1/2 Moon Replacement (heads)

Featured Replies

I need to install the 1/2 moon plastic peices 2 per head they fit in the corner. What is the proper method? Thank You

Maybe I am ignorant but could you describe what you are working on? If you mean the 1/2 moon pieces by the cams then I believe you put them in place with some good permatex sealant around the edges.

I am replacing the HG on my 2.5. They are the little black plastic peices in the corner. They look like they had grey sealant. The engine shop said I should use glue.

Use Permatex Ultra Gray 599 sealant. Thoroughly clean the surfaces where they attach to the heads, use plenty of 599: too little leaks.

put a little dab of the sealant on the valve cover gasket anywhere it makes a sharp corner up or down (from the plane of the head) too.
