Now I have searched but I still have a few questions.
From the write up on removing the timing chain guides
http://www.nicoclub.com/articles.php?id=105618, he says that when replacing the gasket apply RTV to the semi circular portions of the gasket with about 2-3mm layer as shown in the picture. The question: Is there anywhere else that i need to put RTV so that the valve cover will not leak?
Question 2, After removing the top chain guide, do I need to do anything else with the holes left over from the bolts or do I just leave it? This question is more curiosity and I am just wondering what others have done.
Thank you and hope to hear some answers soon.
