Thanks guys for comments. Anyway I've found out that VQ Engines are prone to this issue. Here is the link from g35driver.com explaining everything.

Hi Guys
Yesterday I have changed my spark plugs and I noticed one of the spark plug covered with oil. My car is 01 V5 250gt with 116000km. Does anybody experience this before and what should I do? Is it serious problem?
Appreciate any help.
Thanks
