Step 1 To access all six spark plugs, we need to loosen the intake manifold. This will require removal of attached components.

• Unclip and remove the black insulating material
• Disconnect the three PCV tubes. Push the tab across and pull outwards

Step 2 Unclip the purge solenoid from the intake manifold. It slides off towards the firewall. Step 3 Unclip the throttle body loom and disconnect the intake pipe. Also unbolt the support bracket as circled. Step 4 Remove the five long bolts located on top of the intake manifold. The bolt closest to the front is shorter than the rest. Keep this in mind when reinstalling. Step 5 Next, remove the final bolt securing the manifold to the engine. You will need to unscrew this bolt entirely, however you will not be able to remove it from the manifold due to a lack of clearance. (This picture has been borrowed from an LFX engine. The bolt however is identical) Step 6 Raise the intake manifold and place an object underneath it to support it. This will provide enough clearance to access all the spark plugs. Step 7 Unclip all looms from the ignition coils. Simply push the grey tab downwards, then press on the connector and disconnect. Step 8 Unbolt the ignition coils and remove from the engine. Step 9 Using a spark plug socket and breaker bar, gently remove the spark plugs from the engine. Step 10 Install the new spark plugs by applying a light coating of anti-size and gently thread them into position by hand. Be very careful not to cross thread the plugs. Tighten with a torque wrench to 20nm.

im assuming its a vy clubsport? Make sure you remove all the old fluid from clutch resevior and clean it out properly. You will need to raise the vehicle on a hoist or atleast 4 cat stands . you will need 3 people in total to get the job done correctly. fill the clutch resevior with new fluid. get someone to stay under the car to open slave cylinder to release air. someone to seat to drivers seat to pump clutch pedal. and someone at resevior all the time to top up fluid. when bleeding system just pump the pledal slowly when the person bleeding slave cylinder says hold.hold the pedal down with light pressure when the slave is open you will get air and then little fluid . repeat process until just good flow of fluid comes out ,once this happens you should have a good pedal.. hope this helps you
