Tools Required

1. Remove the left hand cylinder head. Refer to Cylinder Head Replacement - Left Side .

Caution: Wear safety glasses in order to avoid eye damage.

Caution: Compressed valve springs have high tension against the valve spring compressor. Valve springs that are not properly compressed by or released from the valve spring compressor can be ejected from the valve spring compressor with intense force. Use care when compressing or releasing the valve spring with the valve spring compressor and when removing or installing the valve stem keys. Failing to use care may cause personal injury.

Important: Keep the valve train components together and identified in order for proper installation in their original position.
