Escort L4-116 1.9L SOHC HO (1989)
Valve Clearance: Adjustments
The 1.9L engine is equipped with an overhead camshaft and hydraulic lash adjuster. Valve stem to rocker arm clearance is measured with tappet
completely collapsed. Perform the following procedure when measuring valve tappet clearance:
1.
Rotate engine until piston of No. 1 cylinder is at TDC of compression stroke.
2.
Position suitable hydraulic lifter compressor tool onto rocker arm, then slowly apply pressure to bleed tappet. Continue to apply pressure until
lifter plunger bottoms. Hold tappet in this position and check clearance between rocker arm and valve stem tip using a suitable feeler gauge with
less than a 3/8 inch width. Collapsed tappet gap clearance should be .059-.194 inch on 1.9L/4-116 engines. If clearance is less than specified,
check for worn or damaged fulcrums, tappets or camshaft lobes.
3.
With No. 1 piston on TDC of compression stroke, check the following valves as outlined: Nos. 1 and 2 intake & No. 1 exhaust.
4.
Rotate crankshaft 180° from present position, then check the following valves: No. 3 intake & No. 3 exhaust.
5.
Rotate crankshaft 180° from present position, then check the following valves: No. 4 intake & Nos. 2 and 4 exhaust.
