Sounds Like Rocks Tumbling

So this morning on my way to work i noticed a strange sound coming from under my hood. Being paranoid about my car all the time, I quickly pulled over, popped the hood and pinpointed what seems to sound like rocks tumbling around in my S/C case. I did some research and it seems that my S/C Coupler may be bad/going out.

This being a daily driver, Im wondering how bad this issue is. If its caused/causes any damage to the motor. And If I could possible make it back home without my motor imploding. Ive seen what happens when a washer is dropped down an intake and it wasnt pretty.

Its a 2004 GTP with 105k on the motor.

Thanks...
 


It's not gonna hurt the motor, it's just annoying. You can changed the coupler fairly easy, but do yourself this one favor. The GenV bolts are tight, they're that crappy torque style head, and they have thread locker on top of that. You're likely going to destroy the bolts, so get you a nice set of socket head bolts to put back in when you replace it. You can unbolt the snout assembly, and then slide the rotors out, and separate them over an oil pan so you don't get any oil on the motor. Then reseal the snout to the rotors with anaerobic sealer, torque the bolts down, and give the sealer 12 hours to cure.
 
I second Reptiles suggestion. I swapped mine out and most guys end up fighting them out.

although I'd do it over the motor, rinse after with half a can of brake clean and call it a day. :D
 
Thanks, ive found a coupler on ebay for 24 bucks and imma pick it up this weekend. Ive also found a video to reference on how to do it. You guys are the best BTW, I debated at stopping off at my local tune shop to get an opinion but i just drove to work instead.
 


I agree doing it like that. I replaced my coupler not long ago and that link made it real easy to understand how to do it. Plus didnt have to pay for a whole new gasket for the S/C and it really wasnt that much harder.
 


pulling the snout is much easier than pulling the whole blower off.. just siphon as much oil out as u can with a spray bottle nozzle.
 
The blower weighs 36lbs, plus as I said, the bolts are loctited in, it's going to be easier to take them off if it's bolted to the engine. I'm just saying, I've done them, and if you can take the bolts out, and slide the snout/rotor assembly out of the case, that's one less thing to worry about.

Wrestling with the thing on the floor or a workbench when you're trying to break bolts loose isn't fun at all. Especially with those crappy, easy to strip out star heads.
 
don't forget to wear latex gloves when you do this, as the old oil does stink.

i also second leaving the blower on, just unbolt the alternator slide it back to the fire wall, and start pulling bolts, after the bolts are out put shop rags along the lim and down by the water pump, and that should catch anything that drips out, be sure to suck out as much as old oil as you can first. brake cleaner will take care of the rest of the clean up.
 


I did mine when I first got my car, took about half an hour or so, but I agree that supercharger oil is the worst smelling automotive fluid I have ever smelled in my life, I would rather bathe in burnt differential fluid than to get even a drop of that supercharger fluid on me.
 
IF you do it just right, by using a flat screwdriver you won't even break the seal between the snout and case. Then you can drain it over an oil pan.
