As a system specialist for engines, it goes
without saying that RUVILLE offers superior
components in OE quality for the Audi A4
TDI V6 as well. Which also makes installation
smooth and easy.
Please follow both the general and specific repair
instructions for the respective components.
GENERAL INSTRUCTIONS
Basic installation instructions:
Always use new seals and sealing rings and clean the contact and
installation surfaces
Comply with the replacement intervals specified by the manufacturer
Do not start the engine for approx. 30 minutes after installing the
camshafts
To ensure that the valves do not touch the pistons, the hydraulic
compensation elements must be given enough time to settle
To ensure that none of the valves touch the pistons when the engine is
started up, the engine must be carefully rotated for at least two revolutions
Hydraulic compensation elements cannot be repaired
Irregular valve noises during start-up are normal

In the area of the valve timing, irregular engine running and bucking may
indicate a gradual loss of engine power in some engines (AFB, AKN AKE,
AYM) over the course of time. This is most frequently caused by worn
camshafts and rocker arms with deep millimetre-sized grooves on the drive
cams, and starts happening after approx. 150.000 km. The result is a
continuously changing valve lifting curve, and proper gas exchange is not
ensured.
If servicing is required in this area, all components in frictional contact have
to be replaced. This includes the camshafts, rocker arms and valve clearance
compensation elements. If the cylinder heads themselves are not damaged,
they can remain in the engine.
In some cases, the clearance between the camshaft and rocker arms is so
large that the rocker arms fall out. If this happens, the pertinent valves are
no longer actuated at all. The rocker arms can fall into the oil sump via the
oil drain holes. The oil sump then has to be dismantled in order to remove
the defective arm. Rocker arms that have fallen out mainly concern the
exhaust camshafts.
Please note:
In the past, camshafts with a kilometre reading of 30.000 km were replaced
on several engine models. Only the normal grooves could be seen on these
camshafts, but they were not worn out. According to previous analyses,
material abrasion on the drive cams is non-critical up to 0.5 mm. Replacing
the camshaft is only necessary when wear exceeds 0.5 mm.
When mounting the camshafts, be sure to note the mounting position
of the bearing covers:
The bearing covers are consecutively numbered from 0 to 6.
Important note:
Be sure to pay attention to the
centre offset of the bearing
covers! To determine the mounting
position, the bearing covers
have to be put in place.
compensation elements (cam followers)
if noise occurs:
Procedure:
Start the engine and let it run until the radiator fan switches on once.
Increase the rotational speed to approx. 2,500 rpm for approx. 2 minutes.
If the hydraulic elements still cause noise, identify the defective elements
as follows:
Remove the cylinder head covers
Turn the crankshaft in a clockwise direction until the cams of the
elements being checked are facing upwards
Check the play between the cams and rocker arms
Press down the rocker arms with a wooden or plastic wedge. If there
is play between the cams and rocker arms, the hydraulic compensation
elements have to be replaced
Please note:
If the irregular noises disappear when starting the engine, but occur
again during short drives, the oil retention valve has to be replaced.

RUVILLE has developed 12 special water pump kits that also include the
thermostat. These kits can be used for almost all V6 engines from the VW
Group and some 4-cylinder engines from Opel. In the above-mentioned
engines, the thermostat is difficult to reach because it is installed directly
behind the timing belt. To replace the thermostat, the cam belt has to be
removed. If the thermostat gets damaged after the timing belt has been
replaced, the customer has to pay for removing and installing the timing belt
a second time. This inevitably leads to major customer dissatisfaction, since
the labour costs involved in this case are substantially higher than the price
of a new thermostat. Using kits that contain an integrated thermostat prevents
these high follow-up costs, and therefore increases customer satisfaction
at the same time.
Check the axial play of the camshafts:
Use a universal test gauge and test gauge holder. Take the measurement with
the rocker arms removed and with the first and last bearing cover mounted.

Maximum wear limit for
intake and exhaust
camshafts is 0.3 mm.
