Cylinders are: # 1- Pass front, 2 Driver front, 3 Pass center, 4 driver center, 5 Pass rear, 6 driver rear.
So, you so far have oil in 2,4 & 6 plugs. That sucks.
When I changed my plugs at135Kish miles, I only found oil in 6. Haven`t done anything about it and probably won`t unless I experience a miss-fire.

I'll RTV both VC this weekend.
mine is 06 with 49K miles on it!!!! WTH? i don't even drive hard with my car!
I found little oil on plugs but the coilpacks are dry, instead I wait and might get worst and end up replacing coilpacks, i'll RVT VC now before too late
