If there is anything different between them you will see it. oil coating - wet?



1-3-7 have a slight discoloration and a slight black residue
5 has no discoloration or residue

2-4-6-8 are discolored and have a black residue on them including on the threads.

They were snugged up but not super tightened when I put them in originally.

If there was oil on the plug, wouldn't it blow blue smoke and not the white smoke I experienced?

any help there?
