Help with old spark plugs




I changed my spark plugs and these are #3 & 4 … any idea what the oil may mean on the spark plug?

Impossible on 2007-2008 US market Fit due to design
Spark plug wells are not interfering with valve cover (unlike on Acoord or CRV)
Most likely busted valve stem seals (oil is sucked in during intake stroke, then squeezed past the threads during compression stroke.
