Once the timing chain is removed, unbolt the old camshaft from its position and gently lift it out of the engine block.
Installing the Nismo Camshaft
Now that the old camshaft is out, it’s time to install the new Nismo camshaft.
1. Prepare the New Camshaft
Before installation, apply a small amount of engine oil to the bearings of the new camshaft to ensure proper lubrication.
2. Insert the New Camshaft
Carefully place the new Nismo camshaft into the engine block, aligning it with the bearing caps. Ensure that it is seated properly.
3. Bolt Down the Camshaft
Using the torque wrench, tighten the camshaft bolts to the manufacturer’s specifications to ensure a secure fit.
Reassembly Process
With the new camshaft installed, you can begin reassembling the components you removed earlier.
1. Reinstall the Timing Chain
Reattach the timing chain, ensuring it is aligned correctly with the camshaft and crankshaft gears.
2. Replace the Valve Cover
After the timing chain is secured, place the valve cover back on, applying gasket sealant where necessary to prevent leaks.
3. Reconnect the Battery
Finally, reconnect the battery terminals and ensure everything is securely fastened.
Final Steps
Before starting your engine, double-check that all components are installed correctly and that no tools are left in the engine bay.
