Master Ford Tech
Some 1997-2008 E150/f150, 1997-2008 Crown Vic./grand Marquis/town Car, 1997-2009 Mustang Gt, 1997-1998 T-bird/cougar And 2002-2008 Explorer/mountaineer With 4.6l Engine May Experience An Engine Ticking Or Rattle Noise That Sounds Like A Stuck Tappet (hla). This May Be Due To The Deterioration Of An Aftermarket Oil Filter. Vehicles With This Condition Have Low Oil Pressure At One Cylinder Head Only, While Main Pressures Are Normal. Dislodged Material From The Aftermarket Oil Filter Blocks The Cam Cap Oil Passage, Either At Cylinder #4 (right Bank Rear) Or Cylinder #5 (left Bank Front). Ford Recommends The Use Of Ford Approved Filters Only. Damage To Engines Caused By Aftermarket Oil Filters Are Not Covered Under Warranty
