Well, the plot thickens! So if the misfire started right after you did the valve seal job, that tells us something. Either something you did wrong caused the misfire, or it was just a coincidence. As for me, I'm not a big believer in coincidences.
For starters, I'd look all the way around the valve covers very carefully for any signs of an oil leak. You'll need a mirror for the back ends. I'd also pull all the coilpacks and shine a light into the tubes to see if any oil is in there.
