OK, made a catch and it seemed to help with oil getting burnt as it seemed to be getting worse before the catch can was added. But, like before when in 3rd or 4th, if I'm say cruising in 3rd at 35-40 MPH, and letting it decelerate in gear, then accelerate, then back to decelerating, I get a fairly noticeable cloud of smoke for a few seconds then it clears. It'll do it in 3rd and 4th only as described above (never had it do it in 5th and doesn't seem to do it in 2nd). If keeping a steady speed in 3rd, 4th, or any gear for that matter, it's fine and doesn't smoke. Only during that narrow window of slowing down in a gear then cruising then slowing down again will it consistently recur. No oil getting past the catch can either. What could it be? Still running the 5w30 as the oil is still fresh, but I'd have to think it'd be smoking all the time if the oil was the culprit, but maybe I'm mistaken. So long as I don't hold 3rd or 4th while slowing down a lot like in stop and go traffic it's not an issue. But if something more serious IS failing, I'd like to figure it out before it's a catastrophic failure. I can't be the only person who's had this happen.
