so i had about 2-5 k on my v6 with out a catch can, some time later, i installed a catch can,,but i never looked into the Cold air tube going into throttle body. This oil change i took out approx 1/2-3/4 inch of old oil, Still not taking the cold air tube apart. This evening i installed a ported TB, and then i noticed it...some OLD oil in curved part of the tube that was apparently dried up from BEFORE i put in catch can. How do i deduce this?, is that there was NO new wet oil in Tube nor inside TB..so in my un-scientific research,i think the catch can is doing its job.......
i will keep and eye on this and report back sometime..
after popcorn..
