Yeah I got around to changing it back in late January when we had a nice blast of some decently warm weather. I had also found that my front exhaust manifold had cracked as well. I had a list of things to do and some time to do it. Most of the difficulty was ordering parts from GM as I came across things that needed to be replaced that were unexpected. The aftermarket was out of stock on things like throttle body gaskets, fuel injector seals and so on. GM special ordered the pieces in and I managed to get the whole thing back together over the course of 3 days including replacing the exhaust manifold that I found on a 57,000 km 1995 supercharged Buick Park Avenue that I found at the wrecker for $35.00. Sure a whole lot cheaper than the 265.00 from an online parts store. The whole thing has been together for 3500 trouble free km since and everything seems to have worked out perfectly. I changed the nostril bearings, outer seal, and greased the needle bearings for the rotor at the back of the supercharger with that special high heat grease from intense racing. The supercharger is whisper quiet and cannot be happier with it.
I have mentioned that I have changed the supercharger fluid on the car every 10,000 km since I got it 4 and a half years ago and the supercharger has always been nice and quiet and there was no putrid smell from the fluid when I popped open the casing, infact it was actually very clean internally. The bearings were in good condition but I opted to change them as I had already ordered them and had the thing apart.
Special thanks to Graham who sent me an email asking whether I have rebuilt the supercharger or not. I tried to respond and found out I am too junior a member or such to send a PM back. Thanks to everyone else who helped out with info. The whole project went off without a hitch.
