2. Insert the New Camshaft
Carefully slide the new camshaft into the engine block using the installation tool. Make sure it is aligned properly with the timing chain gear.
3. Reattach the Timing Chain
Reinstall the timing chain onto the camshaft gear, ensuring it is properly tensioned and aligned with the crankshaft gear.
4. Replace the Timing Chain Cover
Reattach the timing chain cover and secure it with the bolts. Ensure a good seal with the gaskets to prevent oil leaks.
Final Steps
