Hello all, Just thought I would share my solution to the dreaded Procharger seal leak issue. I know a lot of people with self contained Prochargers have issues with the seals leaking and it seems the culprit is that the case does not have a way to vent. I know from first hand experience that pressure is indeed building inside the case (I have a P-1x) because after running for a while, I can crack open the dip stick/plug and it hisses and spurts a bit. Try it for yourself and you will see that the heat inside definitely raises the pressure to a positive value in a matter of minutes. After searching for simple solutions, I found that the Vortech/Paxton plug has a vent hole already drilled in it. ( Vortech PN 7P375-058) So why the hell wouldn't the SC Prochargers have the same thing? To me it looks like the thread pitch/ size is the same as the plug/dipstick for the Procharger, but I did not verify this nor was I interested in paying 33 dollars for a plug, plus 10 dollars shipping. Instead I re-created the same thing with the Dipstick, and drilled a .073 hole into the side, and down between the slot in the top. You could go smaller with the hole, but anything bigger wouldn't fit in the slot. Just make sure your hole clears the gasket. Also, you don't to drill the bottom because that is where the dipstick cable is crimped on. So far, I have been running this way for about 100 miles, and it seems to be working. No more pressure release when I open the plug. I think there is just enough space between the threads to leak the pressure past and out the top, and this also seems to keep the oil in, but leave just enough room for the pressure to escape. I hope this helps others here. Certainly better than rebuilding simply due to leaking seals. I will report back when I have logged more miles.
