1995 Toyota Corolla shreding timing belts

Visually check belt alignment, that is, belt should be straight as you look down at it.

Look for any contamination (oil, coolant) on timing belt.

Look at lower cog on crankshaft for wobble or worn slot where it slides into woodruff key. If woodruff key slot on cog is worn, cog will slide back and forth causing wear.

Check notches on camshaft pulley for missing notches or sharp edges. There is a small thin steel guide that fits on outside of lower cog, make sure it is installed properly. If installed backwards it will cut into belt.

Check above and let me know what you find.

Is this 1.6 or 1.8 engine?
