had a used engine put in the car its a 16 valve EFI the motor makes a load rattling noise near the oil pan. and you can hear it from the top with the hood open. have driven it up the road and on the highway, it doesn't seem to have a loss of power when stepping on the accelerator. How could i access the problem?

Start by trying a higher octane gas to rule out pre-ingition.

If problem persists, you will have to remove oil pan and inspect rod and main bearings.
