65k on my 2.8 only dd. Plugs had 20k on them. All good till I changed #8 (passenger rear) and found the electrode fouled in oil. I will do a leak down test tomorrow, but wondering is this catastrophic? Car runs great, no blue smoke or oil consumption. Thanks.

The pic didn't work for me but are you positive it's oil? Because if it is fouled it will have a black gas like substance on it. Everyone of my plugs looked like that after I started it with a new fuel system. I don't think your motor is bad because I would think if it is oil on the plug then it would HAVE to be smoking some.

Just did a leak down test results as follows:
#1 160
#2 185
#3 150
#4 175
#5 170
#6 180
#7 175
#8 175

It didn't smell like gas and was black. I appreciate the input. Could this be a pvc issue by chance? I don't have a check engine light, and as stated, car runs great.

I'd say just change the plugs and run it for a little while (drive around for a while just like you usually do) then pull the plug out again when she cools. I'm pretty sure it'll be fine. I think you just fouled a plug buddy. You won't be able to smell gas either because it's partially burnt.
