Me and a bunch of my buddies got together to put my new mishimoto downpipe in on my 2016 FiST and after finishing the car was running fine. Then while driving it began to smoke pretty bad. After a few miles I parked and saw a major oil leak. I had a few codes pop up related to the camshafts. Had no boost pressure then eventually when trying to get home I went into limp mode (Had to get towed the rest of the way because it was running so badly). Any ideas what this could be before I starting looking at everything. Would like to get a pinpoint on what it could be specifically. Thank you.
