Nissan Pathfinder (VQ40DE) Timing Chain Replacement

This is how to replace all 3 timing chains, guides, and tensioners on a Nissan VQ40DE engine. This one happens to be in a Pathfinder but process is the same for any VQ40DE. This is not a quick or cheap repair but is thousands of dollars cheaper to do at home rather than taking it to a repair shop. Just make sure your mechanical skills are up to par for this level of repair before starting. I would put this at a 6-6.5 out of 10 on the difficulty scale.

I’m not a car guy, but I’m glad to see you back on the air. That means you guys are OK.😁✌️

With that slack on the right side of the chain, did the chain jump a tooth or did you hold it to prevent movement?
