I was changing the spark plugs on my 2001 Maxima and I noticed that there was a noticeable amount of oil on the spark plugs. 2 of them were quite a bit worse than the rest, but they all had oil on them. I did some searching on this group and found this post: http://groups.google.com/group/alt.autos.nissan.maxima/browse_thread/thread/4ac7a3a8956f01f7/59bc0267a09b22fd?lnk=gst&q=oil+spark+plugs&rnum=2#59bc0267a09b22fd Is that the correct procedure to follow for an 01 Maxima? And is this something that I can do myself or should I take it to a shop? Thanks, Dave
