there is a snout with MPS for sale on clubgp for $100. you should be able to snag a good one for less than that with a stock pulley. no re-build needed then.

I just walked the local pick and pull today and found all the SC cars already robbed of the charger complete, there is another pick and pull nearby I will check but think I still have time to shop.

Rickw said "And to answer one of your previous questions, the SC does not need to be timed or indexed from the motor, crank or cam in any way. It is totally independent of the engine and produces boost constantly. Unless it is unloaded by the boost by-pass valve during certain operating parameter's, so does not need indexing at all. Just remove and reinstall."

I was referring to the gears between the rotors as I have never removed a snout...yet.

I have a 98 with 48,000 miles
There is no indexing required anywhere on the sc. Be it between gears and rotors or the unit to the engine.

I do not want to replace the entire unit , just possibly the snout, the unmistakable sound of a bad bearing coupled with my attempt to suck out the silver flake colored goo lead me to believe the snout needs rebuild , thus my new quest to find a used junkyard snout in the next month or 2.

When the seal is bad does the fluid weep from the vent tip or behind the pulley?

And thanks,gotya on no timing for the rotor gears, slap it back on and go.

Are you saying that there ARE metal flakes in the goo you are removing? If so you definitely are looking at bearings, which would also explain the growl. Intense-racing.com and zzperformance.com sell snout rebuild kits with new bearings and coupler. Or you can get a used snout as mentioned before. You shouldn't have fluid leaking from behind the pulley unless the end seal is shot. The vent plug in the middle is where anything should come from.

The thing barely rattles, has a little slop with the belt off not a bunch but sounds growley to my ear and yes there is silver content to the pile of goo I extracted.

I am going to stick with the attempt to reduce/thin/extract/replace the goo while checking the local junk yards for new arrivals. I have no desire to change pully ratio at this time so if a used snout turns up with no flake I will get the green coupler and be on my way.... I hope

If you can find a good used snout for short money, that would be the way to go.
No need to change pulley sizes at all. Not now anyway,
Not until you've had a chance to do some more homework and purchase the supporting mod's anyway.
If you can't find a decent used snout soon, you can always rebuild your own, as you already know by now.

Look at www.darossillc.com for parts and kits as well.
