No chance to jet wash. Connected to computer and found injectors are working as should but egr isn't. Can't find source of leak but oil isn't milking nor is coolant level dropping. There is still White/grey smoke from exhaust when accelerating only uphill? Fine on flat ground unless really pushing. Is it worth putting stop leaks into oil and coolant anyway? Or could this be turbo issue? Being told fuel mix may not be correct but it may be oil combustion.
