I made a new limiter the same as you did but still had problems with it slipping into the grease cup. I found that a Dash #021 Buna 70 X-Ring fits the bottom of the grease cup perfectly so I used o-ring glue to attach the x ring to the top of the 1/32" thick buna 40 disk that i made. This has fixed the problem for me.It's not designed to take grease continually. It will of course if the gasket is removed and then that excess grease needs to be removed if it happens. My compressors gasket decided to slip into the cup and allow all the grease to be sucked down onto the crank. I contacted their customer service and was told to remove that excess grease out of there and make sure not to allow it to happen again or it can cause problems.
I had some thin rubber so I used the grease cup as a template and made my own with a tiny hole in it just like the factory one (too bad these aren't available)
The problem is the gasket was so ripped that it wouldn't stop the grease from entering when the pump is running.
How it's supposed to work is there is always some suction happening as the machine runs but the grease is supposed to be limited by that faulty gasket. After every 4 hour cycle, you are supposed to turn the screw one revolution to put some pressure onto the gasket and that tiny hole allowing a small amount of that grease to have enough pressure to make it through the tiny hole.
