so i just installed a kenne bell supercharger on my 2000 mustang not too long ago. the other night i snapped the throttle quick and the heater hose blew. i only like 5mins from there so i milked it home, or so i thought. the next day i put a new heater hose on filled the system back up and found out i was a quart low on oil. i put it up on a jack and there was oil on the bottom of the car, drippin down from above the starter. it looks like it was comin from where the head meets the block. (headgaskets?) now it is not leaking and oil but there is a hesitation in the low rpm's. it kinda sputters and then goes. kinda seems like a vacuum line leak but i have a feelin thats not it. like to hear from anyone who might know what causes this. thanks
