I've been trying to find a cheap BCA for my " '95 SSEi" sueprcharger. The dealer wants $300+ for that dumb little canister, and GMpartsdirect wants half that. Still too much, to me.
I gave Magnuson a call and asked if I could purchase a BCA by itself. They said yes, for $40
. That'* reasonable. I recieved it from them yesterday and installed it. It looks very similar to my stock one, though made out of plastic instead of metal.
However, whenever the engine is running, the shaft is retracted, giving full boost at idle. Off of the */c, it feels like the rod moves fine, but is not as resistive to movement as my stock one, which I think is the problem. When I disconnect the top vacuum line, the rod extends, and gives no boost at idle (like it should) but retracts all the way again when plugged back in.
I gave a call back to Magnuson, and they said it must be defective, and are shipping me out another one (they're new, btw). Their service is excellent. But, am I missing something to this? I studied what I did, and there'* not much to it. I loosened the two 10 mm bolts that hold it to the */c and tried different angles (from what I've read, have an effect on how responsive the BCA is) but nothing seemed to help. It'* not like it'* binding; with the engine off, I can move the rod and the little arm like I could with the old one.
Thanks guys. Has this ever happened before?
