Installing Skunk2 Camshafts on the J35: Step-by-step Guide and Performance Gains

Installing Skunk2 camshafts on the J35 engine can significantly enhance performance and responsiveness. This guide provides a detailed step-by-step process for the installation, along with the expected performance gains.

Tools and Materials Needed

  • Skunk2 camshafts
  • Socket set
  • Torque wrench
  • Engine oil
  • Camshaft installation tool
  • Gasket set
  • Timing belt kit
  • Shop manual for J35 engine

Preparation Steps

Before beginning the installation, ensure you have all the necessary tools and materials at hand. It’s also important to work in a clean, organized environment to prevent any loss of components during the process.

1. Disconnect the Battery

Start by disconnecting the negative terminal of the battery to prevent any electrical shorts while working on the engine.

2. Remove Engine Covers

Remove any plastic engine covers to gain access to the camshaft area. This usually involves unscrewing several bolts.

3. Drain Engine Oil

Drain the engine oil to avoid any spills when removing the camshaft. Make sure to use a suitable container for the used oil.

Removing the Old Camshafts

With the engine prepared, you can now proceed to remove the old camshafts. Follow these steps carefully to avoid damaging any components.

1. Remove Timing Belt

Loosen the tensioner and remove the timing belt from the camshaft sprockets. Take note of the belt’s position for reinstallation.

2. Unbolt the Camshaft Sprockets

Using the socket set, unbolt the camshaft sprockets. Keep the bolts in a safe place for reinstallation.

3. Remove Camshafts

Carefully lift out the old camshafts. Be cautious of any bearings or seals that may come loose during this process.

Installing Skunk2 Camshafts

Now that the old camshafts are removed, it’s time to install the Skunk2 camshafts.

1. Lubricate New Camshafts

Before installation, apply a small amount of engine oil to the bearings of the new camshafts. This ensures proper lubrication during the initial start-up.

2. Install New Camshafts

Carefully place the Skunk2 camshafts into their respective positions. Ensure they are seated correctly in the engine block.

3. Bolt Down the Camshaft Sprockets

Reattach the camshaft sprockets and tighten the bolts to the manufacturer’s specifications using a torque wrench.

4. Reinstall Timing Belt

Reinstall the timing belt, ensuring it is aligned correctly with the camshaft sprockets. Adjust the tensioner to secure the belt.

Final Steps

With the new camshafts installed, there are a few final steps to complete the process.

1. Refill Engine Oil

Refill the engine with new oil to ensure proper lubrication of the new camshafts.

2. Reconnect the Battery

Reconnect the negative terminal of the battery, ensuring a secure connection.

3. Start the Engine

Start the engine and listen for any unusual noises. Allow it to idle for a few minutes while checking for leaks.
