Installed new spark plugs (pics)
I installed new NGK OEM Honda spark plugs today on my 1990 Honda CRX Si today (original 283,679 kms)
Last ones were done exactly 20,000 km ago in 2012.
I noticed that they have slight oil on them (using 5w30 synthetic oil) (newer valve cover gasket and spark plug gaskets) and alot of carbon and the copper center electrode is unevenly worn.
see pics
Is this normal wear ?

Re: Installed new spark plugs (pics)
oil on plugs near leads, sparkplug seals may be bad.
more oil on plugs
Left one looks oily, note discoloring on porcelean right under the tip
far left White blistering, might be running lean (not enough gas)
These answers could of been easily found with a simple search btw.
