GM LT1/LT4 5.7 liter engine (1992-1996) Optical Spark Distributor system (tune-up) Pt 1/2
The video we expose the internal of the Chevrolet LT1 front engine mount electronic distributor (hi-voltage).Part of a Complete Tune-up processor. HERE we explain the inner workings of Hi-Voltage Distribution Part. This component can be found on the corvette,caprice,GMC trucks,Roadmaster,Cadillac. Subject: theory and testing of Opti-spark(optical) systems Contributing Source: General Motor service manuals and training materials The General Motor Opti-spark ignition system is used on 1994-96 4.3-liter L99 (VIN W) V-8 engine and on 1992-97 5.7-liter LT1 (VIN P) V-8 engines. The Opti-spark distributor is mounted on the front of the engine block, above the crankshaft. The distributor is driven by the camshaft. Opti-spark system rely on two optical cam position (CMP) sensors mounted inside the distributor. Beginning in 1996, Opti-spark equipped vehicles also included a crankshaft position (CKP) sensor mounted at the bottom of the timing cover, The PCM uses this CKP sensor only for misfire diagnosis, not ignition timing. This sensor is not part of the Opti-spark system. The Opti-spark CMP sensor provide signal to the PCM (Powertrain Control Module) for ignition timing control. These sensors detect slots in the crank-driven signal disk. One CMP sensor detects 360 equally spaced slots per camshaft revolution, for high-resolution timing control. The other CMP sensor detect eight signal disc slots, the CMP reference signal toggle between 0.0 and 5.0 volts. The PCM compares the two CMP signal to determine if one of the inputs is not being received.

(COMPLETE) ENGINE TIMING BELT SERVICE with TUNING - NISSAN VG33E SOHC V6 VALVE TIMING
A full length video of replacing the engine timing belt on a single over-head camshaft V6 engine. The method and technique in this video can be consider has a General Application for servicing Automotive "V" Series Engine timing belt. This Technical Troubleshooting is the full-edition of a three part series with a BONUS Tuning inspecton to complete all engine timing belt training and service procedure. This is a expert level of trained mechance's. Timin belt alignment is essential to achieve uptium engine performance. Any mis-alignment with in the timing belt sprocket can be detrimental to engine. Follow this video instructions for most of your engine belt timing. The engine timing belt keep the intake and exhust valve in syconicty with its piston and in relation to maintain cylinder pressure for combustion and the flow of air charge mixture to follow the exhust gas evacuation fron the ignite pressure charge mixture. All air charge mixture is consist of a 14.7:1 ratio. 14-15% of the fresh air charge mixture is consist of gasoline in its vapor state.
