i have a catch can setup from the oil nipple under the fill tube on my tubo2 to the filler neck nipple. when i run the car at idle with the cap on there is smoke that comes out of my tail pipe. when i remove the cap no as much comes out. from the threads that i have read i guess its a bad oil seal in the turbo? if you need pics then i can give you pics of my catch can setup. should i run a vent line from my catch can so that exess pressure dosent build up?

 

bump

 

no u should replace ur turbo, cuz its fucked up
