TECH TIP:MINI Cooper S R56 Engine Rattle Noise

Timing Chain Removal & Installation Summary with Video


MINI Cooper S R56 Timing Chain Rattle Noise from Engine

Early symptoms of chain tensioner failure on the R55, R56, R57 models consists a slight rattling sound from the passenger side of the engine valve cover, even with engine running but not driven. The rattle sound will increase with speed, but go away when the engine reaches approximately 1800 R.P.M. The sound will return when the engine returns to lower R.P.M.s during deceleration or idle. In early stages this sound may be more pronounced at colder temperatures, but in more severe cases the sound and vibration will be heard at all temperatures.

MINI Cooper S R56 Engine Failure

Common MINI Cooper S R56 Engine Failure:
This failure is the result of a weak or collapsed timing chain tensioner. If driven for an extended period of time the results will be a broken plastic tensioner rail or upper guide rail.

The noise you are hearing is the loose timing chain resulting from a collapsed timing chain tensioner. The slapping action of the timing chain will eventually break the tension rails. This condition will also effect cam timing and risk an eventual chain failure.

The chain will also need to be replaced at the time of repair in case of stretching or elongation. We do not recommend driving a vehicle in this condition other than at low R.P.M. to a nearby repair shop.

A diagram is provided below for quick reference of the timing chain components and their orientation or location on the engine.

How to determine if the engine noise is a bad timing chain?

MINI Cooper S Exhaust Systems

DIAGNOSIS PROCEDURE Work through the following to eliminate other causes.

  1. If a Fault is stored in the DME memory (e.g., misfiring,VANOS, etc.), then work through all the relevant test plans first.

  2. A one-time short shrill will be heard within the first two seconds of engine operation. This is an inherent noise caused by the first regulation cycle ofthe engine oil pump. Tis is normal operation and no parts should be replaced.

  3. If the noise appears to be coming from the valve cover or the vacuum pump area, refer to SIM11 02 08. To verify the source of the noise, disconnect the vacuum hose from the mechanical vacuum pump to eliminate the knocking noise. This is not a failure of the mechanical vacuum pump; do not replace any parts.

  4. Ensure the noise is not created or eliminated by depressing the clutch pedal, if equipped.

  5. Disconnect the electrical connector from the tank ventilation valve. If the noise disappears when the connector is removed, reconnect to verify whether the noise returns. If the noise returns, replace the tank ventilation valve.

If ALL of the steps above are unsuccessful in eliminating the noise, start the Timing Chain Removal and Inspection process:
To remove the timing chain you will need the MINI Cooper S R56 Cam Timing Tool Kit for N12/N14 engines Promini Part# 138007.(products shown fit 2007 model, please select your year for availablility).
This tool is used to avoid improper cam timing on MINI Cooper engines, the factory has devised a cam timing system that locks the crankshaft and cams into a specific position prior to cylinder head removal.

This method was devised to avoid any misalignment, resulting in piston to valve damage. Unfortunately without these tools re-timing the camshafts after a valve job is almost impossible. The factory specification manual does not supply installation specifications. (includes all the necessary components to lock the crankshaft and flywheel position as well as the cams).

MINI Cooper S R56 timing chain kit

To replace the timing chain you will need the following neccessary parts to complete the job: Complete MINI Cooper S R56 Timing Chain Replacement Kit Promini Part# 180846.
(note: we recommend replacing all of the timing chain parts while you have the engine apart to save time and money, and avoiding mixing new and old parts to ensure that you won't have to do it over in the future, and to keep your car in optimal running condition.)
Compatible with models from 01/2007 to 04/2007.

MINI Cooper S R56 timing chain tensioner To replace the timing chain tensioner only you will need the following part: Complete MINI Cooper S R56 Timing Chain Replacement Kit Promini Part# 180841.
(note: only removal the complete timing chain rail cassette is the only way to determine if there are broken pieces that will damage the chain operation.)

MINI Cooper S R56 crankshaft locking pin Step 1:
Remove the right-hand wheel arch trim to access the crankshaft central bolt.

Turn the engine by hand to move the flywheel to approximately 90 degrees before TDC. (Top Dead Center) Install the locating pin (see photo) (MINI Cooper S R56 Special Tool 11 9 590) to lock the position of the engine.

Step 2:
Remove the chain tensioner and collect the residual oil with a shop towel.
(The tensioner is located on the side of the engine block timing cover facing the firewall.)

Fit the timing chain tensioner tool (MINI Cooper S R56 Special Tool 11 9 340) without the seal ring and with the lock nut loose. Pretension the chain tensioner tool to 0.6 Nm, and finger-tighten the lock nut.


MINI Cooper S R56 timing chain tensioner tool

Remove the chain tensioner tool(MINI Cooper S R56 Special Tool 11 9 340) from the engine, with the lock nut still tight. Measure the distance (A) as shown. If the distance (A) is less than 68mm, then only replace the chain tensioner piston with BMW P/N 11 31 7 598 956.

If the distance (A) is 68mm or greater, then replace the following timing chain components:
! Important: Do not replace the intake camshaft VANOS adjustment unit or the exhaust camshaft sprocket.

Step 3:
Remove serpentine belt.

Remove the valve cover.

MINI Cooper S R56 timing chain tool Step 5:
Assemble and install the cam locking tool brackets.

Step 6:
Remove crankshaft bolt inside the crankshaft pulley whick allows for timing chain cassette removal.
Remove motor mount and the three bolts that hold the timing chain cassette assembly.

MINI Cooper S R56 timing chain engine Step 7:
Remove the old timing chain rail cassette by sliding the whole assembly up and out.

MINI Cooper S R56 timing chain sprocket Step 8:
Assemble the new timing chain rail cassette with the new crank sprocket held in place with the specially designed tabs. Install the three bolts that hold the timing chain cassette assembly.

Step 9:
Install the crankshaft pulley and bolt.

Step 10:
Install the new timing tensioner.

Step 11:
Remove the Cam locking tool.
Remove the Crankshaft locking tool.

Step 12:
Install the motor mount, the new valve cover gasket, and replace the valve cover to factory torque specifications.

Step 13:
Install the new serpentine belt.
