I have searched alot the past couple weeks and had a couple questions. In searching and in answers to previous questions I was told that the acceptable tolerance for rod bearings is 0.001"-0.003." I did also find a thread that gave a torque measurement for the connecting rod nuts, 33 lbs (Is this torque measurement correct?).
I have the oil pan off and below are the measurements from the rod bearings, starting in the front and moving to the rear
FRONT
1. 0.001"
2. 0.0015"
3. 0.002" s
4. 0.001" s
5. 0.001" s
6. 0.0015"
REAR
bearings marked 3, 4, and 5, had a noticeable scoring. I could feel depressions on the corresponding crank journals for those bearings.
With the affected journals I believe that simply replacing the bearings will only get me a little more time. The affected journals will cause quick failure in the bearings, right?
My oil pressure before beginning was not low but there was a knock I am attempting to correct. It sounded like it was in the bottom end, in the middle of the block. Could the scored bearings and affected journals be the cause a knock? And if so would replacing the bearings get rid of knock at least in the short term?
I won't get back to this thread till sometime tomorrow afternoon, I'm not a morning person especially on a Saturday, but thank you in advance for any input.
