Engine Mechanical 5.7l v8 - VIN [P] Chevrolet Camaro IV

ENGINE IDENTIFICATION

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

Engine can be identified by eighth character of Vehicle Identification Number (VIN) which is stamped on a metal pad, located near lower left corner of windshield. See ENGINE IDENTIFICATION CODES table. An "S" in tenth character of VIN indicates 1995 model year.

Engine can also be identified by a 3-character engine code (RPO code). See ENGINE IDENTIFICATION CODES table. This code may be stamped on engine, at flange where engine and transmission meet.

ENGINE IDENTIFICATION CODES

VALVE CLEARANCE ADJUSTMENT

Note. Engine is equipped with hydraulic valve lifters. Adjustment is required only if valve train has been disassembled.

Remove rocker arm covers. Rotate crankshaft until cylinder No. 1 is at TDC of compression stroke. Begin by adjusting exhaust valve of cylinder No. 1. See VALVE CLEARANCE ADJUSTMENT SEQUENCE table. While trying to rotate push rod with thumb and forefinger, loosen nut on rocker stud until push rod just starts to rotate. This is considered zero lash. Tighten nut 3/4 - 1 1/4 turns (this centers the lifter plunger).

VALVE CLEARANCE ADJUSTMENT SEQUENCE

GENERAL PRECAUTION

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

FUEL PRESSURE RELEASE

Disconnect negative battery cable. Loosen fuel tank filler cap. Connect Fuel Gauge (J-34730-1) to fuel pressure connection (wrap shop towel around fitting to avoid spillage). Install bleed hose. Turn gauge valve, and drain fuel into an appropriate container.

COOLING SYSTEM BLEEDING

Note. Care should be taken to prevent coolant from splashing onto the opti-spark distributor assembly. Place shop towels between water pump and distributor.

1. Open air bleed valve on thermostat housing (if equipped). With engine off, add coolant to radiator until solid stream of coolant flows from air bleed valve, then close bleed valve. Fill radiator to base of fill neck. Fill coolant recovery reservoir to full COLD mark. Leave coolant recovery reservoir cap off. With radiator pressure cap removed, run engine until normal operating temperature is reached (radiator inlet hose hot).

Add coolant to recovery reservoir until coolant level is about 1" (25 mm) above FULL COLD mark. Install coolant recovery reservoir cap. Check for leaks. Coolant level in recovery reservoir should be check after thermo-cycle has completed (full hot-to-full cold). Add coolant as necessary.

Valve Guides

Check and service guides before servicing valve and seat. Guide replacement information is not available from manufacturer. Valve guides may be reamed for installation of .003" (.08 mm), .015" (.38 mm) or .030" (.76 mm) oversize valves.

Valve Seat

Valve seat replacement information is not available from manufacturer. Follow instructions of tool manufacturer for servicing valve seats. If seats are serviced, service or replace valves.

Valves

Check valves before servicing. Replace valves as necessary. See VALVES & VALVE SPRINGS table under ENGINE SPECIFICATIONS. Valve face may be machined.

Valve Seat Correction Angles

If seat is too wide after grinding, use a 20-degree stone to lower or a 70-degree stone to raise seat.

Piston & Rod Assembly

1. Mark rod and rod cap with matching cylinder number. Before disassembling, mark piston-to-rod position for reassembly reference. Notch or dot on piston top should face front of engine. Piston pin is a press fit.
2. When measuring, ensure pin bore and piston pin are free of varnish and scuffing. If clearance between the piston and pin exceeds specification, replace the piston and pin as an assembly. See «PISTONS, PINS & RINGS»(/chevrolet/camaro/iv-1992-1998/remont/mechanical/#engine-mechanical-57l-v8-vin-p) table under ENGINE SPECIFICATIONS.

Fitting Pistons

Ensure notch or dot on piston top faces front of engine. Check pistons for wear and damage. Replace pistons as necessary. Check piston-to-cylinder bore clearance. If one cylinder needs to be bored, bore all cylinders to same oversize.

Piston Rings

Install marked side of ring toward top of piston. Top compression ring is chrome or molybdenum face. Second compression ring has a tapered face. Oil ring is a 3-piece type. Ensure end gaps are evenly spaced on piston. (Scheme 37)

Note. Rod and main bearings are available in .001" (.03 mm) and .002" (.05) undersize for oil clearance adjustment.

Rod Bearings

Ensure bearing cap bolt holes and mating surfaces are clean and dry. Use connecting rod stud protectors on rod cap bolts. Install inserts in connecting rod and cap. Lubricate bearings and crank pin. Install bearing cap. Tighten rod bearing cap bolts to specification. See TORQUE SPECIFICATIONS .

Crankshaft & Main Bearings

1. If bearing clearance is greater than specification, replace with undersized bearings and recheck bearing clearance using Plastigage. See «CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS»(/chevrolet/camaro/iv-1992-1998/remont/mechanical/#engine-mechanical-57l-v8-vin-p) table under ENGINE SPECIFICATIONS.
2. Tighten the main bearing caps finger tight. Pry the crankshaft rearward and then forward to align the rear main bearing thrust surfaces. Retighten the main bearing caps to specification. See «TORQUE SPECIFICATIONS»(/chevrolet/camaro/iv-1992-1998/remont/mechanical/#engine-mechanical-57l-v8-vin-p__torque-specifications) .

Thrust Bearing

Check crankshaft end play by forcing the crankshaft to the extreme forward position. Measure end play at the front of the rear main bearing using a feeler gauge. If end play is not within specification, replace thrust bearing and/or crankshaft. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS.

Cylinder Block

Check cylinder bore for wear, taper, out-of-round and piston fit. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS. Cylinders with less than .005" (.13 mm) wear or taper can be honed. Cylinders with more than .005" (.13 mm) wear or taper should be bored to smallest oversize piston which will permit complete resurfacing of all cylinders.

Scheme 37

ENGINE LUBRICATION SYSTEM

A gear-type oil pump provides pressurized lubrication through the full-flow oil filter. Oil pump is bolted to bottom of cylinder block, inside oil pan. Oil pump is driven (through intermediate shaft) by a gear on rear end of camshaft.

Crankcase Capacity

Crankcase capacity is 4 qts. (3.8L) without oil filter change or 5 qts. (4.7L) with oil filter change.

Oil Pressure

With engine at normal operating temperature, oil pressure should be at least 6 psi (0.4 kg/cm 2 ) at 1000 RPM, 18 psi (1.3 kg/cm 2 ) at 2000 RPM and 24 psi (1.7 kg/cm 2 ) at 4000 RPM.
