SALT on the roads here in sweden :D

What did this run ($$$) the owner?

Smoke alarm in need of a service

That is a "poor" condition RS4, not "average". I'm at 142k without any of those problems.

Check for roll backs otherwise I don’t believe any Audi rs mileage Infact do a video on how too so people know what really goes on 😂

Should bought a Honda.

I’ve learned a lot from theses videos! #1 is don’t buy a Audi!

can you please invest in a lapel microphone, so difficult to hear you when you are at a distance from your camera.

Please say “wear and tear” not “tear and wear”….😜😜

Lack of service..poor quality oil..and poor engine design.all together make for a nightmare

Complete money pit 😂

Typical VAG product. Burns oil and wears out quickly. The Japanese are thanking the Germans for their poor build quality.
