Problems:
Head gasket failure
The 4A-C engine in the 1986 Toyota Corolla is known to suffer from head gasket issues, which can lead to coolant leaks and overheating.
Carburetor problems
This engine uses a carburetor for fuel delivery, which can become clogged or malfunction, leading to poor fuel economy and performance issues.
Oil leaks
Older engines like the 4A-C are prone to oil leaks, often from the valve cover gasket, oil pan gasket, or front and rear main seals.
Timing belt wear
The 4A-C engine uses a timing belt, which needs regular replacement every 60,000 to 90,000 miles to prevent engine damage.
Valve train noise
Over time, the valvetrain components such as lifters and camshaft can wear out, leading to increased engine noise and potential performance problems.
Cooling system issues
Radiators, water pumps, and hoses can degrade over time, leading to cooling system failures and engine overheating.
Piston ring wear
High mileage engines can suffer from piston ring wear, leading to excessive oil consumption and reduced engine compression.
