Basically, You cannot set timing is correct... But, turning the distributor serves only to adjust what GM calls the cam retard offset. Actual ignition timing is controlled by the PCM, based on the information it receives from various input sensors. To adjust the cam retard offset, connect a scan tool to the DLC. Bring the engine to operating temperature, then hold it steady at 1000 rpm. Monitor cam retard offset on the scan tool. It should be 0 2. To compensate for a negative reading, rotate the distributor in a counterclockwise direction, To compensate for a positive reading, rotate the distributor in a clockwise direction. Recheck the reading after tightening the hold-down bolt. It may change. Also note that attempting to retard the cam retard offset reading outside the recommended range will not cure spark knock, and may cause the PCM to store a diagnostic trouble code.
That requires an obdII engine scanner.
It requires an engine scanner to set the timing on that year engine.
how do you adjust the timing on a 1977 350 Chevy engine k-10
It has timing chain and gears. NO belt.
There should be a sticker on the fan shroud telling you which wire to disconnect. On the older tbi motors it was tan with a black stripe i believe. Disconnect this wire, the loosen the dist. bolt and check the timing with a timing gun. Rotate the dist. until you get the desired timing then tighten the dist. bolt and connect the tan wire. On a vortec engine you have to have a engine scanner to adjust the timing. But if there is no check engine light on then the timing is correct all ready. It is controled by the computor, There is no ajustment needed.
The timing on y our 1987 Chevy Celebrity is controlled by the engine computer, there is no way provided to adjust it.
That requires an OBD2 engine scanner to set the timing.
THE TIMING IS COMPUTER CONTROLLED. It requires an engine scanner to set the timing on that engine.
On the Vortec the computer does it all.
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
It does not have one. The timing is controlled by the computer. You must have a OBDII engine scanner to adjust the timing. If you did not have the distributor out are move it then there is no reason to adjust the timing. It is done automatically by the computer.
That requires an OBDII engine scanner to do that.
That requires a OBDII engine scanner. You can not use a timing light. The timing is computer controlled.
