Just ran across this over@ f150online.
"Also while running OASIS today on an 04 4.6 2v with a complaint of a startup rattle I ran across the latest SSM from FORD.21049 1997-2010 MULTIPLE VEHICLE - 4.6L/5.4L - ENGINE TICKING AND/OR RATTLE NOISE MULTIPLE VEHICLE LINES WITH 4.6L OR 5.4L 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). FOR VCT EQUIPPED ENGINES, INSPECT THE VCT VALVE BODY AND THE OIL PASSAGES UNDER THE FIRST CAM CAP. DAMAGE TO ENGINES CAUSED BY AFTERMARKET OIL FILTERS ARE NOT COVERED UNDER WARRANTY.EFFECTIVE DATE: 10/22/2009"
