In some engines, clicking and ticking noises may occur when something as simple as low oil level is present, but may also indicate a valve sticking, loose cam chain or other valve train problems.

grinding, as there is nothing available to quantify the finished cam to. This is a real problem for the grinder when checking the Jerk or 3rd derivative of the production cam, as Jerk can get very large in all the wrong places during grinding without the original data to compare.
