VALVE CLEARANCE ADJUSTMENT

Hydraulic valve lifters are used. No valve adjustment is required.

TROUBLE SHOOTING

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

REMOVAL & INSTALLATION

CAUTIONWhen battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

Note. For reassembly reference, label all electrical connectors, vacuum hoses and fuel lines before removal. Also place mating marks on engine hood and other major assemblies before removal.

FUEL PRESSURE RELEASE

Disconnect negative battery cable. Loosen fuel tank filler cap. Connect Fuel Pressure Gauge (J-34730-1) to fuel line fitting (wrap shop towel around fitting to absorb leakage). Place gauge bleed hose into container. Open bleed valve to release pressure.

Except "W" Body

  1. Fill radiator to base of filler neck. Start engine. Place A/C-heater control in any position except MAX. Select highest temperature setting. Idle engine until lower radiator hose is hot.
  2. Increase engine speed to 3000 RPM and then back to idle. Do this 5 times to expel any air trapped in system. Fill radiator as necessary. Install radiator cap. Allow engine to cool. Fill coolant recovery reservoir as necessary.

"W" Body

Open air bleed valve on thermostat housing. Fill radiator until coolant level is even with filler neck and no air bubbles are coming out of air bleed valve. Close air bleed valve. Install radiator cap. Fill coolant reservoir. Warm engine. Allow engine to cool. Fill radiator and coolant reservoir.

Turn wheels from side to side at least 20 times, but DO NOT touch steering stops. Add fluid as necessary to maintain level at FULL COLD mark.
  2. Start engine. With engine idling, check fluid level. Add fluid as necessary to bring fluid level to FULL COLD mark. Return wheels to center position. Lower vehicle. Continue to run engine for 2 to 3 minutes to raise temperature of fluid and eliminate trapped air. Turn steering wheel in both directions.
  3. Road test vehicle. Check for leaks. Ensure fluid level is at FULL HOT mark when fluid is stabilized at operating temperature.

OVERHAUL

Note. For repair procedures not covered in this article, see ENGINE OVERHAUL PROCEDURES article in GENERAL INFORMATION.

  1. Inspect cylinder head for warpage at deck and manifold surfaces. Resurface cylinder head if warpage exceeds specification. See «CYLINDER HEAD»(/chevrolet/camaro/iv-1998-2002/remont/mechanical/#engine-mechanical-38l-v6-vin-k) table under ENGINE SPECIFICATIONS.
  2. After resurfacing, use a depth micrometer to measure distance from deck surface to 3 cast pads. (Scheme 21) Replace cylinder head if dimension is less than.044" (1.12 mm). New cylinder head dimension should be.054-.066" (1.37-1.68 mm).

Valve Seats

No replacement procedure is given by manufacturer.

Valve Guides

If valve stem oil clearance is not within specification, ream valve guides for oversize valve stem. See CYLINDER HEAD table under ENGINE SPECIFICATIONS.

Valve Seat Correction Angles

After grinding, if seat width is too wide, use 20-degree or 70-degree stone to reduce seat width. A 20-degree stone will lower seat. A 70-degree stone will raise seat.

Valve Spring Installed Height

  1. Install valve, valve retainer and keepers. Pull upward on valve, and measure height from top of spring seat to spring side of valve retainer. see scheme 22
  2. Ensure spring installed height is within specification. See «VALVES & VALVE SPRINGS»(/chevrolet/camaro/iv-1998-2002/remont/mechanical/#engine-mechanical-38l-v6-vin-k) table under ENGINE SPECIFICATIONS. If measurement exceeds specification, add shims under valve spring to obtain correct height.

Valve Stem Height

With valve installed in cylinder head (closed position), use steel ruler to measure distance from spring seat to valve tip. Distance should be 1.935-1.975" (49.15-50.17 mm).

Valve Stem Oil Seals

Oversize valve stem oil seals are used for valves with oversize stems. Intake and exhaust valve stem oil seals are different. Install oil seal according to part number and package instructions.

Scheme 18

Scheme 18: Valve Stem Oil Seals

Scheme 19

Scheme 19

Cylinder Block

Using feeler gauge and straightedge, inspect deck surface for warpage. Replace cylinder block if more than .010" (.25 mm) material is removed from deck surface.

