Removal Procedure
Important: Organize the valve train components when disassembling so they can be reassembled in the same location and matched up with the same
components, as previously installed.
1. Remove the cam cover.
2. Remove the spark plugs.
3. Remove the exhaust and the intake sprocket bolts.
4. Install the J 44222 onto the cylinder head in order to keep from disturbing the timing chain components.
5. Adjust the 2 horizontal bolts into the camshaft sprockets to maintain chain tension.
6. Carefully move the sprockets with the timing chain, off of the camshafts.
7. Remove the camshaft cap bolts.
8. Remove the camshaft caps.
Important: Place the camshaft caps in a rack to ensure the caps are installed in the same location from which they were removed.
