The timing for this engine is electronically controlled and not adjustable
The timing on that year engine is computer controlled. It requires an engine scanner to set the timing. YOU CAN NOT USE A TIMING LIGHT.
8 degrees before top dead center.
Bring it to a shop and have them adjust the timing with a timing gun I believe its 6*
That requires an engine scanner.
there was no 350 in the camaros in 83 just 305 and v6
about 16 degrees btdc
cam timing will not change ignition timing i would try 8 or 10 degees advance at idle with the vacuum advance disconnected.
it is a knock sensor that is used to adjust the ignition timing.
The timing is set and adjusted by the Engine Control Module according to driving situations.
try adjusting the ignition timing(or getting a mechanic to do it)
I believe 88 and earlier 305's have a nylon coated cam gear that is supposed to make them run quieter but are prone to failure, however chain and crank gear are all steel.
rev the engine to about 2500 rpm's and turn the distributor until you find that sweet spot.
You may have compression on any cylinder where the valves happen to be closed, but you will not have compression on all cylinders. 1991 Sable does not have a 305 engine.
Timing chain jumped? distributor cap is cracked or igniition wire are mix up
looking down from (ONTOP) of the engine they are behind the water pump
what are the timing marks on a chev 305 motor for the year 1995.
they are behind the water pump looking strait down from the top of the engine
Since this category is 305-350, I'll have to assume that YOUR engine is one of the two mentioned. The 1990 Chev 305 and 350 did not use a timing belt. They used a timing chain, and unless something really odd happened, you should never need to replace the timing chain until you rebuild the engine.
You could put a vacuum gage on the engine and time it for peak vacuum. A timing light is still better.
If you will look stright down behind the water pump, you will see the timing tab.
