Right basically I rebuilt my supercharger but on fitting and startup it pissed oil everywhere.
Turned out to be a seal I had accidentally nicked when fitting to the scroll.
Anyway swapped the scroll out for one from a known working charger.
When I turned the charger by hand after the new scroll was fitted it turned fine. But on the car it started making an odd clicking/knocking kind of noise.
Took the charger back off and if I quickly rock the pulley back and forth I can hear and feel a knock but I can't pin point where it is coming from.
Any ideas greatly appreciated, really need the car working :(

did the counter balance weight go on without any force?
you sure you got that the right way round (and the one on the countershaft right too)
-
Right cracked the thing open again and found that there is about 1mm of up-down play in the top counter balance.
Is this what I'm hearing? It's all I can find. Everything else is nice and solid.
-
it should be flat side up.
take the circlip off and keyway out. rough up the keyway with side cutters and refit. Should be tighter now.
Is it a jabbasport marked counterbalance weight by anychance?
-
I've changed the keyway and counter weight over from the other charger (this thing is turning into a bit of a frankenstein) and it is a tighter fit.
The counter weight isn't marked with a JS number, but the one on the shaft is.
Refitted the casings together and if I put my fingers through the outlet and stop the counter weight moving I still get a little play.
Should it be completely solid?
-
no - sometimes theres a little play.
one thing to mention is to weigh the counter balance weight on the main shaft that says www.jabbasport.com jabba sometimes used to 'balance' them - which means they often are lighter than stock ones and don't balance! causing a vibration
-
Well put it on the car and it sounds a lot better now, no oil bursting out of it this time either which is good.
All I can hear now is the whine from the toothies, so I hope all is well.

All good then!

Thanks for your help Pete :)
