I found some oil on the "Y shaped air duct'' that connects from the intake to the manifold there was oil on the outside. I been looking around on the internet but cant find a real reason that fits my problem. Also occassionally when picking up speed in 3rd gear over 4k rmp it will start jolting and it feel like its getting missing pockets of air into the manifold in uneven amounts making it jump forward n back. that doesent happen often but still bothering me. Any thoughts? It doesent feel like there is a second pull from my other turbo either. Bothering me. So any thoughts thanks!
