I don't recycle the oil back in yet, because I don't like my homemade catch
can and I want to redo it. I also don't like the location, which as I
mentioned before, dumps oil in front of my tire if it leaks.

Correct. The crankcase opening is pretty huge, so we made a fitting out of a
pipe end cap and then we tapped and fitted a male end. I can snap a photo
if you want an idea.

Yes. You will also need to plug the hole in your intake boot, where the
crankcase is vented to in the first place.

Not oil cap, but to a tapped fitting in the oil pan (or similar).

I have seen grassroots race cars that use plastic soda bottles or oil
bottles or you can buy up to a blingy Greddy. All is available in between.
I made one out of a paint can and fittings from Home Depot:

(that doesn't go anywhere). The downside is that it's a hassle to empty and
for the price of some catch cans (cheap), I would prefer the convenience of
a sight window and especially one that has a drain valve (if I don't want to
do the oil return). Basically, any raceshop will have them. Try Summitt,
Pegasus and the like.
