Crank bearings - safe mileage
Hello,
I have rebuild my engine some time ago in R33 GTR and done already 60 000km putting new nominal crankshaft and ACl bearings. I was visiting lately one drift shop with lots of experience in Rb26 engines. They say its already time to change the bearings cuz they like to spun. True or not true and when to change them? I am using my car for daily driving and 2-3 times track days a year. Can i go up to 100 000km without any fears or should i change them now.?
