Exhaust in the oil on 1994 Ford Escort

My 95 escort seems to be running rich. It exmits alot of bluish smoke out of the exhaust. And it runs rough at a idle, but at a higher rpm, it smooths out. It has no power when going up a hill. And it has exhaust coming out of the engine when i remove the oil fill cap I have cleaned the air intake and replaced the fuel filter, air filter. It does not seem to be the plug or plug wires. for they are new. please help

It sounds like the piston rings are worn out. Excessive blow by is causing the exhaust out of the fill cap, This loss of compression will also account for the loss of power.
