Low ICP? and P1211 code

[bamboo]

ok I have a interesting factor to add im not 100% sure but..

Changing my fuel filter tonight, Lights beaming, so Start it up to check for leaks.. Nice looks clean every thing is good, But then I notice some smoke by the downpipe, passenger side valve cover appears to be cracked/leaking

Dubya Tee eff does that mean? Could that be my low boost, and lack of oil pressure ? definitely leaking oil, Like a blind man I missed it

I feel stupid, and Ticked, I Never had this issue before my injector swap, This isn't the first time I changed my filter at night..
So tomorrow ill get the degreaser and a flashlight and find out if its really cracked or what.. But I took a video with the lights if any body is interested

One thing after another
