Has anyone ever experinced S/C oil leaing and accumulating under unit onto outlet mounting plate?? It is not coming from the front nose bearing seal or from any obvious telltail area. Kit has only 4000 miles since install and I need some good advice.

Many thanks,

Yes. It is leaking at the flange seal from flexing there. The Trilogy setup has too much length without snout support.

I have re-sealed mine a couple of times. It helps to use an activator with the anaerobic flange sealant. Also, after a new fill, open the fill plug when the blower is hot to let excess pressure out.

Yes, it's likely the front snout flange to the rotor pack flange. The seal is worn from flexing. Only way to fix is unbolt blower and take the snout off. Have to clean, seal and re-fill. It's a major job to fix correctly.

I suggest you check the fluid level every so often and always check when hot. Just don't let is run low or you'll need to rebuild the snout bearings.
 
Yes sir

I just got don fixing ken Johnson's

There is a way to fix it without ever having to worry about it again
 
Regular driving reduces the static stress allowing the dynamic stress to "spread" the loads reducing leakage.
 
Trilogy Snout

I have a variant on Don's problem of a year ago. The metal stress on the snout has caused a leak at the base of the upper driver's side rib on the snout where it attaches at the snout flange plate. Leaks right thru the aluminum, nowhere near the gasket.

Has anybody seen this failure on the Trilogy snout? My options so far seem to be:
1. Get a new/used snout. Unlikely, but does anyone have one?
2. Weld up the aluminum to reinforce it and go with ugly.
3. take it to Bobby Stiegemeier & let him fix it
4, find a twin screw, newer technology.

Any ideas? Would a too-tight idler pulley cause the extra stress? Is it, like me, just getting old?
 
S/C OIL LEAK

I still have the same issue today and have not removed the S/C to this date. I do keep a continuous check on oil level and one day will attend to this PITA situation. Keep me posted on your fix when you are ready to tackle issue at hand and I will gladly do the same.

Thanks,

I did not need to read this. Another thing to worry about.

If you are putting your Trilogy away for winter storage would you recommend removing the drive belt to relieve the stress?
 
The last time I resealed mine worked. One trick that helped was to remove the fill cap after the blower was heat soaked and re-tighten it. This reduces the pressure that builds up in the case from the heat cycles.

On a separate note, I still need to install my Whipple that I've been sitting on over a year.

I don't see the need to do this, but someone else may chime in and advise accordingly.

Take snout off the front of blower. Clean mating surfaces. Replace coupler if it needs it. Apply Napa Water Pump grey sealer to snout. Bolt on snout, fill with supercharger oil. Drive car.

I'm thinking any good welder could solve that for you. It shouldn't have to be ugly.
I would not buy another - it's old and used too.
3. let Steggy fix it.
4. upgrade blowers = WINNING!
