I am working on my stepbrother'* 95 ssei. It is bone stock with 125k miles. Dont know if the supercharger oil has been replaced by the previous owner but he just bought the car from the original owner last summer with 120k miles. It'* been well maintained and all of those miles are pretty much highway.

The supercharger is making a lot of noise at idle now. Not sure what I should do. I'm pretty mechanical but I dont have much experience with these. Somebody mentioned the bearing needs to be replaced. Any good ways to diagnose what is bad? Could he have killed the blower by driving it for a while like this? If it DOES need a new blower, could it have hurt the engine?

Thanks
Henry

Well...sounds like a coupler..NOT the bearings...Coupler is fairly easy to replace...AND then there is the CHOICE of replacing what you can WHILE you are looking at it..ie...bearings, seals, gaskets, etc etc...Coupler by itself...$30-$60 something like that...

And NO..as far as I know...there shouldn't be any internal engine damage...I believe car should even still RUN after */C coupler is blown...at least limping it back to the garage....GOOD LUCK...AND WELCOME TO DA CLUB.......

Thanks for the quick reply. i knew i found the right forum. If the coupler is the common gremlin on these superchargers, Where can I get the entire kit you mentioned?

See the following link:

You have an M62 supercharger. The complete nosecone is available from Magnusson or the dealer for around $400. Or you can rebuild yours like Will did.

I just did this myself about 2 weeks ago on my '95. It was easier than you think. I got the coupler from ZZ Performance for the listed price.I have never dug that deep into an engine before and it only took me less than 8 hours, and I did other gaskets and cleaning while I was in there.

Also, another way to test your coupler is to pull the belt off of the SC and see if you can feel any play between the nose drive and the gears. If there is it will be obvious.
