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.

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.

Wow, that SC oil looks like someone put motor oil in it instead of SC Synthetic oil along with some STP treatment (molasses).
Does it have a horrible smell.? If it was SC Synthetic and that dark it would smell like "Camel Ass", as someone on here so succinctly called it once.
And not knowing what Camel Ass smells like, I can tell you when I changed my oil it smelled like some creatures ass. I guess that is the nature of old SC oil.

BTW, is the Corvair running. If so, lets have a listen to that sometime.

not sure what to make of that sludge. i expected it to be darker and more chunky lol

almost looks like it got mixed with grease.

as for the smell, i think of rotting fish.

The other tech the next morning could not decide between fish and chlorine, but that was all the way across the shop and it could have been mixed by then, my helper said old gym socks, camel ass sounds fine to me.

The color is dark dark brown with smooth silver mixed in, not pump-able at room temp, I had gotten the rest out after mixing with 0-30 mobil one and pumping it at full operating temp 12+ miles on a 80 deg day.

The cap clearly had the factory paint "seal" untouched, remember this was a gently driven old mans car that basically sat 1 year, then was started and run hard randomly and not warmed up over the next 2.5 years doing blasts down the street, used a full tank of gas doing that, then sat again for 2.5 yrs , a total of 6 yrs.

Yes the Corvair runs!

Update:
I have since changed the SC oil 2 more times with Mobil 1, its still has the exact bearing noise and now a clearish thin brown with no metal flake or leaks and no worse noise, I will keep changing the oil every 500 or so miles until the color improves a little more , then get the right oil in there, OR I find a junkyard snout in between .

Hi Ed,

You should not run Mobil1 in your supercharger, if your car is a '98 (as your screen name implies). Only the '95 guys can do that. Nobody knows what weight the oil is supposed to be, and GM's supercharger oil is the only stuff you should run. It will cost you about $8 for the oil. By 'bearing noise' what do you mean is happening? Is it squealing? Screeching? tapping? What if you take the supercharger belt off? Could it be from a bad idler pulley? How does the S/C feel if you spin it by hand? Could it just be the tensioner?

Derek, if you read back a page, Ed's supercharger oil came out a nasty brown color. I think he was trying to "flush" it out with the motor oil, then switch back to reg SC oil once it looked clean.

Thanks all .

I am just buying time to find a SC car at one of the 3 local pick and pull . New green coupler awaiting the day I find the snout.

Yes a Corv8, if you want more double click on any vid , check out my other u-tube stuff, all car related,some past some present.

MultiCrazyCar

This vid was the first SC oil change, half of the time I was holding the cardboard at a 45degree angle without the oil pouring, the color change while finger stirring was not the cardboard showing through it was super fine silver metallic flake.

@ 98inSFl
To be call mid engine, the engine has to be in front of the rear axle
Or behind the front axle. like the Mazda RX8 or the Pontiac Fiero...... wink

Yes, if you allow for 'behind the front axle' config, Viper and Corvette are also considered mid-engine. I don't think most think of them this way, though.
