Engine Mechanical problem
1992 Toyota Corolla 4 cyl Front Wheel Drive Manual 181000 miles
Oil is puddling around the exterior of the spark plugs #1 and #4. The spark plug is located within holes in the valve cover. What is causing this? Does it need to be fixed?
The engine began to miss, so I changed the spark plugs, wires, distributor cap and rotor. This corrected the missing. The oil puddling around one spark plug was probably touching the porcelain.
Once in a while one of the spark plug wires pops up about 1/4 inch above the top of the valve cover that it plugs. This doesn't seem to cause the car to miss.
