Life span of a VQ37?

I know the plugs are supposed to be good for like 100K or something asstronomical. It still might not be a bad idea to change them now. And here's why. I had a 2005 Frontier that was running like a$$ right around 70K. Figured I change out the plugs and give it a good tune up. When I pulled the wire off the #6 plug, the head was full of oil thus covering the top of the plug and wire boot in dino piss.

I googled the find and surprisingly enough, it is quite common among Nissans in general. A lot of hits on Frontiers and Maximas. Sure, some go forever with no issues but it was common enough to be found on various forums. If I recall, the fix was to replace the seal on the intake plenum but it was just short of ripping the top end of the motor apart on the truck. So I cleaned it out, changed the plugs, and ran it to the dealer to trade in. (Another reason why I never buy used).

Long story short, there is a guy on here with 100K and no issues. Not a lot of folks are racking up crazy miles just yet, so who knows what quirks might surface when more of these motors get higher miles.
