Guess it's time to get the Pathfinder running again. It's been sitting for a few years but still cranks. But when it cranks the engine starts smoking. I can typical work my way through any repair with good instructions. I have access to a garage and tools, so where do I start? I'm guessing the valve gaskets need replacing. I do have the owners manuals. What else is going to have to be replaced? Thanks in advance for any and all help.
