I was changing all 8 sparkplugs today but found about an inch of oil in #1 cylinder plug well. I need to order
new gaskets, but regarding the camshaft cover gaskets there are various versions, I guess, depending on
what the 'Change Point' is. I am not familiar with what this means and would appreciate (as always) any advice.

 

I bought this one and it worked perfect on my 2001 back in the day.

 

Check carefully if the brass threaded inserts are flush. If they have been pulled out and glued back in they can be proud of the surface and then the gasket does not seat and it leaks
