Just curious. Has anyone ever changed the Northstar timing chains and can it be done with the engine in the car?

They should last the life of the engine, so unless one breaks, don't worry about them!

I'm not worried about them, I just want to know if they can be changed while they're in the car or if the engine has to be yanked.

Never tried it in the car but can't see why you couldn't.

You can change them in the car if there was ever a need. It would not be the easiest thing to do. The damper, accessories and front cover would have to come off as well as the cam covers. From inside the wheel well on the right side you can access this stuff in the car. Inside the front cover, all you would have to do is to reset the cam chain tensioners, remove the cam sprockets and remove and reinstall the chains. It will be far easier if you get the front cover off and turn the crank until the sprockets are in time so you know what point you are working to and don't have to re-time things with the chains off.

As stated, the timing chains should never need replacement so, unless parts fall into the works and snap something the chains will last forever.

It's a bet between two mechanics. Nothing's being changed.
