If the car idles for a long time with no load, then I drive away it smokes like a forrest fire. After about 20 seconds of driving the smoke clears and will never return unless I sit idle for 5+ mins again. Seems like the turbo is leaking as it only happens with no load. Or maybe the PCV but I'm thinking turbo, it hasn't lived the easiest life. When the cars under load, no signs of smoke and I can redline up through 5th 140mph .49 knock, 0 ltft everythings great. I added a little oil last oci but the oil level hasn't dropped a bit since I changed it 2 weeks and 700 miles ago. Side note it's definitely not coolant and and coolant hasn't dropped any in 24 months and I check with a milimeter ruler.

I rarely notice this problem as I always take off less than a minute after starting the car and don't hit big traffic lights often so the car is usually under load. Time to upgrade turbo?

PCV valve maybe? You can take it out and shake it to see if its still clicking. If you want to change it anyway just to rule it out its a super cheap part and takes 5 minutes.

I think you have already upgraded studs and headgasket right? I would hatefor it to be the turbo but if it is it sure is time to upgrade!

I called dealership and they said the yellow speced one is on back order no ETA but they could get the discontinued red one that lists the civic along with accords and CR-V. I'm out of state this week but I have tools so maybe I'll just shake it and pick up a red one if it's bad. My friend also has one with 40k on his blown motor I might nab when I get home. Red vs yellow PCV linked below. Yellow one comes up when I enter the 19 si but red discontinued one should also work?
