What do we know about my atrai engine, it's a 5 speed 4wd a/c turbo van. I have been hearing some valve clatter at lower rpms and I am about to change the (likely stock) spark plugs to which I think I found the correct ones sitting on the shelf. Maybe adjust the valves? Does anyone know the specs for this engine?
