a. Yes; repair the exhaust leaks. Verify repair.b. No; Go to step 17.

17. Remove and inspect the EGR hot pipe, EGR crossover tube and EGR mixer pipe.Refer to section "Removal of the Exhaust Gas Recirculation Hot Pipe".Refer to section "Removal of the Exhaust Gas Recirculation Crossover Tube".Refer to section "Removal of the Mixer Pipe".Are there any restrictions present?
