i checked my spark plugs the other day and noticed there was a substantial ammout of oil in the 2nd plug from the right hand side of the engine (4 cylinder 94 accord), there was enough oilin the hole to coverhalfthe plug.I couldnt even see the nut at the bottom. is this an expensive fix? is my engine doomed now?

 

no, not a major repair, take the valve cover off and replace the "o" ring. Get yourself a helms manual or hayes or chilton, or go to the local library and get the info to change, You can alsoget onAutozone.com site, sign in for free, and navigate to repair of your car, many times there are pictures and instructions on how to. If you want to know cost of parts, Autozone.com has this too.
