so gone through a world of pain with this car.. we bought it second hand turned into a car that needed a lot of TLC .. following things were changed , two injectors , low pressure diesel sender, high pressure fuel pump... now the car drives again but everytime I get out of the car I look at the sud covered tail pipe and I'm wondering am I looking at something else that is to go boom in the very near future.. ? anyone else with some experience can tell me what potentially the symptoms are
