• I found an oil link in one of my cylinder head bolt does this warrant a head gasket replacement? I am just planning to unbolt just the one that is leaking
  and put silicon into it and re-torque.
  
  thanks

• That's what my guess would be.  The silicone may help for now but if the gasket has desintegrated (sp?) that far then it's going to keep getting worse.

• This is not a job for a newbie right? I can probably dis-assemble the whole thing, But putting it back together  :roll:
  
  I am not getting the following
  1. milk shake looking oil
  2. white smoke
  3. bubbles in the radiator - I disconnected the hose from the reserve tank and placed it in a bottle of water and revved the engine. I did see very tiny bubbles. How obvious are the bubbles suppose to be?
  
  I have always thought headgasket degrade from the inside.
  I will try investigate further this weekend.

• I did a bit more checking. I found the was not through the bolt. It was comming from the valve cover and was just running down the bolt. I never realized it was the valve cover before because I just replaced the gasket a few weeks ago.
