Hi again. Quick update apparently the truck came fitted with blank egr from previous owner. Now the big stuff I decided to take the truck for a long run and take the familly our for the day but instead after driven 8miles I have broke down the tapping noise was getting louder and eventually there was now power to move the truck. And there is a bit of oil drip on the floor and now there is white smoke come when you crank it but still undrivable till this point. Am so lost now.
