Smoking 4.6L

[twetzel]

I have a problem with my motor, and I am trying to figure out exactly what before tearing into it. Here goes:

• 1994 T-Bird, 4.6L V8, 100k miles
• Daily driver all its life
• K&N filter, removed catalytic converters (had to replace an O2 sensor after this)
• Shortly after removing the cats it began to smoke, progressively worsening.
• An oily film built up aroung the exhaust tips and grew larger, now covering the entire tip.
• I have to add a quart (Penzoil) between oil changes (3k miles/3 months). The engine leaks no oil as far as I can tell. No warning lights are on (check engine, etc.).
• The smoke smells like oil sometimes, and I am not 100% sure of the color. I am afraid it is slightly blue, and it smells bad. It is definitely not coolant.
• The smoke is worst when it is hot outside and the engine is warmed up. Sometimes when I take off normally from a light, I can see a cloud of smoke behind me. It also lets out a puff sometimes when I start it up and the engine is already warm. I can usually smell it at a stoplight or when I pull into my driveway, even if I cannot see the smoke in my mirror.

My father has asked the mechanics at his shop (Davis-Moore, Wichita, KS) about any common problems with the 4.6L that would cause this behaviour, and they said no.
Any advice would be much appreciated. Maybe I should have bought a Mustang?
