Volvo 1988 240DL.170000+. When I picked up car noticed exhaust leak after having cat replaced. Ignored it, til noise didn't go away. Noticed flange gasket shot, decided to replace noticed 2 nut missing and the cat was installed backwards. What type of damage can this cause the engine? Am taking back to shop that repaired today. Please help!
