Sparkplug ?

I have 2001 ss with only 24,000 miles,I changed the plugs and as I took out one spark plug I found it to be oil soaked.How bad is this?The others were normal looking.The car so far hasn't burned any oil I've checked very little if any.What should I do?

Most likely it is coming from the intake manifold. These LS1s are notorious for sucking in oil from the poorly designed PCV system. The oil ends up coating the inside of our intake manifolds and dripping down into the cylinders. The rearmost cylinders seem to collect the most oil.

I would highly recommend that all LS1 owners install an PCV oil catch-can to reduce the oil consumption inside the intake. Our sponsors AMW makes some nice ones, see here:
