Some would call the removal of your clutch delay valve as the ‘Ultimate’ modification for any manual vehicle. It restores the direct feel many manual owners would be used to, and allows you to change gears with maximum accuracy.
What is a Clutch Delay Valve?
A delay valve is an inline restrictor which blocks you from hard launches and rapid gear changes. It delays and slows the pressure being applied to the clutch plate, thereby protecting the gearbox but increasing wear on the clutch. Unfortunately this also creates a poor driver experience and unpredictable clutch movements.

We’ll now remove the bleeder block, which also houses the delay valve. Place a cloth under the clutch line and release both clips attached to the bleeder.
Once the clutch line is disconnect it will start to rapidly drip. You can connect your brake bleeder kit to the clutch line to ‘block’ the line and prevent dripping.
Connect a brake bleeder kit and commence the bleeding process. This is done as follows:
- Open the brake fluid reservoir and ensure the fluid is at the MAX line.
- Crack open the bleeder valve 1/8th of a turn.
- With the assistance of a friend, depress the clutch pedal whilst watching the fluid flow into the bleeder kit. You will bubbles in the fluid.
- Close the bleeder valve.
- With your hand, pull up the clutch pedal which would have become ‘stuck’ on the firewall.
- Top up the fluid reservoir, back to the MAX line.
- Repeat these steps until no more bubbles are flowing out of the bleeder valve.
