Question about 1985 Toyota Corolla 2 Door
Actual timing would depend on what engine is installed in the 1985 Corolla. There are some versions that uses the 4A-GE, 4A-GEC, 4A-C engines. There are even some Asian versions that used the 4K/B engines.
The correct method would be to use timing light, engine analyzer and some other test equipment, However, below is a quick and dirty procedure. Basically, to adjust the distributor timing, you need to:
1. make sure cylinder 1's piston is at firing position/TDC (top dead center);
2. crankshaft pulley's timing mark is between the markings on the engine with numbers on them;
3. unplug the rubber boot of the high tension wire for #1 cylinder;
4. connect to it a spare known good spark plug and allow to touch any metal surface of the engine;
5. slightly loosen the single locking bolt of the distributor stem;
6. turn ignition key to ON but not start;
7. carefully swing the distributor assembly till there is spark in the exposed spark plug;
8. tighten locking bolt.
You may need to readjust the distributor for highest idling RPM with the engine running by simply turning the entire distributor assy.
The timing mark must coincide with the specified advance for whatever engine is used by the Corolla. 8 degrees would be a fair start.
Extreme care when working with engine running; extremely high voltage at the high tension wires, distributor and ignition coil and the fan/belt has been known to catch loose clothing.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
