how do i know if this is the problem?
not really a "problem" per say, its just an explanation on the source of what i would call the sound of tapping a quarter on a wood table. different oil filters can help somewhat, but ime never completely cure it.
is there a way to know if this is my issue?
a cracked manifold would most likely do it constantly and get louder as the engine rpms go higher.
