    oil on 3 plugs

    99 VX 3.5 v-6 oil on three plugs, heavy GREY/ WHITE smoke out of tail pipe, pulled all 6 plugs 3 on passenger side fouled with oil, drivers side OK, compression checked all OK, leak down test all OK, pvc valve, hoses all OK, vaccum hoses all OK, ECG checked OK, EGC tube gummed a little but clear, any ideas how all three plugs on one side can get fouled at the same time?? Thanks, eyepatch

    do you have any knocking noises coming from your engine? if your PCV valve is sticking you would get increased pressure, not sure exactly why it would only go to one side but that could cause the oil to blow by the piston rings right? (im just guessing, i have a general idea of how everything works but dont know the details of it)
