Thanks everone for all the help on my head gasket change adventure. I have one more problem. Bentley does not explain how to remove the adapter for the rotor. I need to remove the top timing chain cover. I assumed the rotor adapter required a hex wrench and it need to be turned counter clockwise. However, I concern stripped it using the hex wrench. I can't see how it is connected because radiator is in the way. Any suggestions would be greatly appreciated. Thanks. Todd Q.
