The fuel injectors can fail and cause drivability problems. Often there is no Check Engine light and the failures can be caused by corrosion of the connector, clogging beyond the point of cleaning, and/or internal failures.

The coolant outlet on the front of the lower intake manifold may develop a coolant leak.

Valve clearances for this engine are shim adjusted and should be checked periodically to help maximize engine life. Another good time to check the valve clearances is when the valve cover gasket is being replaced.

The distributor shaft bearing can become rusty, and seize causing the engine to stall or not start. The failed distributor will commonly require replacement.
