Valve Lifter Oil Manifold Removal
WARNING: This page is about a different car, the 2017 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
- Do not lift the manifold by the electrical lead frame.
- Remove the valve lifter oil manifold bolts (506).
- Remove the valve lifter oil manifold (451).
- Identify the 8 gasket retaining strap locations (1 - 8).
- Using a wire-cutter type tool, cut the 8 retaining straps.
- Remove the outer gasket (556) from the manifold.
IMPORTANT:
Do not allow dirt or debris to enter the oil passages of the manifold. Plug, as required.
IMPORTANT:
Remove only the outer gasket from the manifold. Do not disassemble any of the internal components of the manifold in an attempt to remove the 8 inner sealing gaskets. If the inner gaskets are cut or damaged, replace the manifold as an assembly. Only use a wire-cutter type tool in order to minimize the amount of debris. Do not use a rotary-type cutting tool on the retaining straps.
