1998 Toyota Corolla Problems
RepairPal has identified the most common problems with the 1998 Toyota Corolla based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Drivers of the Toyota Corolla may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.
This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings.
The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced.
To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used.
There are occasional reports of daytime running light problems.
The Toyota Corolla 1.8L produced between 1998 and 1999 has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues.
The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).
Symptoms related to this issue:
- Rough idle
- Backfiring through exhaust or intake
- Illumination of the check engine light
- OBD Trouble Codes P0300, P0301, P0302, P0303, P0304
- Loss of power
- Engine Stalling
To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.
At 125,000-150,000 miles, the Brake Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes can drag and over heat.
The Evaporative system may have problems with the vapor canister releasing charcoal pellets that plug the vent valve. Typically a Code P0441, P0442 and P0446 will be set. The key code is the P0446 which is a vent valve electrical failure. The proper repair is to replace the entire canister with all the valves as a unit. This is located on top of the fuel tank and is expensive. Our Technicians tell us that for awhile Toyota was covering these problems, but this may have changed. It would not hurt to call the dealer if this problem occurs to see if Toyota is still helping with these repairs.
