I had a mishimoto catch can which isnāt really suppose to be used with the KLM kit and turns out for some reason that was causing all the white smoke. Because literally as soon as I disconnected it, all smoke went away oddly. Now I get zero white smoke. Now I went ahead and bought the klm catch can lol
Well I ask only because I recently did PCV block off pins on mine with a KLM catch can and the top of my catch can smokes now (which is normal since there is no vacuum source to draw the blow by vapors)
I ended up re doing compression and got 149-150 psi with all cylinders. Must of not done cylinder 5 and 6 how I was suppose to the first time. But to be honest I donāt know whatās technically the normal psi for a 6 port to be at. All my cylinders are at 150 psi but Iāve seen people have as high as 220 psi across all cylinders. So makes me wonder if mines is low lol2020 2-port minimum compression is 131psi.
(I know OP mentioned his is a 6-port)
What is the second line off the catch can connected to CCV port?
I ended up getting an oil cap breather and ran a line from the catch can back to the intake plenum with a VTT one way check valve. It'll pull the vapor under vacuum/idle and under boost keep the check valve closed allowing the PCV system to vent as needed through the catch can breather and oil cap breather. Have not had a single issue or bit of smoke ever since.
When you blocked off your PCV with pins, do any of your new PCV vents or cans attach to a constant source of vacuum? For example, running the valve cover to a t-tap on the large barb at the front of the manifold. The car will smoke at idle if there is insufficient vacuum for the crank case after doing a PCV blockoff.
No I do not have anything running to that. Actually all the stock hoses and stuff are still connectedWhen you blocked off your PCV with pins, do any of your new PCV vents or cans attach to a constant source of vacuum?

My car has been doing this on and off for well over a year now. Some days I can drive the car all day without seeing any smoke what-so-ever, but then some days it will happen once or twice. My issue is that the little wafting of smoke only ever happens when coming to a stop and once I am completely stopped, it does not smoke while idling at all and does not smoke at all while driving or during WOT, only when coming to a complete stop. My car still seems to run and drive as if it were brand new.
im turbo swapped. EFR 8474. I was thinking maybe my turbo seals are toast but under boost (34psi) nothing turbo responds and hits like a freight, getting off the throttle after a pull nothing. But soon as I come to a stop itās smoking like a chimney for a good bit. If the light is a long red light itāll come to a stop. When I take off more smoke then nothing. Havenāt needed to add oil or coolant at all
Sounds exactly like my experience minus the "smokes like a chimney for a good bit part". My car will literally stop smoking like 2 seconds after I've completely stopped.
