Mechanic recommendations Lafayette

[Duck Butter]

Can anyone give me some good recommendations for mechanics in Lafayette? Vehicle is a 2007 Ford F-150


I have gone as far as I can with it. The check engine light came on a few months back and was coded as a misfire. Went to change the spark plug on that cylinder and the spark plug well was filled with engine oil. Cleaned it out and replaced spark plug ran fine for a few months until now. All the plug holes on the drivers side are full of oil. Pulled the valve cover off and changed the gasket thinking that may be the problem, but the valve covers are below the spark plug holes so it couldn't really be that. The area around the spark plug wells are all clean as can be so its not oil seeping into the holes from the top, has to be coming from elsewhere. Read where it could be valve seals or even piston rings. Just seems strange that its only on that one side? Thanks in advance
