Engine power loss and oil in a spark plug boot is caused by one of two things, either a cracked valve covor gasket that is letting oil seep into the boot at the top........or even worse a blown head gasket, i would sugguest a compression test to determine the problem

What are the effects of a spark plug not working?
A spark plug is used to ignite the fuel/air mixture inside the cylinder of an internal combustion engine. If the spark plug isn't working, the cylinder won't fire.
