I have a vortech s-trim, i think it's a v-1 centrifugal supercharger. I have a carb enclosure that the blower is hooked up to. I had to open the enclosure to adjust the carb. The carb enclosure and carb were clean and bone dry (no oil residue). However, I was running the car without the blower discharge duct attached to the carb enclosure (so i could tune the carb). all of a sudden, the blower discharge tube started spewing oil all over the place. I have had the blower for a long time, and haven't noticed blue smoke in exhaust eithern (and as mentioned the carb enclosure was clean (no residue). What are the odds that the blower seal let go right and there, not even spinning the blower fast? OR im wondering (and i know nothing about blower internals) : when the oil comes into the charger via a pressure port, then it passes through bearings and ultimately drips down somewhere into the return line which is not pressurized. SInce the blower was NOT hooked up to the engine (NO backpressure) i was wondering if the oil was escaping through the discharge tube as no pressure was holding it back or making it drip down into the drain line... Does that make any sense or do i need a rebuild? It just seemed odd to all of a sudden leak while i was tuning the car at idle. (or did the seal go bad since it wasn't hooked up to an engine?) thanks for any insight.
