Engine Mechanical problem
1991 Subaru Legacy 4 cyl All Wheel Drive Manual 180xxx miles
I have a 91 legacy that would burn white smoke when starting for the past year then after warming up the smoke would go away. After looking at the engine I could tell there was some oil seeping from above the engine into 1 first spark plug so every few months I would replace the spark plug. Well in the past day or so it started to run rough so I replaced the plug and wire and now ignition coil and its still running rough. After inspection the number 1 cylinder is not firing even after the replacment parts. I took out the plug after starting and its oil covered engine still runs rough please help.
