Is it oil contamination?

Re: spark plugs?

Not sure how to tell. The engine is brand new with only like 100 miles on it even though it's been in the Blazer for many years as I have been working on it.

Re: spark plugs?

If it is that low miles the rings may not have seated. I'm guessing at it though, post a pic of a plug - someone will know.
