Can a supercharger getting hooked up on a stock supercharged Riviera be bad?

What is your question?

I am looking at trying to replace the oil pan and transmission pan on my Buick Riviera it is the supercharged engine of course but it is the M60 instead of the M90 not only have about the modular pulley for the supercharger I have also replaced quite a few of the other police including idler pulleys. I would like to know if the vehicle is leaking from what seems to be the valve cover if there could be more of an issue there than meets the eye because when I bought the vehicle the supercharger was not hooked up, it is still not hooked up because I am afraid that the extra pressure is going to blow and or damage internal parts. Please get back to me as soon as possible thank you for your time and have a great day

What makes this problem better or worse?

The problem is not knowing how bad the pressure is on the engine when connecting the supercharger and it pulley sets

How long has your 1998 Buick Riviera had this problem?

About 12 days but I had the car for about 4 months
