Does rod knock affect oil pressure?

The cause of a rod knock is usually due to a spun rod bearing (could also just be a worn out bearing over time, but much less common). If the bearing spins inside its home in the large end of the connecting rod, oil pressure will first go up, due to less flow of oil where there normally would be.
