NOTE: Hydraulic valve lifters are used; no valve adjustment is required. When valve and/or valve seat is machined, valve clearance is reduced and may cause improper valve operation. Different length push rods are available for correcting clearance. Valve lifter must be collapsed to check valve clearance. 1. With valve cover removed, position piston No. 1 at TDC of compression stroke. Completely collapse cylinder No. 1 intake valve lifter and hold valve lifter collapsed. Using feeler gauge, measure clearance between rocker arm and valve stem. 2. Clearance should be within specification. Refer to COLLAPSED VALVE LIFTER CLEARANCE table. Replace push rod, if necessary, to obtain correct clearance. 3. Position crankshaft as specified. See, in this article, VALVE CLEARANCE CHECKING SEQUENCE table, and check appropriate valves. Replace push rods if clearance is not within specification. 4. If push rod(s) is replaced, ensure corresponding cylinder piston is below TDC. It will be necessary to loosen or remove rocker arm to replace push rod. CAUTION: DO NOT operate or crank engine after installing push rod until valve lifter has leaked down to normal operating position. COLLAPSED VALVE LIFTER CLEARANCE

FORD: 2005 Mustang 2004-2005 F-150 2005 Expedition, F-250, F-350 This article supersedes TSB 05-15-8 to update the Service Procedure. ISSUE Some vehicles equipped with a 4.6L 3-valve or 5.4L 3-valve engine may exhibit a ticking and/or knocking noise after reaching normal operating temperature. The noise may be described as “ticks”, “taps”, “knocks”, or “thumps”. In some cases the noise may be a normal characteristic of these engines. In other cases the noise may require further investigation. Sorting out and defining the noise as reported by the customer is important to successfully diagnose and/or repair the condition. ACTION Before starting diagnosis, it is critical to determine the specific engine noise the customer is concerned with. The customer should be interviewed to get their detailed perception and description of the noise, and to determine if the noise occurs at idle or above idle speed, and if the engine is cold, hot, or both. Attempt to duplicate the noise, and determine the source of the symptom. Refer to the following Service Procedure to help determine the source of the noise and if a repair is needed.
