TAPPING NOISE ON MY 2006 JEEP WRANGLER UNLIMITED
I PURCHASED A 4.9 STROKER ENGINE FOR MY JEEP WRANGLER UNLIMITED. THE WRIST PIN CAMEON NUMBER 6 CYLINDER OUT SO WE SENT IT BACK. THEY SENT US ANOTHER ONE PROBABLY THE SAME ONE THAT THEY FIXED, THERE IS A SORT OF TAPPING OR CLICKING NOISE THAT IS LOUD WHEN IT IS FIRST STARTED GETS LOUDER AFTER A MINUTE OR TWO AND THEN GETS A LITTLE LESS NOISEY WHEN IT WARMS UP.
DOES ANYONE KNOW WHAT THIS COULD BE
