Squeaking and knocking after oil change

  • 3.6L
  • 6 CYL
  • 4WD
  • 155,000 MILES
I know the timing chains were recalled and we have previously been dealing with engine codes relating to off-time problems. Just did an oil change, nothing out of the ordinary other than I only three to four quarts came out of the car, there is a slight valve cover leak. Now there is knocking, squeaking, and will not go over twenty mph. Did the oil change just completely do in the chains?
Do you
have the same problem?
