SuperCharger Knocking...

I thought I have been experiencing engine knock but it turns out its the super charger knocking, somewhere inside the casing. Is this normal or somewhat common? Ive only had the car maybe 5 weeks. It is low on oil but not empty. Thanks!
 
Mine is running quieter after I replaced the snout seal and filled it with Royal Purple 5w20. The synthetic oil is just temporary until I can make it over to the aviation store to get a qt of BP turbine oil, but anything is better than running it dry :eek:
 
I bet you've got the solid plastic coupler instead of the spring type inside. The coupler connects the snout shaft to the back half of the sc. Once the coupler loosens up from wear it rattles like a diesel engine. It's annoying but not a serious problem. The spring type coupler tends to fit tighter.
