Frequently Asked Questions (FAQs)

1. What is the bearing clearance of a performance rod?

The bearing clearance for a performance rod is typically 0.001-inch of clearance for every one inch of crank journal diameter. For example, a small-block Chevy with a 2.200-inch rod journal would require a bearing clearance of 0.0022-inch.

2. Can an engine with a spun rod bearing be fixed?

If an engine has a spun rod bearing and is rebuildable, it can be fixed. This usually involves resurfacing the crank journal and potentially re-machining the main bore or big end rod bore, depending on the extent of the damage.

3. What happens if the rod bearing clearance is too much?

If the rod bearing clearance is too much, the spinning crank will cause the oil to be flung out from between the bearing and the crank journal. This can result in low oil pressure and potential engine damage.

4. How do I determine the size of rod bearings I need?

To determine the size of rod bearings you need, you will need to measure the inside diameter of the bearing using a dial bore gauge. Accurate measurements down to 0.0001-inch are recommended. It is important to use quality tools for accurate measurements.

5. Does replacing rod bearings fix rod knock?

If you hear rod knock, it is crucial to take immediate action and replace the rod bearings. Rod knock is a serious problem that will not resolve itself. Additionally, any other parts associated with the sound should be inspected and repaired. Delaying action may result in the need to replace the entire engine.

6. Does a spun bearing ruin the block?

A spun main bearing can cause damage to the main bore in the block, but it rarely leads to crank failure. However, a broken rod caused by a spun bearing can cause significant damage to the engine.
