Knocking sound..
GUYS I JUST HAD TO REPLACE MY CAM PHASERS AND A FEW OTHER THINGS DURING THE PROCESS BUT WHAT I DONT GET IS THAT EVERY PERSON WHO HAS HAD CAM PHASER PROBLEMS WITH THE TRUCK HAS HAD AT LEAST 60000 MILES ON THERE VEHICLE MINE HAS 23481 I CANT BELIEVE THAT THESE WOULD GO OUT SO SOON, BY THE WAY IT COST ME NOTHING TO REPLACE EVERYTHING BUT TO MY AFTERMARKET WARRANTY IT COST AROUND 2000 BUCKS. I KNOW ALOT OF OTHER PEOPLE HAVE BEEN HAVING THE SAME PROBLEM WITH THERES JUST WANTED TO SHARE WHAT I HAVE HAD TO GO THROUGH, THANKS! BY THE WAY SHE IS STILL IN THE SHOP WHICH REALLY SUCKS! BUT I GET HER OUT TODAY!!

5w20 is the recommended grade.
There seem to be no power loss issues related to the knock. I cant tell any difference in drive ability. But the knock is very obvious. But like i stated before, for only around 15 seconds. As far as the oil issue.. i believe my manual states to use 5w30. And I will be switching to motor craft filters on the next oil change. But im still gonna stay away from synthetics with my mileage..
Thanks everyone
Thanks everyone






Down south where it's hot most of the year 5w30 works perfect.
