Purchased my 07 in august 2014 with 70k miles. November 24, 2014 was leaving thanksgiving dinner when there was a call at the fire house.... noticed knocking sound upon arrival. great. spun a barring. replaced engine in december. its now february jeep has been running perfectly. until yesterday... knocking is back. This time though, the knocking is not a bad/loud and does not seem to be loosing any power. We had changed the oil at 600 miles just like it said to... about 500 miles in after that added .5 qrt of oil bc noticed it was low... day later it was low again... added whole qrt. No signs of leaking anywhere.

I haven't even had the vehicle for a year yet... sigh...

Any suggestions?
