I took mine to the dealer showed them the plug with oil on it. the front driver side wet and they clam they have no clue why it is leaking so they added dye to it to pin point the leak.

Update?

so what's the deal with these, are they only trying to sell in bulk? i need to replace my covers immediately

what is the cost of the valve cover gaskit? on page 1 someone said they think its like 200 and suggested the maxima one for 40. on infiniti parts express they say 17 each side. am i missing something or looking at the wrong part? The part does NOT show anything that might resemble o rings. I'm scared to change my plugs. i have 143,000 miles on my 05 g35 sedan and have NO issues while driving or with my engine. Just worried when I change the plugs i'm going to see oil in #6 and will have to purchase this valve cover. does anyone have a part # I should search in-case I have a leak?

I know this is an old thread . Can not find the person that is modifying the valve covers with o-rings to stop the oil leaks around the plugs . Any help would be great .

There are 2 companies (r&d factory and L-fab) doing it but they both seem to be busy or low on covers.

You can get the full set of covers on Amazon pretty cheap. I've replaced mine already, and I'm doing it again. The cover design sucks. I'm using RTV on all surfaces this time because this is the last time I'm pulling all these parts off. This thing is getting injectors this time too.
