What does it mean if I put air to the top of the wastegate and I hear it coming out the side port of the wastegate?

Usually means you have a hole in the diaphragm

That is what I was afraid of. How or why does this happen?

I'm not sure exactly why or how it happens, but it does. I have had a FPR where the diaphragm got a small hole in it. And know of several people with the wastegate diaphragm problems. I don't know if it was from debris, heat, age, or what? A lot of times it's from taking it apart and not putting it back together properly, at least in some of the ones I've seen.

i see this all the time on cheap ebay wastegates

i have never seen a tial do this unless it was taken apart and put back together wrong

It happens on Tial gates sometimes. The 4 little set screws will work themselves loose and the top cup assembly 'wobbles' on the valve. The side to side movement is enough to make the diaphragm contact the bottom banjo bolt where it protrudes into the housing. If you trim a bit off the banjo bolt it prevents that possibility.

usually from what ive seen the diaphram will pull its self out of the slit. usually good for a couple tenths when you replace it lol

-pinched diaphragm
-diaphragm is not sitting correct on the bottom half
-someone took it apart and didn't use locktite on the set screws that hold the vlave in place
- you hooked it up to a vacuum source (which is says not to per instructions and i have said numerous times on here) and the vacuum sucked in the diaphragm and slit it
- the washers were not installed correctly (or at all) and the air fitting was screwed in too far hitting/damaging the diaphragm

if it's an older wastegate the diaphragm might have broken free of the spring cup
