Vortech Oil Seal Going Bad?
I noticed today that I have oil leaking and getting sprayed around by the cog pulley on the back of my Vortech (See picture). Of course when I called them they had closed @ 3pm and I won't be able to get in touch until Monday. I doubt it is my oil feed line and I am almost certain this is a bad seal. There is not much info on this as I searched under "vortech seal" and only found four threads with limited info. Is this something I can replace at home or will I need to send into Vortech?
warranty goes kaput with the 2.87 pulley (or anything that breaks those wax 'seals'). just don't mention what S/C pulley you installed - the pulley on the blower should be stock unless you changed that too.
Please clarify what you mean by "oil getting sprayed around by the cog pulley"...is the oil dripping down behind the blower, or are you literally getting oil all over your engine? Where are you finding oil?
The oil is being sprayed on the hood and all around the rear cog pulley but there is not any oil on the belt. It seems to be coming from inside the pulley and is being sprayed out as it spins. I am 99% sure it is a bad seal which hopefully is easy to replace. I would love to get lucky and have it something I can replace with the supercharger still in the car. Anybody know what it takes to repair this?

i asked vortech in the past on the phone and they told me the 3 year warranty of the complete kit is taken to a 1 year warranty if the pulley is changed to 3.12 or 2.87
Would this be a good time to invest in a 928 Motorsports Impeller and a retune? Is this one of those things where if they have it apart already you should just have the whole thing rebuild?
Sucks that I have to pull the whole supercharger out. I was really hoping I could somehow remove the cog pulley and seal myself while it was still in the car....There is no way I can buy the part and do it?
That's what I did...
Their impeller is rated to 60k rpm, and their bearings are rated to 55k rpm...just be careful running that with a stock block...

350z400rwhp- if you have oil spraying from the back that means you need an output shaft seal.you cant change the seal with the blower still in place.. its impossible.. because you have to take the whole thing apart ( impeller first ) to get the the main gears.
While your at it, I would upgrade to the 928 impeller as well ( if your doing it your self ). you have to remove it anyway so might as well.
you dont have oil in front right? ex: by the filter or oil spraying from BPV? The rear seal aka output shaft seal ( the bigger of the 2 ) is very easy to find, however the input shaft seal is very different from the rear one. VERY VERY hard to find. vortech will not even sell it so dont even bother calling them. with that being said..
you can most definitely do the rear seal your self. pull 2-4 hrs out of your time and get it all done ( assuming you have all tools ) while your in there would be a good time to 1 change the impeller and inspect your bearings. or upgrade to faster ones if you would like. if your going threw with it,ill give you pointers where to watch out.. removing the impeller improperly can damage 9/10 times the input shaft seal as well as the 2 small bearings inside.
if you need any help just PM me as I have taking the vortech blower apart many, many times for a buddy of mine locally.

I'm guessing; Considering my slip issues as is, upgrading to the 928 changing the ratio even more. Would have to come up with another solution to the belts.
Anyone here tried sandblasting the SC pulley? Give a little texture to it, some traction. : )

Synjn-
Here is a thread I did and showed how I sand blasted my pulley. It did improve traction and I have no belt slip. The pictures are on page #2 of my thread. https://my350z.com/forum/forced-indu...g-pulleys.html
the language in their warranty is explicit about breaking those seals, and the warranty length is different depending on the blower (V2 = 3 years; V3 = 1 year unless you pay more). in the end, that document is the only thing that is legally enforceable.Warranty: http://www.vortechsuperchargers.com/...0-warranty.pdf

I have the GTM pulley upgrade. I'm more concerned with the power steering pulley squealing. The Timrod setup has a better contact area on this pulley and my car squeals for about 5 min until everything warms up even though my belt is super tight. This problem is not as bad when its warm out but really annoying when its below 60 degrees. I just want my car to start and not sound like a pos. I don't think I am having any belt slip issues with my supercharger at all.
Now i'm all ocd thinkin that my belt is too tight now.
I'm definately going to get my jackshaft pulley sandblasted now. Thanks for the help.

I'm going to call Vortech tomorrow but their turn time looks like 2-3 weeks and have already spoken with a guy at Supercharger Rebuilts.com. I may attempt to replace the seal myself but has anyone heard anything about Supercharger Rebuilts.com? They can sell me the part I need or replace both seals for $250. I'm leaning towards leaving the bearings alone as I will need a re-tune to go with a new 928 Motorsports impeller and all of that.
928 Motorsports also sells the seals, and also does rebuild services...
