How to Solve the "Ticking" Sound in Focus Engine?

[McEmmanuel]

Ford Focus engine making a "ticking" sound may be caused by poor oil quality. Additionally, the "ticking" noise is generally from the valve or fuel injector. The causes and solutions for valve-related noises are as follows: 1. Worn or broken valve spring seats may cause noise—replace the valve spring in this case; 2. Excessive or inconsistent valve clearance can lead to noise—adjust the clearance to resolve the issue; 3. Worn or misaligned valve adjustment screws or loose lock nuts may also produce noise—adjust the screw tightness to fix the problem; 4. Too high or too low oil level in the crankcase can cause noise—check the engine oil level; 5. Worn valve guides may also result in noise—inspect or replace the valve guides; 6. Dirty lifters can cause noise—clean the hydraulic lifters; 7. Out-of-round valve seats or valve faces—grind the valve and valve face; 8. Incorrect oil viscosity selection may also cause noise—switch to a higher viscosity grade oil.
