Introducing the JHMotorsports Timing Chain Rebuild Kit for your B6-B7 S4 4.2L V8
The local Audi service departments we talk to recommend performing this service when your vehicle reaches 100,000 miles, with that being said we've seen symptoms of various forms of timing chain failures much sooner than that. With that being said the chain system on these cars should technically last the 'lifetime" of the car but unfortunately for our customers the engineers who designed this setup were wrong and failures occur regularly much earlier than even 100k. We are just here to help with parts and information to help you make your own decision based on the actual facts of what happened with these cars in the real world. This is in addition to the calls we receive from our customers on a weekly basis regarding some form of timing chain issue with their car. We have regularly seen the famous chain knock on cold start with cars that are quite new. This has been accepted by most due to its normalcy. The big concern is when they knock on warm restarts and can slap and damage other components or collapse at high rpm. We have also seen complete failures of guides and or the mechanical cam adjuster as early as 50k to 80k. Guide failures can lead to more damage to other components. If you have one mechanical cam adjuster fail, it causes one half of the motor to miss fire and sometimes damages the very pricey electric cam adjuster actuator which is included in our FULL and FULL plus kit. With that being said if your car has made it to 100k with minor or no issues it isn't a bad idea to do the service regardless to prevent damage to other components or getting stranded by a car running on half the cylinders. We see and hear of VERY few that fail in the 110k plus range. That doesn't mean they do not last on some cars, we just get more calls and local work on cars under 100k.
We have put together 8 different levels of Timing Chain Rebuild Kits to fit your individual needs for your repair:
- FULL PLUS:
This kit includes EVERYTHING you will need to complete your Timing Chain service. In addition to all of the o-rings, seals, and stretch bolts needed, you will also receive each of the 4 different chains that are required, 2x UPDATED Electrical Cam Adjuster Assemblies, 2x Mechanical Adjuster Units, all of the chain guides and tensioners required including an updated version of the guide that fails most often featuring additional reinforcements.

- '06 A6 40V V8 Basic Plus Timing Chain kit purchase
-
First let me say that JH Motorsports has in no way given me ANY compensation AT ALL. I paid for everything I received from them.
Second, I am quite happy with what my money purchased me.
Third, I think that JHM has done a great service to all Audi v8 owners by not just engineering and making available upgraded mechanical camshaft adjusters (camshaft phaser to Americans), but also making and releasing comprehensive videos on how to do the job(s) and why to buy their parts vs. other's.
There were no problems with my order other than I was expecting OEM timing chains, but received IWIS brand chains. I used the free shipping option (spent well over $99) on a Wednesday and it arrived via UPS the following Monday efficiently packaged with care.
NOW MY COMPLAINTS:
I am somewhat confused as to the consistency in pricing on some of the kits not accurately reflecting what is included.
For example: the only difference between the MINIMAL and MINIMAL PLUS kits is just (4) timing chains (OEM or ??) but the difference in price is $168, $235 difference between BASIC and BASIC PLUS, $219 difference between INTERMEDIATE and INTERMEDIATE PLUS or the FULL and FULL PLUS kits respectively. JHM offers the chains alone (OEM supposedly) for $252.
Some timing kits mention JHM-OEM vs. OEM but do not mention which components will be OEM and which will be aftermarket and who that supplier is. For instance, I ordered the OEM BASIC PLUS timing chain kit and my chains were IWIS branded vs. Audi/VAG/OEM.
So basically my complaint isn't so much of a quality issue vs. an accuracy and consistency issue. Oh, also the video mistakenly claimed that all timing chain kits included an M16 triple square socket for the camshaft sprocket bolts (which were included in my kit, thank you JHM) and you might consider adding info regarding which tensioners get the (4) new bolts, where the cyl. head timing cover-to-coolant crossover pipe seals that are included go and the accessory drive seal installation procedure is for the seal included in kit but mentioned only as an included part # and vague description.

Product Questions
I have a couple questions:
1:) Does this kit include the o-ring/seal for the intermediate chain's tensioner (the only tensioner that requires an o-ring, part #N90638402)? I see the green seal for the accessory drive tensioner, but not the lower/intermediate chain tensioner's.
2:) Why aren't the guides located between the intake and exhaust sprockets (Audi part #079109513D (2 are needed)) included in the timing chain kits? I would think these should be replaced along with all the other worn guides.
Thank you very much for all your help in getting my Audi A6 back to like new condition.
