Where are the timing marks on a 1989 Toyota Tercel so that the ignition timing can be adjusted at the distributor?

Answer 1

There typically isn't any timing marks at the distributor. It is possible to slightly advance or retard the ignition (spark) timing by rotating the distrubitor but as far as timing marks go, the only that you will find will be right above the camshaft sprocket and the harmonic balancer (crankshaft pully). possible one more for the oil pump or countershaft.
