Didn't see that anyone else has done this, so I thought I'd share a really simple / perhaps dumb idea.

I've always known that these self-contained Procharger units build up some pressure within the case as the supercharger heats up. After changing fluid, I always loosen the dipstick screw once it reaches operating temperature to relieve that pressure, because I suspect it's one of the causes of leaking seals. A little bit of fluid always spurts out when I do.

So, I thought instead of worrying about it, why not just vent the case?

1) What the dipstick looks like (gauged the threads to be 5/16"-18tpi):



2) I found an old brake bleeder screw I had laying around:



3) Used a tap and die set to cut the necessary 5/16"-18tpi threads (Note: this is on a D1sc -- not sure if other head units use a different dipstick thread):



4) Pop a hose on the bleeder screw, and you've got yourself a vent:


5) Installed. (Forgive the dirt -- my BOV is near the ground kicks dirt up everywhere):


Put on a small filter I had laying around:


At any rate, this should help prevent any leaks in the future (though I've had no trouble thus far).

Figure I might be able to use that hose to refill the system as well... or it might sputter and make a mess. Haven't tried that yet.

I don't have one of those, but agree it is probably a good idea to vent the pressure. Good innovation!
