Oil on spark plugs

Ugh! When changing my daughter’s plugs, I noticed light oil on a couple of the plug threads. I had a shop replace the seal tubes and valve gasket. Car ran smooth before and after this repair. It has 92K miles. Recently got a SES P0300 misfire read. Took it back to the shop (I trust this shop) and they diagnosed it as oil infiltration from a different location. I can’t remember the technical description but they say that the repair is mostly labor and could be up to $2,000! They only charged $200 for the Seal Tubes and Valve Gasket. They’ve worked on all our cars for many years. So when they are talking about $2000, I believe them and am a little freaked out.

Is this a common issue on Cubes? The misfire is only at cold starts. Will a bottle of Lucas cure this 🙂. Man!
