Well I bought the Permatex Right Stuff sealer and applied it where the leak is. It didn't work and the leak came back. So I decided to replace the head gasket. But wait, before I do that I'd like to hear some opinions. I have attached a picture of the engine from where I am now. After further carefull checks, I could not find any leak coming out of the head gasket (front corner as I stated on my original post). The front seal was already replaced three years ago but that did not solve the problem in the first place so, I just live with it. Now I decided to find out what really causing this messy leak. Any idea on where the leak is coming?
I hope the picture will help.
