This might sound really stupid but how do you check the oil in the Vortech V3 head unit? Their are two brass fittings, the top is supposed to be the vent and the second half way down the blower is supposed to be the dipstick I believe. I removed both and their is no dipstick attached to either. I also removed the lowest plug on the side of the head unit that is silver with the magnet just to be sure. The fluid I drained out didn't even fill one of the small oil containers Vortech gives you the new supercharger oil. None of the manuals either online or the actual manual tells you anything.
