whistling occurs as air passes through a small hole. my guesstimate would be that the smaller holes you had previously didn't whistle because it was higher pitched and wasn't audibly detectable by you. now that the hole is 1/8", the note became much lower and audible. you can try drawing slower? or try ignoring it. the harder you draw the more it'll whistle.

You could, but top caps can get pretty hot and I know I don't want to be vaping any gasses that the JB weld may release when heated. Buying a new top cap would be the best approach, imo.

i second that. i wouldn't risk anything with air contact getting contaminated before my lungs.

I just drilled mine out to 1/8 as well. its silent when i draw on it very light but when i hit it normally i swear my whole house can hear this thing (all the neighbors too i would imagine lol) when i suck on it really hard (hehe) the whistling does stop but when i stop my hit, it whistles for a split second.

i will be trying to sand off those burrs and see if anything helps. oh and also ive noticed that only 1 side of my cap whistles. when i put my finger over the hole maybe 1/4 of the way,on the one side, it stops whistling

Take a large bit (I used 1/2") and very slowly drill out a small amount around the hole. No more whistle.
