My 12’ 451 had this issue. Took it to the shop and they said it’s egr issue. Took it all apart and that wasn’t what it was. $149 and a 2 days worth of work gone. Ordered and pcv valve after watching your video and just got it installed this morning and works beautifully. I couldn’t find any all thread rod to make lowering bolt so I just took them all out and threaded them back in a few turns to lower the engine enough to get the air box out. Got it all reassembled and fired her up and burned off the smoke and good to go! Excellent video and tutorial.
I think I am having this exact same problem when I start up my car it has a big poof of white smoke and then it disappears and then smoke comes out like that in the video and I got no bubbles in coolant and my oil is burning/disappearing...
