An easy way to tighten up the PCV 'f-pipe' rubber coupler is to wrap a layer of electrical splicing tape (not regular electrical tape) to the nipples of the pcv valves themselves. As this is a thicker rubber, self sealing type of wrap, it will really grip to the original rubber grommet and won't have that barely fitting loose feel.
