Reasons to not buy an RS4

I often see this pic and ask my self: dafuq?

What is the point of this picture, to showcase the sophistication of the engine, or to show damage to the engine?

to show the "nightmare" it is to change the chain guides/ chains and everything
those 8 bolts hole sin the middle are for the flywheel, the chains are in the back fo the engine, and this makes it an engine out job

[shipoopi]

Just to show off the complexity and the nightmare that the timing chains can be when one of the guide rails snaps loose. You have to drop the motor to do any work on it, and it's a laborious disaster. If you can luck out in that ballpark and keep the valves clean you should enjoy it.

[Diamond Dave]

Regardless of looks, the B7 RS4 is quite a bit different than a B8 S4. By "stepping up," you lose the V8, the widebody, and the rarity factor - the top three things that are drawing me to the RS4.

I'm with this guy. Shallow but true.

I would even spring for an RS5 before a B8 S4 with the imaginary money I don't have.

The list would have been a lot shorter.

Yes, they sound cool..but they were only great in 2007. 420hp is easily outclassed in that car now and for the money..if it's even making that. I heard the sludge takes away up to 50whp. And don't they barely beat S4 times?

I'm just saying, for the money..there's C63 AMG, E55..Pontiac G8 GXP..CTS-V.. B8 S4...335xi with a tune..

I know this is going along with the "Step 1; step 2" post from the last page, but - I love all of those cars, but the more I think on it, the more I realize that none of them do "it" for me like the RS4 does. This could completely change after I drive one on Monday, of course.

I think if I was going to buy anything else, it would be a C6Z, but obviously that isn't the most practical car to have as an only car. Insurance would probably go up considerably more than the $19/mo that the RS4 bumps it, also.

If you do not look at that picture and cringe over the thought of working on it, than you must not turn wrenches.

I hope you're not talking about the carbon on the valves because if you are, you are foolishly wrong.

So much FAIL in this thread I'm not sure where to begin. Anybody that is truely interested in one of these cars would probably be smart enigh to check the RS4 specific forums and do their due diligence on the car before purchase rather than research the car lounge but I'll add a bit to clear some misconceptions.

Like all DI engines, carbon deposits build up around the valves. Its essentially a very light mist that ends up hardening over time and building up. I know this because I have had an IM off less than 200 miles after a cleaning....

And regarding the process of cleaning the valves - it is extemely easy. It takes some time and muscle depending on how long the deposits have been left to sit, but it is something that any monkey with a few tools can do. In fact, to take the IM off you don't need any special tools at all.
I am by no means a mechanic but I have done my own carbon cleaning and it was as straight forward and easy as any wrenching I've ever done. Before that, all I'd ever done were basic bolt-ons, swapped in a K04 turbo on my Gti, full alcon brakes on the Audi, and other routine stuff but that is mostly it. And I know I'm not mechanically inclined, but paying someone else to do the carbon cleaning after I saw how easy it was was not going to happen.

The pics OP posted are very famous and are of an engine with almost 75k miles if I remeber correctly. Here are pics of mine at 17k miles - the layer was very thin and had not hardened too bad. I let Seafoam sit in each cylinder bank overnight and cleaned two cylinders each night when I got home from work. Total time if I had a free weekend would be about 6-7 hours. Now that I have done it before I can probably take an hour off of that time.





Really not too bad.

Yes, it is a PIA to have to do, but most owners of these cars and most of the people on this forum are car enthusiasts. Many RS owners look at it as a annual maintenance item that needs to be done to keep your car running in tip-top shape. You don't have to do it, but your performance might suffer.
You also don't have to change your oil or tires either but..........

Yes, you can argue that you shouldn't have to do something like this on such an expensive car but guess what....all the 997.2 owners, Cayenne and Panamera owners with DI have to deal wit the same thing.

These are from an 08 Cayenne Turbo:

And I don't care what any of you experts say, fuel additives and meth doesn't do sh*t to help it at all. It has been tried and anyone telling you it works on the RS4 is a liar. Some people have tried to come up with a device to spray a touch of fuel in before the ports on the IM and pass over the valves but we are still waiting to see the results. But as of right now it is something that you deal with. Every car will have it ups and downs. What you do is balance and weigh the harm/benefit, the good/vs bad. All in all, I am very happy to do some extra maintenance and get to know my car more intimately once a year or so if it allows me to drive and own such an awesome car with a smile on my face. Basically, to me, the overall benefits of the car far outweigh this problem.

Now, I am quite a few thousand miles away from talking about the timing chain but that is for the dealer to handle when time comes but it is not something I'm worried about since the RS has updated guides and tensioner's and is very different from the S4. I am not trying to 'sell' the car to anyone, in fact those that know me know I couldn't care less what people think about my car choices, but threads like this is how misinformation and rumors can spread to those not in the know. Keep up the good info TCL.

You can see the valves in that picture?

And where would you get the idea that I was talking about carbon from my post?

[Baddass93TA]

I wouldnt trade mine for the world.

In all honesty, the B8 S4 might be a better choice? But they just look too damn boring

Just get a B8 S4. It is very fast and the Supercharged V6 is a tunable engine. My dad just got one with the DSG and sports differential and it is a beast of a car. I went into a tight s-turn going quick and the car would not lose grip.

The Supercharged V6 is a better engine then the V8. The B8 S4 is also less front heavy then S5 and older S4/RS4. The 7 speed DSG in the B8 S4 shifts so quick it is unbelievable and has launch control.

[DUBSfightinRUST]

OK..I am going to give you guys a bit of dangerous advice from days gone past. As far as the carbon thing goes, old carburetor cars used to have some pretty nasty carbon issues with the early emissions systems (before engineers knew how to actually get rid of the poisonous gases).

Old time mechanics - in which I apprenticed - used to pull a vacuum hose off and let the engines suck in tranmission fluid or "Marvel Mystery oil".

It worked on old American engines (circa 1975-1990) ,but could end up in an EPIC FAIL (i.e. ,blown engine/bent valves) - so ya might wanna ignore everything I am saying.

It did work on old engines ,yet the new engines are built to VERY different standards with different materials. >>You might want to try it out on your buddies car first!<<

[MightyDSM]

If the first 2 pictures in this thread are not enough to make you go like "f that" then I don't think there's anything that can persuade you not to get one. Maybe if it came with Acura Girl?

[jddaigle]

So to clean the carbon off you just take off the intake manifold and get in there with a toothbrush and what have you? Do you just let the carbon fall into the cylinder? Seems like you'd want to take the head off and do it on a workbench.

Couldn't care less about DSG, I won't own anything but a true manual. The new blown 3.0 does nothing but turn me off from the car, if they went back to a V6, I wish they would've brought the turbos back with it.

Scrub on it with the valves closed, vacuum it out.

To be honest i think the Supercharger is better for the S4 because it does not lag like most Turbo engines. Have you driven the B8 S4 yet?

Drove an RS4 today, there's no chance I'm not buying one as soon as the B5 is sold.

I have yet to hear an internet video that accurately conveys the sound of the exhaust.... it is that good.

B7 RS4 also has launch control...engage first, hold right foot down, slide left foot off the clutch.
