Afterward I am going to replace the coolant pipes to the engine block, knock sensor (this is not normally a maitenance item but I changed it out anyway) and the VANOS oil pressure hose

Here is the picture of the engine block coolant holes

The coolant pipes were fragile and had brown/oily residue. I am not sure what this is about so I took a picture

here is a pix of the new knock sensor (ping sensor)

Make sure you order two crush washers per side for the high pressure hose (4 total)
