Engine - 3.0L V6: Diagnosis Ford Windstar I

TROUBLE SHOOTING

Note. To trouble shoot mechanical engine components, see appropriate table in TROUBLE SHOOTING - BASIC PROCEDURES article in GENERAL INFORMATION.

Inspection (All Models)

Clean head gasket mating surfaces. Clean carbon from combustion chambers. Check cylinder head for cracks, burrs, nicks and warpage. DO NOT machine more than .010" (.25 mm) from original cylinder head surface to correct warpage. Replace cylinder head as necessary. See CYLINDER HEAD table under ENGINE SPECIFICATIONS.

Inspection

1. Remove timing chain cover. See «TIMING CHAIN COVER»(ref-1331-S16479587252000031300000). Turn crankshaft clockwise until camshaft sprocket and crankshaft sprocket timing marks are aligned. (Схема №7) Mark top link on timing chain.
2. Using an assistant, apply 15 ft. lbs. (20 N.m) of torque using torque wrench in clockwise direction. Place a machinist's scale above timing chain, and note location of marked link on scale. Apply 15 ft. lbs. (20 N.m) of torque in counterclockwise direction while measuring marked link movement. If movement exceeds.12" (3.175 mm), replace timing chain and sprockets.

Inspect journal diameter, lobe lift, oil clearance and runout. Replace camshaft if not within specification. See CAMSHAFT table under ENGINE SPECIFICATIONS.

Inspect components for damage. Measure rotor end clearance, drive shaft-to-housing clearance and idler gear-to-driver gear clearance. Check clearance between pressure relief valve and bore. Measure relief valve tension. Replace oil pump assembly if measurements are not within specification. See OIL PUMP SPECIFICATIONS table.