Cylinder Block Flange Runout

  1. With engine removed and crankshaft installed, measure cylinder block flange runout. Mount dial indicator gauge plate flat against crankshaft flange. Place dial indicator stem on lower left transmission bolt boss (flat area around bolt hole). Adjust dial indicator to zero.
  2. Observe and record readings obtained on all bolt hole bosses. Measurements should not vary more than .010" (.25 mm). If readings exceed specification, check crankshaft flange runout. See «CRANKSHAFT FLANGE RUNOUT»(/chevrolet/camaro/iv-1998-2002/remont/mechanical/#engine-mechanical-38l-v6-vin-k__crankshaft-flange-runout) .

Piston Ring Installation

Install piston rings with identification mark toward top of piston, and ring gaps properly spaced. see scheme 23

Piston & Rod Assembly

Piston can be installed on connecting rod in either direction. Install piston and connecting rod onto crankshaft, with arrow on top of piston and/or ridge(s) on bottom of pin boss facing toward front of engine.

Fitting Pistons

Note. DO NOT machine oversize pistons, or engine balance will be affected.

Piston diameter should be measured 1.73" (44 mm) from top of piston.

Crankshaft & Main Bearings

  1. Main bearing caps are a press fit. All main caps incorporate side bolts except the rear. Remove side bolts. Remove main cap bolts. Using Slide Hammer (J 6125-B) and Main Bearing Cap Puller (J 41348), carefully remove caps for service. Install main bearings and main caps. Hand tighten main bearing cap bolts.
  2. Tighten main bearing cap bolts to 52 ft. lbs. (70 N.m) to fully seat crankshaft. Loosen main bearing cap bolts 360 degrees. Tighten bolts to specifications. See «TORQUE SPECIFICATIONS»(/chevrolet/camaro/iv-1998-2002/remont/mechanical/#engine-mechanical-38l-v6-vin-k__torque-specifications) . Using wooden mallet, carefully tap crankshaft forward and then backward to seat thrust bearing.

Rod Bearings

  1. Ensure bearing cap bolt holes and mating surfaces are clean and dry. Use connecting rod stud protector on rod cap bolts. Install bearing inserts in connecting rod and cap. Lubricate bearings and crank pin.
  2. Replace both upper and lower bearings as a set. Install bearing cap. Tighten NEW rod bearing cap bolts to 20 ft. lbs. (27 N.m). Tighten bolts an additional 50 degrees using Torque Angle Meter (J 36660).

Crankshaft Flange Runout

  1. With engine removed and crankshaft installed, or with crankshaft mounted on "V" blocks, measure crankshaft flange runout. Mount dial indicator and place dial indicator stem on crankshaft flange. Adjust dial indicator to zero.
  2. Mark reference point on crankshaft flange. Ensure crankshaft is thrust forward so end float will not affect readings. Turn crankshaft 360 degrees.
  3. Observe and record readings. Reading should not vary more than .002" (.05 mm). Replace crankshaft if runout exceeds specification.

Scheme 20

Scheme 20

LUBRICATION SYSTEM

The crankshaft driven, gear-type oil pump provides pressurized lubrication to the main gallery. see scheme 24 Oil pump and pressure regulator valve are located in front cover.

Crankcase Capacity

Engine oil capacity is approximately 4 qts. (3.7L) without filter change. After changing filter, recheck oil level and add oil as necessary.

Normal Oil Pressure

With engine at normal operating temperature, oil pressure (with 5W-30 or 10W-30 engine oil) should be 60 psi (4.2 kg/cm 2 ) at 1850 RPM.

Scheme 21

Scheme 21: Normal Oil Pressure

Removal & Disassembly

Remove front cover. See FRONT COVER under REMOVAL & INSTALLATION. Remove oil filter adapter, gasket, pressure regulator and valve from front cover. Remove pump cover bolts, cover and gears from front cover.

  1. Inspect components for damage. Measure gear end clearance. Measure housing gear pocket depth and diameter. Measure tip clearance between gears. Measure outer gear-to-housing clearance.
  2. Check clearance between pressure regulator valve and bore. Replace components or pump assembly if measurements are not within specification. See «OIL PUMP SPECIFICATIONS»(/chevrolet/camaro/iv-1998-2002/remont/mechanical/#engine-mechanical-38l-v6-vin-k) table.

Reassembly & Installation

To reassemble, reverse disassembly procedure. Lubricate gears, and fill cavities with petroleum jelly. Install pump cover. To install, reverse removal procedure. Tighten bolts to specification. See TORQUE SPECIFICATIONS .
