Default small screw to plug CAC

Last night I screwed in a small metal screw to plug the cac hole I previously drilled to relieve the hesitation issues I was having.
The only concern I have is, over time, could the tip of the screw corrode and then cause the corroded piece of metal to fall of and end up in the engine when air is sucked in from the cac? I would think perhaps the perpetual stream of oil will keep things lubricated so corrosion wouldn't be an issue. Any thoughts?

Why did you decide to plug it? Drilled mine about a year ago and haven’t had any ill effects. No more hesitation either and no puddling of oil from it.

Install a catch-can/separator in the PCV line to get the oil out, if oil discharge is an issue or concern. Either way I'd leave the screw out.

I don't think the hole in your CAC is your issue unless you drilled a big hole. I would remove it and clean it out thoroughly though if you haven't.

No the cac isnt the issue. Issue was the spark plugs. Now that i see it isnt thw cac i want to plug it up. Dont like dripping oil here and there on my or someone elses driveway. I took the screw out again though, but now the hole is a little bigger than i would like...

Don't use a screw. Use a small blob of rtv sealant. Let truck sit overnight to cure. It's under pressure anyway.

Leave it open. You could develop condensation or oil buildup over time.

I'd leave it out, I get some on the lowest valance but after the initial drain I haven't seen a drip on ground since and its been probably a year.

Is high temp rtv strong enough to hold the pressure? Also, will it cure correctly considering there is oil on the inside of the cac?

I think I may go that route, however now the hole is not 1/16, it's more like 3/32 after inserting a srcrew then removing it. isn't that going to be too big considering the pressure could seep out of a hole that large?
