Passenger side Hood Latch

It should not have failed out of the blue for one valve cover service.




Take note of the hood stop post that adjusts the hood height for leveling and adjust it down for temporary test.
When closing the hood give an extra effort on the failing side (passenger) and see if it changes.
My drivers latch is stubborn but it may be a different scenario.
Cheers
