Ford Escape: Engine / General Procedures - Valve Clearance Adjustment
Special Tool(s) /
General Equipment
Check
-
Refer to: Valve Cover (303-01C Engine, Removal and Installation).
-
NOTE:
Turn the engine clockwise only, and only use the crankshaft bolt.
NOTE:
Before removing the camshafts, measure the
clearance of each valve at base circle, with the lobe pointed away from
the tappet. Failure to measure all clearances prior to removing the
camshafts will necessitate repeated removal and installation and wasted
labor time.
Use a feeler gauge to measure the clearance of each valve and record its location.
Use the General Equipment: Feeler Gauge
-
NOTE:
The number on the valve tappet only reflects the
digits that follow the decimal. For example, a tappet with the number
0.650 has the thickness of 3.650 mm.
NOTE:
The nominal clearance is:
-
intake: 0.25 mm (0.0098 in)
-
exhaust: 0.30 mm (0.0118 in)
NOTE:
The acceptable clearances after being fully installed are:
-
intake: 0.23-0.28 mm (0.009-0.011 in)
-
exhaust: 0.27-0.33 mm (0.010-0.013 in)
Select the closest tappet size to the ideal tappet thickness available and mark the installation location.
-
NOTE:
Select tappets using this formula: tappet thickness =
measured clearance + the existing tappet thickness - nominal clearance.
If any tappets do not measure within specifications, install new tappets in these locations.
