2.2 DTI starts after 1-2 days after 10-15 min. What now??

Hello @all 2,2 DTI only starts after 1-2 days after 10-15 min. What now?? Traverse seal and oil leak pipes are new ( Opel made.) Car stutters and shakes up. After that mega smoke. No cooling water consumption. I once opened the oil cover with warm engine but neither foaming nor excessive pressure. After that he jumps back problemlessly but when I leave the car standing for 1 day (straight level) the organ egg starts again. (battery new) Thanks for the tips. Dsl-OLi
