Reading Plugs?

[TravisAZ]

Changed the plugs in my 8.1 this weekend.

 

Plugs 1 & 3 had dry, rusty threads.

 

The other 6 had oily threads top to bottom.

 

I can take pics and upload if needed. I believe these were the original Densos with ~110k on them.

 

Thoughts?

rust seems normal t be, i'm too lazy to go find the repair guide...oil indicates blow by or worn rings and or scratched cylinder walls if i remeber right
