First is limited movement, which affects motion accuracy. It affects the sealing performance. Second is the minor assembly error, which has no impact. Third, increasing the additional stress accelerates wear. Fourth, it leads to poor lubrication.

Agree with the opinion above; additionally, the bushing of the lower valve rocker arm tends to break, resulting in the lower valve not closing properly or getting stuck

It may cause the lower valve cylinder to break
