Intermittent smoke at cruise

[89Shotyme]

noticed after installing catless DPs little smoke behind me once in a while. Pulled IC pipe off and had about 1/4" of oil on the engine dipstick down inside the IC. Sucked it out and cleaned off the MAP sensor on the tube. What's everyone's thoughts on this and what are people doing? Catch can I know is a good idea. Car runs and drives fine other then I think I might hear spark knock once in a while with my 93 tune.

Mainly notice it after stoped for a while and take off. Very intermittent.

Oil and coolant levels ok?

Yeah all is well. Talked with livernois and they told me that this is quite normal with direct injected motors when you delete all the cats. I added the catch cans and haven't seen much since. Waiting for the intercooler to clean out now I sucked a little bit of oil from it.
