Yeah I would definitely change it! The time has more effect than mileage on rubber most times. Thanks for watching 🤙

Thank you! The stud was ordered from the local Nissan dealer. Crank seal wasn't leaking, so I let it be.

No issues with it yet

The thing with all this is that the timing belt NEEDS to be installed at tdc with both lifter trays removed(becauuuuse this way the appropriate amount of tension is achieved.) Then go ahead and install lifter trays and use digital torque wrench and follow tightening procedure. These are steel bolts going into aluminum threads so be carefuls. But that would mean removing valve covers which means removing distributor not to mention upper plenum. Valve cover gaskets and new valve cover bolt seals while you're there. You might tear the valve cover breather hoses☠️. Find leaky vaccum or throttle body coolant hoses. Blow out spark plug holes PRIOR to removing them and clear all debris that falls in when you remove them and not notice. Then there's a chance you'll notice how you have naturally broken exhaust manifold studs/nuts. Something to address while your there. Get yellow zinc 30mm length 6x1.0 thread pitch bolt for the valve cover hardware. They come in 10mm heads and help instead or having iffy Philips screws that may or may not be tight because of the slip in the striped Phillip heads. Use orange permatex brand threadlock. If you remove the timing cover and check how much deflection at center between cam pulleys it might be floppier than sexy pasta. I like cars and the moves they make. 🏎️

I see what you mean at 7:20. I showed NO.1 at TDC just to give an example of the distributor. This was before I degree the cams / crank. Shortly after at 8:10 you'll see both cams and crank are in line with NO. 1 at TDC.

It will run off a tooth in either direction. It may have a dead spot in rpm or strange idle. A compression test will give you an idea of how off the cam timing may be. The marks on your pulleys and cover should all line up. The best way to check the belt is to count how many belt teeth are from each mark to the next. 40 teeth between the cam pulleys, 43 between the driver side cam and the crank pulley. Check it, turn motor over by hand, check it again. Hope that helps!

NA , took around 8 - 10 hrs to complete , that includes cleaning and painting the parts.
