I try to keep everything clean as possible.... Makes working on it alot easier and cleaner...

That's near where I put mine. There was a small factory hole that I mounted the bracket to, and a larger hole just in front of it I could stick my hand in and reach the back of the bolt to hold a nut on.
The battery shelf comes in handy when draining. Mine has a small ball valve at the bottom and I just place a small butter tub underneath and let it drain while I'm changing the engine oil.

Have a drain valve in the bottom of it? If you haven't already, I recommend cramming a stainless Scotch-Brite scrubber in there. It'll increase the can's effectiveness. Of course, with the scrubber in there, you don't want to have to unscrew the reservoir to drain it, so a 1/4-turn ball valve in the bottom like what @gooffeyguy has would be really convenient.

It has the provision for adding the fittings for a valve.. I plan on doing it soon, Figured I would get it in, then add the valve and scrubber on next oil change... Plus it gives me a good benchmark for how effective it will be with scrubber and without...

No testing necessary- the more coalescing media it has, the more oil it'll catch. It's not like an air filter into the engine where you have to maintain at least a minimum amount of flow. You wanna filter as much as possible, even if it presents a decrease in air flow volume. You can't filter it too much and a loss in flow won't affect anything.
Mine consistently caught 2 ounces every 5,000 miles. After the scrubber, 3 ounces consistently.

I’ve had mine in for 1500 miles or so and it’s bone dry...

I put one in on the vette on my avatar.
Was just an empty can, but cheap and fits a morso clamp.
Built my own baffles and put one of those scrubbers at the bottom.
Used a tube from the valve cover side to ensure the oil gets to the bottom of the baffles and would need to make its way up.
In the vette, #2 cylinder likes to get all gunked up with carbon, and a nice oily streak down the intake runner to that cylinder...
Fixed the issue with the catch can...
I'm sold on the idea afterwards.
It always catches nice dirty oil and water.
Not wanting to re-research the thing i bought the same thing for the hoe.
I'm not quite there yet but it did wonders for the vette, and since i have the engine totally clean i figure i might as well keep it that way.
On the vette i just remove the canister from the clamp and drain, but i'm looking at some method to easily drain it since that's a pita.
I thought it was 1/4in npt, but it's apparently something else...
glad i own a drill and a tap set.

my hoe was amazingly clean when i took it apart.
Worst looking part so far was in the intake side of the heads.
Cylinders/Pistons were amazingly clean, valves had crud but not too bad for the mileage.
I don't expect to catch much with mine, but should it pass any extra oil i'll know.
+ a good way to keep track of blow by and engine changes...
For the vette, i bounce that thing off of the rev limiter often (currently set @ 6k RPM)...
Of course, should i one day blow the engine in that thing, it's 383 stroker or LS swap time.

I also have this addiction to air tools...
A few years ago i bought one of these "used" off of ebay for about $50 iirc.
https://www.amazon.com/dp/B01CYD2NS2 (Astro Pneumatic Tool PRN516 ONYX Pneumatic Rivet Nut Setting Gun W/Quick-Change 1/4" & 5/16" Mandrels)
The prior owner was kind enough to have the 1/4in adapter already converted to use standard hex bolts.
Making changing the mandrel cheap and easy.
Takes a bit of a learning curve since you can snap/strip the 1/4in mandrel very easy if the pressure is too high... lol
I have gone out of my way to find uses for the tool ever since.
Including rivnutting the back of my riding mower for a receiver hitch adapter.
Once complete, i accepted that i probably would have been better off with a through bolt and a nut on the back side, but it's so slick for something that I'll never remove.
Even riv nutted an oil pressure gauge mount...
why? because i can...
Expect some nice riv nuts for my catch can install.

Just thought this was odd as it’s going on 218,000 miles.

Depending on the design of the catch can, that might be a reason why your not seeing anything.
want to make sure that any oil vapor has to work it's way into the intake, and keep in mind that it want's to stick to things like baffles and mesh.
My setup works very well in the vette.
Mesh at the bottom, valve cover side has a little tube that goes nearly to the bottom of the can and mesh.
The intake side is at the top.
baffles to mix up the air, alternating side to side as it rises.
And a screen at the top to hopefully catch anything else that makes it that far...
Not all catch can designs are equal, part of why i prefer an empty can that can be opened.
Allows me to play with it.

Man no amount of money will ever get me to do any work on a c4 corvette ever again. I redid the entire brake system on a 93 and a hard top since the vert top was shot. That lt1/4 is *****. The l89 was a better design. Got it running and sold it. Had a ZF too.
