A spun rod bearing would last a few days... or more like hours.... at best! NOT months!
Replace the tensioner.... and the chain while your in there.... and call it a day!

You probably have spun bearings.

Spun bearing = tick every rotation of the crank.
Bad tentioner = tick every other rotation

RE: Timing chain tensioner or what???
Wow.
I've never heard of anyone ever spinning ALL of their bearings, not to mantion both rods and mains. That's tough to believe unless you just ran it without oil and got REALLY lucky that it didn't lock up on you completely before they all spun.
ONE spun rod bearing can freeze a motor if things happen the right way. A spun rod bearing is usually a high pitch squeak sound once per revolution. It will get much worse with engine load. It will not last long at allbefore you lose most of your oil pressure.
if you were to spin ALL of your bearings at once, the engine would lock up in 99.99999999% of cases, would have no oil pressure andwould sound like a freight train. If you could drive it like this, you'd probably end up throwing rods due to them binding together or breaking the crank in two from the weird loads and harmonics.
Bearing material will also adhere with the crank journals and make quite a mess and a difficult repair if it's driven much with a spun bearing. Spun bearings are nothing to sneeze at.
