Knocking question

Hey guys! It has been a while since I posted a question, because I fear the answer... I changed the oil last time to Rotella T as I have read much about it on this site. I was driving in July on a very hot day and the car began to knock about one block from my home. I parked the car and haven't started it since. The car was not overheating and it had normal oil pressure as far as the dash gauge showed. Anyone have any thoughts?? :(
