i want to see the diagram wiring from the engine block to the distributor cap please.
I really depends on what distributor you have on the engine. It could be a mechanical advance distributor or a vacuum advance distributor (stock). Google "the Somba" Volkswagen forum and all will be explained.
By rotating the distributor.
The wiring diagram from the distributor cap to the spark plugs for firing order for a 93 Chevy Caprice 5.7 liter engine is found at Wiring4cars. You can search the site by vehicle year, make, and model.
Advance the distributor until the engine pings then back off to the point the engine stops pinging, tighten the distributor. This will require driving a few test runs.
Distributor Advance is the wrong term; the Distributor Advance system implies actually moving the timing components of the distributor to control timing of spark in the engine (A Vacuum Advance, is an example of this). Modern controls use computer spark mapping, through learned routines or factory set timing models to control the spark based on these tables, through the computer. In all essence it is the computer that controls all spark functions.
When messing with the wires of an engine it is important to have a diagram. The diagram can be found a the maintenance, or repair manuals bought at car part stores.
It is the octane number range the distributor automatic spark advance can handle without the engine knocking.
To advance ignition timing, loosen the distributor clamp and in very small increments turn the distributor body in the OPPOSITE direction of the rotor's normal rotation. If you don't know which way the rotor turns, you can find out easily by removing the distributor cap and having a helper turn the engine over with the ignition key switch. To advance the timing turn the distributor counter clockwise.
Rotate engine to TDC Intake Stroke Remove Distributor cap Remove vacuum line to vacuum advance if equipped Remove horsehoe type clamp on side of distributor Lift out distributor
The distributor is off a tooth or two. You can pull the distributor out and turn the rotor a little and put it back in. Then re-time the engine.
Does anyone have a diagram for the Vacuum connections for a 1985 5.7 L Tune Port Injection Corvette engine?
>you don't adjust the vaccuum advance. you adjust the distributor. then when engine is running the vaccuum advance will work automatically to the needs of the engine< As a matter of fact, the Ford vacuum advance is easily adjustable. Put a 1/8" Allen wrench through the open of the vacuum advance canister where the vacuum hose goes. Screw it in to slow the rate of advance and screw it out to speed it up. I think it works on a spring preload system.
Yes it does. Clockwise retards it. Counter clockwise advances it.
where are the coil wires located, and where do they hook up
It won't. That vacuum line tells the distributor When to advance the timing. There isn't enough vacuum loss to stall an engine.
Ist is a simple process. Simply remove the vacuum line to the advance mechanism, then remove the bolt that hold it down to the block. (Just to the left) Then lift the distributor from the engine. (Carefully allow the distributor to rotate a bit as you pull straight out.)
Firing order for you're Rocket engine is 18436572 distributor rotation is counterclockwise. Cylinder one on the distributor cap points to cylinder one.

looking from the top of the motor, the distributor turns clockwise. If you have a vaccum advance mounted, the vaccum line is always pointing opposite the rotation.
The firing order is ( 1 - 5 - 3 - 6 - 2 - 4 ) The distributor rotor turns CLOCKWISE The marked # 1 position on the distributor cap faces AWAY from the engine The engine cylinders are numbered 1 to 6 , from front to rear of engine
