Engine Rebuilding Course

Lesson 1 • Tools and Equipment Familiarization

Introduces hand tools, power tools, and precision measuring instruments used in engine rebuilding. Correct tool selection prevents damage and ensures accurate measurements.

Lesson 2 • Service Documentation and Technical Manuals

Teaches students to locate and interpret OEM service manuals, torque specs, and clearance tables. Accurate documentation use is essential for every rebuild decision.

Lesson 3 • Major Engine Systems Identification

Identifies lubrication, cooling, fuel, and ignition systems and their interdependencies. Builds the system-level thinking required for accurate diagnosis and rebuild planning.

Lesson 4 • Internal Combustion Engine Overview

Covers the four-stroke cycle, energy conversion principles, and engine classifications. Provides the conceptual framework needed for all subsequent teardown and rebuild work.

Lesson 1 • Initial Cleaning and Parts Organization

Introduces degreasing methods and parts-washing equipment to prepare components for inspection. Clean parts reveal defects that contamination would otherwise hide.

Lesson 2 • Engine Removal Techniques and Lifting

Teaches hoist setup, engine mount unbolting, and controlled extraction from the engine bay. Safe lifting prevents injury and protects the engine block from impact damage.

Lesson 3 • Pre-Removal Preparation and Fluid Draining

Covers disconnecting batteries, labeling wiring, and draining all fluids before removal. Proper preparation prevents contamination and component damage during extraction.

Lesson 1 • Crankshaft and Bearing Inspection

Covers measuring main and rod journal diameters, checking for taper and out-of-round, and evaluating bearing wear patterns. Findings guide grinding or replacement decisions.

Lesson 2 • Precision Measurement Instruments in Depth

Covers micrometer, bore gauge, dial indicator, and feeler gauge use with calibration procedures. Accurate measurement is the foundation of every rebuild decision.

Lesson 3 • Cylinder Head Inspection

Addresses head surface flatness, valve seat condition, guide wear, and crack detection methods. Head condition directly affects compression and combustion efficiency.

Lesson 4 • Cylinder Block Inspection

Teaches measurement of bore diameter, taper, out-of-round, and deck flatness on the engine block. Results determine whether boring, honing, or replacement is required.

Lesson 1 • Cylinder Boring and Honing

Explains boring to oversize, honing for surface finish, and crosshatch angle requirements for ring seating. Correct bore finish is critical for oil control and ring break-in.

Lesson 2 • Line Boring and Align Honing

Explains main bearing bore alignment, line boring procedure, and align honing to restore concentricity. Misaligned bores cause rapid bearing and crankshaft wear.

Lesson 3 • Cylinder Head Resurfacing and Valve Work

Addresses surface grinding for flatness, valve seat cutting, and valve face grinding angles. Proper angles and surface finish ensure sealing and heat transfer.

Lesson 4 • Specifying and Verifying Machine Work

Teaches students to write machine shop work orders, specify tolerances, and verify finished parts with precision instruments. Verification prevents assembly of out-of-spec components.

Lesson 1 • Main Bearing and Crankshaft Installation

Guides bearing shell selection, plastigage measurement of oil clearance, and crankshaft torque sequence. Correct oil clearance ensures adequate lubrication film at operating speed.

Lesson 2 • Oil Pump and Pan Installation

Covers oil pump priming, pickup tube clearance, gasket selection, and oil pan torque pattern. A properly installed oil system delivers pressure immediately on first startup.

Lesson 3 • Piston Ring Fitting and Installation

Covers ring end-gap filing, ring orientation, and ring compressor use for piston installation. Correct ring gaps control blow-by and oil consumption from the first startup.

Lesson 4 • Connecting Rod and Piston Assembly

Teaches rod bearing clearance verification, rod cap torque sequence, and side clearance measurement. Proper rod installation prevents bearing spin and journal damage.

Lesson 1 • Valve Spring and Retainer Assembly

Teaches spring compressor use, keeper installation, and spring pressure verification. Proper spring tension ensures complete valve closure at all engine speeds.

Lesson 2 • Valve and Seal Installation

Covers valve stem seal selection, seal installation tools, valve insertion, and spring seat placement. Correct seals prevent oil consumption and maintain combustion integrity.

Lesson 3 • Head Gasket Selection and Installation

Addresses gasket material selection, surface preparation, and head bolt torque-to-yield procedures. The head gasket seals combustion pressure, coolant, and oil passages simultaneously.

Lesson 4 • Camshaft and Timing Component Installation

Covers camshaft bearing installation, cam timing marks, timing chain or belt tensioner setup. Correct cam timing determines valve events and engine performance.

Lesson 1 • Lubrication System Final Assembly

Addresses oil filter adapter, external oil lines, and pre-lubrication before first startup. Pre-lubrication prevents dry-start bearing damage during initial cranking.

Lesson 2 • Ignition and Fuel System Reinstallation

Guides distributor or coil-on-plug installation, injector seating, and fuel rail torque. Correct ignition timing and fuel delivery are essential for a successful first start.

Lesson 3 • Engine Installation and Pre-Start Checks

Covers engine reinstallation into the vehicle, reconnecting all systems, and a pre-start inspection checklist. Systematic checks prevent costly damage during the first startup.

Lesson 4 • Intake and Exhaust Manifold Installation

Covers gasket selection, manifold alignment, and torque sequences for intake and exhaust manifolds. Proper sealing prevents vacuum leaks and exhaust leaks that affect performance.

Lesson 1 • Compression and Leak-Down Testing

Teaches compression test procedure, leak-down test setup, and interpreting results by cylinder. Results confirm ring seal, valve seal, and head gasket integrity after break-in.

Lesson 2 • Initial Startup and Break-In Procedure

Covers first-start monitoring, camshaft break-in RPM protocol, and oil pressure confirmation. Proper break-in seats rings and cam lobes, establishing long-term engine durability.

Lesson 3 • Post-Break-In Inspection and Adjustments

Addresses re-torquing head bolts where applicable, re-checking valve lash, and inspecting for leaks after heat cycling. These adjustments lock in final sealing and valvetrain settings.

Lesson 4 • Diagnosing Common Post-Rebuild Issues

Identifies causes of low compression, excessive oil consumption, overheating, and abnormal noise after rebuild. Systematic diagnosis prevents repeat failures and guides targeted repairs.
