If you have rod bearings making noise then you will have metal shavings in your oil. Everytime I have had rod bearings go out on one of these cars it happens quick. Next time you change your oil filter the oil coming out of the engine and look for metal shavings. My guess is that your rod bearings are fine or the car would not run very long and you would lose oil pressure also. I have blown 3 motors because of rod bearings.
