I’ve never messed with them in an air compressor setup, but I have this article saved. Don’t know if it’ll help or not.

Sorry but I r compressor illiterate.
Yeah that’s pretty much what I built it from .
no experience here, but sounds like you need a check valve or check valve is malfunctioning.
It’s coming from these locations .
Maybe the rings are bad?
I'm not an expert by any means, although I have worked on those units from time to time when they were being used for AC. My question is:
Why the heck do you have anything hooked to those ports?
Remember what these compressors were designed for. Having a "breather" hooked to the oil fill plug would have let the freon out pretty quick.
Take those two units out, and plug the holes.
Note how that article checked the oil level in the unit. Make sure that the oil level is right before you do anything.
The sight glass is not a bad idea, if its sealed and can handle the pressure.
Some folks hook a line with a manual ball valve from one of those ports to an oil separator on the output line. That lets you return the oil that bypasses the rings to the sump.
But, don't open the valve when things are pressurized.
Hope that helps.

It does . It’s more or less what I’ve been thinking also to just Plug them and call it good . First I put the sight glass in it has a vent hole at the top also that’s when this problem began . I just figured the pistons must be creating back pressure that’s when I decided to put the vent in above oil level . I think that’s what I’m gonna end up doing just plugging both holes until I can find a sight glass that will work or find a cap for this one .
I'm sure that there is a small amount of blowby, but what can it hurt? If the crankcase gets pressurized, its just going to leak past the rings in the other direction on the suction stroke.
No idea what kind of pressure could develop even with worn rings. While you are plugging, why not hook a 0-100 psi gauge to one hole and see what you see.
That will give you an idea of how much pressure a sight glass would have to stand.
I do like the idea of a sight glass, since any oil that goes out the pressure side will not return, unlike an AC system. But, some glasses are designed to handle high pressure, such as the old refrigeration sight glasses used to check freon levels, and others are not. Such as the sight glass on a hydraulic storage tank.
If you do hook up a gauge, be sure to post what you find back here in case some others are looking to add a sight glass.

I might just do that I have one laying around I think .
Just plugged the ports and put a gauge in ,it builds up about 45 psi in the case . Gonna try and find a better sight glass too. But plugging the holes worked to stop the leaks lol.
